Which failure is hurting the most users?
Rank crashes, ANRs, and error spikes by affected sessions instead of raw occurrence count.

Questions Rejourney can answer
Start with the signal. Leave with evidence.
What happened immediately before it failed?
See the active screen, last gesture, request, and replay leading into the failure.
Is one release or device causing the spike?
Compare affected versions, operating systems, and device cohorts before prioritizing the fix.
From signal to answer
Stability issues are easier to fix when the session is attached
1. Crashes
Crashes
A stack trace can explain where code failed, but it does not always explain what the user was doing, which device was involved, or which release introduced the pattern.
2. Errors + ANRs
Errors + ANRs
Rejourney's stability workflow groups crashes, errors, ANRs, and API spikes, then keeps session replay, affected devices, app versions, and user impact close to the issue.
3. Replay context
Replay context
That gives engineering a faster starting point and gives product teams a clearer view of which stability issues are actually shaping conversion, retention, and support volume.

FAQ
Questions, answered.
What stability signals does Rejourney track?
Rejourney tracks crashes, errors, ANRs, and API error spikes, with replay and context that help teams understand the user experience around the failure.
Why pair replay with crash analytics?
Replay shows the path, screen, gesture, device, and state before the failure, which can make a crash or ANR much easier to reproduce.
Can product teams use stability monitoring?
Yes. Product teams can see which failures affect real user flows, while engineering gets the technical evidence needed to repair the issue.
