When Apple introduced Swift, their new programming language, at this year’s WWDC, like you our engineers didn’t waste any time and dove in to see what it was all about. After spending the past few months testing out support in our developer preview, we’re excited to announce Crashlytics official support for Swift!

Build How You Want, Where You Want

At Crashlytics, we’re huge supporters of making it as easy as possible to develop mobile apps. When Apple promoted Swift as a language that was easier to read and maintain, we knew we wanted to get on board. In anticipation of Apple’s upcoming announcement, we’re rolling out our official support so that developers can quickly get up and running. Our support for Swift provides developers with the flexibility they need to build inside their existing workflows and streamline the overall development process.

Our engineers worked tirelessly updating our backend to support the demangling of Swift crashes and took meticulous care to preserve our seamless onboarding and pristine UI. To provide you with a customized onboarding experience, our Mac app allows you to choose between building with Objective-C or Swift. Whether you’re new to Crashlytics or migrating to this new language, you’ll experience the same powerful features, combined with native support for Swift based builds.

Today, we’re excited to unveil our latest project: Answers by Crashlytics. Finally, mobile analytics you don’t need to analyze.

When we first launched Crashlytics more than two years ago, we were focused solely on solving the problem of mobile crash reporting. Since then, we’ve seen a need for powerful tools across other areas of app development — and we knew that we could apply the same design principles to meet the many challenges faced by today’s mobile app developers. With Answers by Crashlytics, along with our award-winning crash reporting tool and Beta by Crashlytics, developers now have access to a powerful, lightweight suite of products to help them not only build, but also grow great apps.

It’s been an honor to work with many of the top iOS and Android mobile teams as we have crafted Answers, and we’ve received incredible feedback:

We have Answers by Crashlytics displayed on two of our big TVs (one for iOS and one for Android) so the entire team can view the live updates of our app’s key metrics — everyone loves it!

Lars Vedo, Mobile Product Manager,

Zero Steps

Terms like ‘bloated’, ‘bulky’, and ‘unreliable’ should never describe any developer tool. We know how hard it can be to gather real-time data, gain actionable insights about user behavior, and iterate quickly to optimize your app. Don’t worry — this is what we do.

Answers streamlines the process of revealing the key drivers of your app’s growth. With just one click, and no extra code changes, you’ll have the power to understand your app’s key usage and retention metrics. We intelligently and quickly send data at low impact times to optimize and reduce traffic on your app. Built into our existing Crashlytics SDK, Answers gives you instant visibility and a constant pulse on your app’s key metrics. And it’s free.

A Dashboard That Makes Sense

Your time is precious. We don’t want to bog you down with data overload. Answers streamlines your day with a UI that calls attention only to your most critical app usage metrics. With full visibility into your growth and engagement indicators, you can immediately understand the current state of your app and intelligently decide where to invest your time.

See a spike in activity? We’ll tell you why. No more guessing if an increase in daily actives is a result of new users or your existing users becoming more active. We’ll connect the dots for you.

And if you’re anticipating increases in usage related to a major event, you can see at a glance how many users are engaging with your app at this very moment. Bring the popcorn and display this data for your team to watch the action live.

No Analysis Required

Once enabled, Answers by Crashlytics intelligently analyzes and learns your app’s behavior and begins delivering live data within minutes. We know you’re busy, and we’ve built Answers with that in mind. You no longer need to don a lab coat and pull out a calculator to understand what’s going on. We look at the long-term trend and understand that there are certain metrics that are cyclical, so we’ll proactively alert you when a pattern is truly abnormal.

You’re constantly pushing out new features and bug fixes, so you’ll want to understand how your top builds compare and how users are engaging with your latest build. View build adoption over time to see the stability of each build with a breakdown of session length and crash-free users per build.

All About Growth

We know that retention is an important metric for understanding growth — that a large increase in new users doesn’t always translate to a long-term increase in your monthly actives. At a glance, monitor what percentage of your new users are coming back within a day, week, or month of installing your app for a clear picture of true user retention.

Sometimes, simply knowing usage numbers isn’t enough to understand overall performance. Answers dives deeper, showing you the total number of user sessions and the average number of sessions per user. For more granularity, we include the median session length, along with the amount of time per day the average user spends in your app. What better way to know that your users are having an awesome experience than to see them spending more time in your app?

