Why do most mobile apps lose users after day one?
Slow onboarding, unclear value in the first 60 seconds, and crashes on real devices — not lack of features.
Measure time-to-first-value, not screen count. Flutter and native stacks both win when you instrument funnels and fix friction before buying ads.
What release discipline keeps retention high?
Weekly visible progress, staged rollouts, crash budgets, and store-ready builds — not heroics before every deadline.
I ship with CI, staged TestFlight/Play tracks, and rollback paths so growth spend is not wasted on a broken build.
