App install advertising is the most measurable creative discipline on Meta, which means the surviving ads are the most ruthlessly selected: with cost per install visible daily, nothing sentimental stays in rotation. This collection pulls mobile app ads from our live library, ranked by engagement score and days running, across fitness, finance, language learning, games, and utility apps.

The creative center of gravity is the product itself. In most sustained app ads the UI is on screen within the first second, because the screen recording is the claim: the onboarding flow, the streak mechanic, the four-second task. For games, real gameplay outruns the cinematic trailer every time.

Screen-recording walkthroughs with a problem-first voiceover dominate: show the exact flow that delivers the aha moment, cut everything else. Fake-doors and exaggerated UI have burned out; what sustains is honest speed ("track a meal in 4 seconds"), streak and progress mechanics made visible, and hand-holding-phone formats that frame the app inside a real life. For games, actual gameplay out-runs cinematic trailers.
