50 Mistakes Across 4000 Apps - Product, UX & retention mistakes founders keep repeating

by
Most apps don’t fail because of bad code; they fail due to confusing onboarding, weak retention, feature overload, friction, and poor product decisions. After analysing 4000+ apps, I noticed the same patterns repeating everywhere. So I created “50 Mistakes Across 4000 Apps”, a free practical guide covering UX, onboarding, retention, growth, and product mistakes for founders, PMs, indie hackers, and startup teams. 🚀

Hey Product Hunt 👋 Over the years, I’ve explored more than 4000 mobile apps while building products, analysing UX patterns, studying onboarding flows, and observing why some apps retain users while others quietly fail. One thing became obvious: Most products repeat the same mistakes. Not because founders are bad builders, But because product friction is often invisible while building. So I created this free guide to document the recurring patterns I kept noticing across apps: * onboarding mistakes * UX friction * retention problems * feature overload * weak positioning * execution gaps My goal was simple: Create something practical that founders and builders can immediately apply to their own products. Would genuinely love your thoughts, feedback, and the biggest product mistake you repeatedly notice in apps today 👇