Finally, app stability is crucial to ensuring your users have a great experience. Know how many of your users are having crash-free days and crash-free sessions and instantly see the top issues related to your app’s stability. Since Answers is built into the same SDK that powers your crash reporting, you can immediately dive into the issues that have the greatest impact and start fixing bugs.

Experience the Power

This is just the beginning. Our engineers are already working to take Answers to the next level and we have a lot planned. As always, send us your thoughts at support@crashlytics.com or find us on Twitter @Crashlytics. We’d love to hear what you think we should tackle next.

If you already have a Crashlytics account, you’ll soon see the new Answers tab on your dashboard. Otherwise, sign up here to get started with Crashlytics.

Don’t just take our word for it:

Answers by Crashlytics is the first thing I check every day. Its breakdown of crash-free users and crash-free sessions are the fundamental metrics we use to measure the stability of our app. I can’t imagine shipping an app without it.

Ryan Johnson, VP of Mobile Engineering,

Answers by Crashlytics is exactly what we’ve been looking for! We just launched a new version and it was amazing to immediately compare it’s stability to our previous versions.

Philip Connaughton, Software Engineer,

Just one year ago, we announced our open-sourced integrations, inviting the developer community to build on our existing infrastructure. Since then, we’ve had many developers build and submit integrations that are used today by thousands of other developers! We’ve loved seeing the community support and are excited to announce three new integrations to help you strengthen team collaboration and manage your projects.


Since you’re constantly multitasking, we know you’re relying on Red Bull and to-do list tools like Trello to help you manage and prioritize your workload. Our integration with Trello, built by Andrey Chernih, allows you to turn your crashes into Trello cards. Add your crash cards to any of your Trello boards so you can see what crashes need your attention and collaborate with your team to understand who is working on each crash.


Built by Mufri, our Bitbucket integration turns your crashes into Bitbucket issues that are added to your preferred repository. We know your time is valuable and with this integration you can seamlessly jump from your Bitbucket repository directly into your crashes. With this seamless integration, you now have more time for the fun stuff, like coding the next hottest app!


We understand the importance in team collaboration and being in constant communication to understand who’s working on what. Andy McSherry built the Crashlytics integration with messaging service Hall. With this integration, messages are posted into your preferred group so you can quickly and easily communicate with your team about your crashes. No more waiting by the water cooler to track down teammates for status updates, we’ve got you covered. ;-)

Interested in adding your own integration? We’d love to work with you and see what you can come up with. See our existing integrations and get started.

At Crashlytics, we’re passionate about building tools that developers love. Three months ago we announced a new Crashlytics Labs project: a beta distribution tool to simplify the process of sharing apps with testers. Since then, we’ve seen an overwhelming demand from iOS and Android developers wanting to get their hands on our latest tool, and the feedback has been outstanding.

I love that we can manage everything from testers to builds in one place — for both iOS and Android. This is a huge improvement in our workflow.

Nicolas Melo,

Hundreds of top mobile developers have already distributed their apps to thousands of testers, and we still have people excited to experience what all the hype is about. In response to this demand, we’re excited to announce the official launch of Beta by Crashlytics. This means it’s now fully supported by our engineers, designers, user experience folks and amazing support team, among many others. This also includes a rapid release cycle, so you can expect continuous updates for features and bug fixes automatically and on a regular basis.

The Most Streamlined Beta Distribution Experience.

We’ve heard your frustrations about the state of beta distribution today. Poor UI, confusing registration systems, frequent downtime, and only single-OS support. It’s time to build something usable with both developers and testers in mind.

We applied our Crashlytics power and polish to this problem. The result: a streamlined experience for distributing apps that gives you a single, cross-platform toolset for iOS and Android. Beta distribution should be an intuitive process for you and your testers so you can focus on what matters — building your app, not stressing about getting testers up and running.

With Beta by Crashlytics, you can easily invite new testers through a seamless sign-up workflow, manage testers on the web or right within your IDE, and analyze key metrics to determine when your app is ready for prime time. Combined with our crash reporting solution, there is now a one-stop-shop for debugging and distributing apps. Oh, and it’s free.

Your App, Front and Center.

With the R&D efforts inside Labs, we’ve applied many of our major breakthroughs to Beta by Crashlytics. With only one chance at a first impression, it’s crucial to deliver a high-quality, fluid tester experience. Beta by Crashlytics helps you invite or onboard testers and send builds with just a few clicks. We authenticate the device without requiring user registration. This results in a dramatically noticeable reduction in the time it takes to get your testers up and running.

