Installs
Total installs — top of funnel, driven by store listings and marketing
Install-to-open rate
% of installs who open the app. 60–80% is normal; below signals onboarding issue
DAU / MAU
Daily / monthly active users. DAU:MAU ratio >20% is healthy for consumer apps
Session length
How long users spend per session. Depends on product; not always 'more is better'
Sessions per day
How many times users open the app. High-frequency products live or die on this
Crash rate
% of sessions that crash. <1% is standard bar; >2% drives uninstalls
Uninstall rate
% of installs that uninstall within 30 days. High is a sign of bad first experience
Push notification opt-in
% who accept push. Drops if you ask too early or too aggressively
5 Mobile-Specific Considerations
App update adoption lag — users take weeks to update; plan for old versions in production
Crashes correlate with device — specific Android models often disproportionately crash
Time-to-first-value on mobile is 30–60 seconds — much tighter than web
Store ratings matter — <4.0 star rating kills organic installs
App size affects installs — every 10MB adds friction on slow connections
5 Diagnostic Patterns
High installs, low opens — store listing problem (misleading or confusing)
High opens, low D1 return — onboarding problem
High D1, low D7 — early value problem
Flat session length — product novelty wearing off
Crash rate spike — recent deploy issue; roll back or patch fast
FAQ
What DAU:MAU ratio is good?
For daily-use consumer apps (messaging, news, social): >30% is good, >50% is excellent. For weekly-use apps (e-commerce, banking): >15% is good. For monthly-use apps (travel, special-purpose): >8% is good. Match the ratio to your expected usage frequency.
What's the biggest mobile metric PMs ignore?
Crash rate. PMs often fixate on DAU and retention while ignoring a 2% crash rate that's secretly driving uninstalls. A single persistent crash on popular devices can destroy retention for an entire segment. Monitor crash rate as aggressively as DAU; prioritise fixes above new features when crashes exceed 1.5%.
