App promo videos that get installs

An app promo video is a short screen-led video that shows what your app does and asks for the install. You need three cuts of it: an App Store app preview of 15 to 30 seconds, vertical install ads with a hook up front, and for SaaS, a product demo built from screen recordings.

One shoot, three cuts

The store preview explains. The install ad interrupts. The demo proves. Make all three from the same capture.

  • The app preview

    Lives on your store listing and autoplays muted. Real screen captures, the best feature first, captions instead of voiceover. It can only show the app, so no people filming phones.

  • The install ad

    For Meta, TikTok and the in-app networks. 9:16, hook in the first three seconds, a person or a payoff before the UI. Game studios have this down to a science, see mobile game ads.

  • The product demo

    For SaaS. A screen recording zoomed to the click that matters, one workflow from problem to result, captioned. Twenty to 45 seconds for ads, longer on the site.

SaaS product demo video ads

Software sells the same way: one pain, one workflow, one result on screen.

How to make an app promo video

Record the screen clean, script the first three seconds, cut to each platform’s specs.

  1. 1

    Record clean captures

    Demo data that looks real, notifications off, the status bar tidy. Record at the store resolution so the app preview needs no rescale.

  2. 2

    Pick one feature per video

    The app does twenty things. The video shows one. Duolingo’s chess ad is about chess.

  3. 3

    Write the hook before the edit

    Problem, payoff or person in the first three seconds. Patterns in ad hooks.

  4. 4

    Zoom to the click

    Screen recordings die at full frame. Push in on the tap, the result, the number that changed.

  5. 5

    Caption everything

    Previews autoplay muted and most feeds do too. If it only works with sound, it does not work.

  6. 6

    Cut per placement

    9:16 for Reels and TikTok, 16:9 for YouTube, the device sizes for the store. Per-platform specs in ad specs. For editing with AI, see Claude video editing.

Questions

What is an app preview?

A short video on your App Store listing that autoplays muted in search results and on the product page. Apple allows up to three per localization, each 15 to 30 seconds.

How do I make app promo videos for Apple Search Ads and TikTok app install campaigns?

Apple Search Ads draws on your App Store listing, so the app preview is the creative there. For TikTok, cut 9:16 install ads from the same screen capture with a hook in the first three seconds, and make several versions so the algorithm has options.

Who makes App Store preview videos and app ad creatives?

App marketing studios, freelance motion designers, or the team in-house with a screen recorder and an editor. For a weekly stream of install ads rather than a one-off preview, a done-for-you service like Director by Sprites fits.

What is the best way to make SaaS product demo video ads from screen recordings?

Record one workflow end to end, cut it to the moment the result appears, zoom in on each click, caption it, and open on the problem rather than the login screen. Run 9:16 on Meta and 16:9 on YouTube.

How long should an app promo video be?

15 to 30 seconds for the App Store, which is Apple’s limit. Six to 30 seconds for install ads. A product demo for ads lands at 20 to 45 seconds.

Can I make an app promo video with AI?

Partly. AI video models make good openers and B-roll, but your UI has to be real screen capture. See which models hold up on ad briefs in the Creative Arena.