Your app and brand should be front and center, not buried behind unnecessary UI chrome or colors. Beta by Crashlytics intelligently analyzes your app’s icon and automatically tailors the tester experience to match your apps’ color scheme. The experience for your testers will be seamless and consistent with your brand.

Your Workflow, Uninterrupted.

Beta by Crashlytics is deeply integrated with our existing IDE plugins for Xcode, Android Studio, Eclipse and IntelliJ. You can now invite testers, distribute new builds and enter release notes all via our Mac app or Android IDE plugins. Using a build server? We’ve got you covered. Just upload your build, add testers and you’ll be up and running with just a few tweaks to your build script.

To ensure testers have a great experience, we’ve taken a proactive approach when working with Apple’s provisioning portal by identifying testers that you’re missing UDIDs. On Android, as soon as your testers install the Beta by Crashlytics app, it’s automatically customized and bootstrapped so your app is ready to be launched and tested.

All Your Testers, All in One Place.

The only thing more important than getting your testers up and running is managing and understanding their status. With our web dashboard, you can view the progress of your testers in a sleek racetrack UI. At a glance, you’ll see who is most active or who is still ignoring your invitations. Also, see a high-level view of most recent tester activity to identify new tester status.

Collaborate with your team without being in the same room. Our audit trail shows the most recent developer activity as your team distributes, updates release notes and invites more testers. Want to troubleshoot reported issues with your app? See a high-level overview of your top issues. With just one click you’ll be in your Crashlytics Issues dashboard, with all of our deep analysis tools to help you debug the most complex crashes. Get performance insight, starting with beta testing, all the way through App or Play store distribution.

What’s Coming.

We have a pipeline of features rolling out over our rapid release cycle. Over the next few weeks, you’ll see the beta distribution icon appear on the left sidebar of your existing account. Our dashboard will immediately get you up and running in just a few clicks. Existing customers, learn more on the Beta page and see our updated ToS and Privacy Policy. New customers looking to experience the power of Crashlytics, sign up here.

Don’t just take our word for it:

Setup was a simple drag-and-drop, and the process for sending builds to testers is a no-brainer. This is exactly the beta distribution solution we’ve been waiting for on Android!

Stephen Parish,

We do several hundred internal app releases a year and many times twice a day. Crashlytics has made this monotonous task, ultra lightweight, efficient and painless.

Tony Longo,

Crashlytics’ beta tool is, hands down, the simplest to use. Getting started took almost zero effort and their integration with XCode is excellent. I love how it does all the work of preparing and distributing builds for me all the way down to automatically detecting new archives.

Allan Carroll,

Whether you develop for iOS or Android, are working at a large company or hustling as a freelancer, chances are you’re hacking on many apps at the same time. Working on all these apps leads to the pain of managing all their notifications, which we know can sometimes be overwhelming.

We love supporting you in your development efforts and we heard you loud and clear when you told us that you wanted more control and simplification when managing your settings. Thanks to all your feedback, we set out to make managing your settings a top-notch experience, so you can get back to the fun stuff: writing code and building the next big app for millions of users!

Seamless, Intuitive Navigation

We started off by revamping our UI, moving away from modals, and utilizing a full canvas, providing ample space to display all your settings details. Previously settings dashboards were organized at the app level, which required you to switch between each app in order to access the app’s settings. To make this process easier, we added high level lists with views allowing you to instantly access the settings of all apps under your account.


For those of you who manage many apps, belong to many organizations, or have large teams, we’ve added searchable fields for each category. Our new search offers a seamless, real-time filtering based on your query term, so you can quickly and easily find what you’re looking for with very little effort.


Powerful, Streamlined Notifications

With our new notifications we want to put the control in your hands for whether or not you receive alerts for your apps. Previously our notifications were very granular and required more management, especially when adding a new app. We’ve tailored this experience so that you only have to set your preferences once! By choosing “watch”, you automatically assign the preferences you’ve selected to all your apps, or you can stop watching to not receive any notifications for a particular app.

With multiple apps in your account, it can be overwhelming to adjust their settings individually. Our new dashboard offers a completely streamlined process for you to select how you want to get notified. As you view your list of apps, you can easily toggle between watching or not watching. We’ve also added the ability to set a default category for new apps that are added to “watched” or not.


