Google Firebase Test Lab vs. Userlytics

Test your app on devices hosted in a Google data center. Firebase Test Lab for Android provides cloud-based infrastructure for testing Android apps. With one operation, you can initiate testing of your app across a wide variety of devices and device configurations. Test results—including logs, videos, and screenshots—are made available in your project in the Firebase console. Even if you haven't written any test code for your app, Test Lab can exercise your app automatically, looking for crashes.
