An app promo video is the short clip that sells a mobile app before anyone installs it: on the store listing, on your landing page, and inside paid install ads. UGCGen is an AI app promo video maker that turns your app store listing into a presenter-led promo video, writes the script, casts an on-screen creator, burns in captions, and exports the ratios each placement needs. You supply real screen recordings of the app; the tool handles everything around them. The win is that testing three hooks costs the same as making one.

What is an app promo video?
An app promo video is a short marketing clip that explains what a mobile app does and why someone should install it. It shows up in three places that matter: the App Store and Google Play listing, the app's landing page, and the paid campaigns that drive installs on Meta, TikTok, and Google. Each of those places has its own rules, which is why one file rarely covers all of them.
It is worth separating two things people lump together. An App Store app preview is a specific asset built from real app footage, capped at 15 to 30 seconds, that autoplays muted in search results. A promo video is the broader idea: it can open with a presenter naming the problem, cut to the app solving it, and close with a reason to download. The store preview is a subset of the promo video, sized and trimmed for one placement.
For app marketers the constraint is the same one every performance team hits: creative volume. Install costs rise the moment one video fatigues, and the fix is a fresh angle, not a fresh audience. A mobile app promo video maker that produces several presenter-led variants from the same listing lets you keep a rotation of hooks running instead of riding one clip until it dies.
Where an app promo video runs, and what each place wants
These are the working defaults as of July 2026. Apple, Google, and each ad network publish their own current spec sheets, so confirm before you upload.
| Placement | Format | Length | Notes |
|---|---|---|---|
| App Store app preview | Portrait or landscape, from device | 15 to 30s | Up to 3 per localization. Autoplays muted in search. Built from real app footage. |
| Google Play promo video | YouTube link, 16:9 | Around 30s | Sits above the screenshots. Plays with sound when tapped. |
| Google App campaigns | 9:16, 1:1, 16:9 | 10 to 30s | One asset served across YouTube, Search, Play, and Display. |
| Meta app install ads | 9:16, 4:5 | 15 to 30s | Hook in the first 3 seconds. Captions expected, sound often off. |
| TikTok app install ads | 9:16 | 15 to 30s | Native, sound-on feed. UGC style outperforms polished promos. |
| Landing page hero | 16:9 or 1:1 | Under 60s | Muted autoplay, captions on. Show the app in the first frames. |
Running the paid side too? The YouTube Shorts ads and TikTok ad generator pages cover the campaign setup for install traffic.
How to make a mobile app promo video
Paste the app listing
The tool reads your app name, description, and category so it can write a script that names the real problem your app solves.
Add your screen recordings
Drop in short clips of the app in use. The store and the ad both need to show what the app actually does, not just a talking head.
Pick a presenter and hook
Choose who fronts the video and the opening line. Generate two or three hooks so you have variants to test on paid traffic.
Export per placement
Download watermark-free files with captions burned in, one per ratio, ready for the store listing and every install campaign.
One rule keeps app promo videos honest: the presenter sets up the problem, but the screen recording has to prove the app solves it. Reviewers and ad networks both reject videos that promise a feature the footage never shows. If you are also cutting a longer walkthrough of the interface, the product demo video maker page covers that format, and the UGC ad script generator drafts the hook variants.
Four ways to get an app promo video made
Each route is right for a different stage. This is about matching the method to the job, not naming a winner.
| Method | Typical cost | Turnaround | Best for |
|---|---|---|---|
| AI app promo video maker | Flat monthly plan | Minutes | Hook testing, install-ad volume, pre-launch apps |
| Motion designer on Fiverr | Roughly $150 to $600 per video | 3 to 7 days | A single polished store preview or launch trailer |
| App promo video agency | $1,500 to $8,000+ per video | 2 to 6 weeks | Funded launches, brand films, live-action shoots |
| DIY template tool | Low monthly plan | Hours | A quick screenshot slideshow, if that is all you need |
Where an AI maker does not fit: if your launch needs a live-action trailer with real actors on location, that is an agency job, and this tool will not replace it. It replaces the weekly grind of feeding fresh install-ad creative into Meta and TikTok.
Who a mobile app promo video maker is for
App marketers and UA teams

App agencies
Every client needs fresh install creative every week. Generate the batch, run it, report the cost per install.
SaaS with a mobile app
A presenter framing the problem converts better than a silent screen recording on cold social traffic.
Game studios
Show the loop in the first three seconds. Generate hook variants that lead with different moments of play.
Fintech and health apps
Lead with the outcome, keep every claim truthful, and let the screen recording carry the proof.
App promo videos, answered
How long should a mobile app promo video be?
For an App Store app preview, keep it 15 to 30 seconds, which is the range Apple accepts. For a Google Play promo video, around 30 seconds works well. For paid app install ads on Meta, TikTok, and Google, aim for 15 to 30 seconds with the core benefit and a screen of the app inside the first five seconds.
What is the difference between an App Store app preview and a promo video?
An App Store app preview is captured from actual app footage, must be 15 to 30 seconds, and autoplays muted in search results. A promo video is a broader marketing asset: it can feature a presenter, a hook, and lifestyle context, and it runs on Google Play, your landing page, and paid install ads rather than only inside the App Store.
Can I make an app promo video without filming?
Yes. An AI app promo video maker casts an on-screen presenter, writes the script from your app store listing, generates the voiceover, and burns in captions, so you never point a camera at anything. You still supply real screen recordings of the app itself, because the store and the ad both need to show what the app actually does.
Do app promo videos increase installs?
A clear promo video usually lifts conversion on the store listing and lowers cost per install on paid campaigns, because most people decide from the first frames rather than reading the description. The size of the lift depends on the app and the creative. Treat the video as a test, run two or three hooks, and keep the one with the lowest cost per install.
What size should an app install video ad be?
Use 9:16 vertical for Meta and TikTok app install ads and for YouTube Shorts placements in Google App campaigns. Add a 1:1 or 4:5 version for feed placements and a 16:9 version for in-stream YouTube. Export every ratio you plan to run rather than letting the network crop your ad automatically.
Does Apple allow a presenter in an App Store app preview?
The App Store app preview itself must be built primarily from app footage, so a full talking-head intro is risky there. Use the presenter-led cut for Google Play, your landing page, and paid install ads, and keep a footage-first version trimmed to 15 to 30 seconds for the App Store slot.
