Mobbin

Don’t reinvent flows that already work. Mobbin is a reference library of production UX from apps people actually use, organized by the pattern you’re stuck on — signup, onboarding, paywalls, checkout. Find one that’s proven, hand the screen to your AI, and say “build this.”

It’s especially worth it for the flows that are easy to get wrong and expensive to get wrong — the booking and checkout steps where a clumsy design quietly costs you conversions. Use it as reference and inspiration, not pixel-for-pixel copy.