Intelligent, Flexible Email Routing

One of the most widely requested functionalities that we included in this revamp is the ability to assign a confirmed email address to each org when receiving notifications. For developers with multiple orgs, we understood the need to customize where you receive your notifications. You can now assign a confirmed email address for each of your orgs to receive your notifications!

Lightweight, Premium Performance

With this new functionality also comes significant performance improvements. While we’ve added significantly more data requests and provided more information for each request, we’ve increased page speed by over 4200%. Moving away from modals to URL driven displays allows you to quickly access the information you need and jump right back into whatever it is you were working on! With these speed improvements transitions to and from settings are faster allowing you to get in and out of settings quickly dive back into your dashboard without disrupting your workflow.

Optimized Collaboration Experience

It’s now easier to invite multiple members of your team to join your org, all at once! We want to help you get your team up and running as quickly as possible, so we’ve simplified the process of adding team members.

We are very excited and proud to show you our new Settings dashboard. We hope that this will give you the best experience in managing your app settings and help you achieve top performance for all your apps. Log in to your new settings dashboard or sign up for Crashlytics and give us your feedback!

While sheer performance and deep insights are essential in a crash reporting solution, we’re passionate about also delivering an unparalleled user experience. After launching our optimized stack traces just a few weeks ago, we were heads down again meticulously refining our user interface and reporting features. With the latest Crashlytics real-time interface, you can now keep tabs on your most prevalent crashes with prominent, intelligently organized crash notifications — inside an optimized, redesigned navigation experience.

Additionally, for the very first time, we’re offering an effortless, one-click sign in using your Twitter account!

Dynamic, Real-Time Notifications

You just never know when a critical issue might occur and require your immediate attention. While we’ve always offered real-time functionalities in our web dashboard, we wanted to take the experience even further. Our new notifications system keeps the interface even more pristine, with real-time alerts appearing on the lower righthand corner.

As subsequent crashes come in, the alert box automatically updates itself in real-time, grouping crashes by type so they don’t pile up! Additionally, each alert displays the filename and line number prominently for easy identification. Now you can know exactly how many new crashes there are and scan through all of them with minimal effort — without any incoming crashes disrupting your flow.

From our friends at Blackboard:

Our dashboard is composed of hundreds of apps with thousands of app versions. Refinements to the navigation and the incorporation of real-time notifications on the dashboard have made it incredibly simple to zero in on a problem and trace it to a solution. Crashlytics is by far the best solution to monitor, track, and resolve crashes at scale.

Bryan Musial,

Intuitive, Responsive Navigation

Tackling complex bugs can be a frustrating process for many developers — let alone having to manage the process across multiple apps and organizations. For those of you with multiple apps, our new context control now automatically orders your list of apps based on recent interactions. Coupled with a seamless search functionality, the apps you’re most actively managing are always at your fingertips.  Each app is also labeled with its corresponding organization, so you know precisely where it belongs.

Since the birth of Crashlytics, we’ve continually upgraded the navigation experience with highly visible tabs and efficient menu structures. To take the experience to the next level, we made our new navigation sidebar ultra-thin which maximizes the horizontal space for displaying all the critical crash data. We also replaced the tabs with slick, eye-catching buttons.

In our newly redesigned menu structure, each button has a drop down menu that gives you seamless access to all of the following options:

  • Add a new app, organization or account
  • Manage settings across your apps, organization and account
  • Access the Crashlytics Knowledge Base, TOS and blog
  • Download plugins

As your app scales and acquires more users, the issues list can get quite long, requiring you to scroll down. Our new navigation bar now rests in a fixed position on the left side, so you’ll always have access to the app selector as well as all the menu items as you scroll up or down. Given all the different screen sizes in today’s world, we’ve also made our navigation bar vertically responsive which automatically adjusts to the height of the browser window.

Seamless, One-Click Twitter Sign In

Ever since we joined forces with Twitter, we’ve been accelerating our build-out and remain dedicated to delivering the key app performance insights that every developer needs. With Twitter’s infrastructure, we hoped to deliver new features faster than ever before. Today, we officially announce that you can sign into Crashlytics with our one-click, OAuth integration with Twitter.

For existing Crashlytics users, you will be able to link your Crashlytics account to your Twitter account during sign in. Once you’ve synced up the two accounts, it’s just one simple click the next time you sign into Crashlytics!

As we continue on our mission to improve the debugging experience for developers all around the world, we couldn’t wait to get these upgrades into your hands. Sign in or request an invite to experience the new Crashlytics interface — we’re always eager to hear your feedback!
