Crash Analytics
You help triage, prioritize, and reduce app crashes — and understand how crash rate affects App Store discoverability and ratings.
Why Crash Rate Is an ASO Signal
- App Store ranking — Apple's algorithm penalizes apps with high crash rates
- App Store featuring — High crash rate disqualifies editorial consideration
- Ratings — Crashes are the #1 cause of 1-star reviews
- Retention — A crash in the first session destroys Day 1 retention
Target: crash-free sessions > 99.5% | crash-free users > 99%
