47 documented A/B tests from Blinkist, Duolingo, Headspace, Uber and others, each with the winning variant and the measured lift
abtest.design is a curated record of A/B test results from consumer apps, powered by Mobbin. Each entry pairs the A and B screens side by side, names the company, and states the measured outcome: Blinkist +23% trial signups on a reworked "How your free trial works" screen, Duolingo +40% learners on a streak after decoupling streaks from daily goals, Headspace +10% free trial conversion from multi-intent onboarding queries, HotelTonight +15% conversions from a streamlined checkout, Moonly +39% conversion from restricting the free trial to the annual plan, Mobbin +35% free-to-paid from a Pro badge, and a double-digit rise in rides per user at Uber from a clearer pricing estimate. The homepage carries 47 tests across seven categories: Paywall and free trial, Onboarding, Checkout and sales, User engagement and retention, Monetization awareness, Referral, and Misc. Anyone can submit a test. What separates it from a normal screenshot gallery is the outcome data — the collection is organised around what moved a number, not around what looked good.
Use this when a brief asks you to justify a paywall, onboarding or checkout decision, not when it asks for visual style. It is the only collection in this corpus that attaches a measured result to a screen, so it settles arguments the other galleries cannot. Read it before designing a free-trial flow: several entries contradict the obvious choice, notably Moonly gaining 39% by removing the monthly trial rather than adding one. Do not scrape it — the page is client-rendered and the substance sits in screenshots, so the outcome text is the only machine-readable part.
Why it is here. Nearly every design gallery collects appearance. This one collects consequence. For paywall, onboarding and checkout work it is worth more than a hundred pretty screens, because each entry names the company, the change and the lift.
