App Promo Video: How to Make One That Gets Installs and Signups
An app promo video is a short video that shows what your app does and why someone should install it or sign up. It is not a full tutorial and not a brand film. It has one job: get a viewer from 'what is this?' to 'I want to try it' in under a minute. This guide covers what to show, how long to make it, how to adapt it for each channel, and a script template you can copy. It applies to mobile apps and to web apps and SaaS products.
It is worth getting right. According to Wyzowl's 2026 Video Marketing Statistics report, 80% of people say they have bought or downloaded software or an app after watching a video (source).
What an app promo video should do
Most people watching a promo video have never heard of your app. They will give it a few seconds. So a good promo answers three questions quickly, in this order:
- What is it? One line, shown on screen as well as said.
- What does it do for me? The outcome, shown in the real interface.
- What do I do next? One clear action: install, sign up, or join the waitlist.
Everything else, such as the founding story, the full feature list and the roadmap, belongs on your site or in a longer product demo video.
How long should an app promo video be?
Shorter is usually better, but the right length depends on where the video will be seen. These are working ranges, not rules.
| Where it runs | Typical length | Aspect ratio | Notes |
|---|---|---|---|
| App store or product page preview | 15 to 30 seconds | Follow the store's specs | Show the core flow, not a tour |
| Social feed (X, LinkedIn, Instagram) | 15 to 45 seconds | 1:1 or 4:5 | Captions are essential; most feeds start muted |
| Stories, Reels, Shorts, TikTok | 10 to 30 seconds | 9:16 | Hook in the first two seconds |
| Landing page hero | 20 to 40 seconds | 16:9 | Silent loop or click to play |
| Launch day (Product Hunt, email) | 45 to 90 seconds | 16:9 | Room for a problem setup |
Check the current upload specs for each platform before exporting, since limits change. As of November 2026, Apple allows up to three app previews per language, each up to 30 seconds long, and they autoplay with the sound muted by default (source); App Store Connect also sets a 15-second minimum (source). On Google Play, the preview video is a YouTube link that may autoplay inline with muted audio for up to 30 seconds (source). If you want one master edit that works everywhere, build it at about 30 seconds and export it in several aspect ratios.
A scene-by-scene structure that works
A simple structure fits most apps. Treat the timings as proportions and scale them to your total length.
1. Hook (first 2 to 3 seconds)
Open on the result or the problem, not your logo. A finished report, a completed booking or a clean inbox is more interesting than a title card. Put a short line of text on screen so the video makes sense with the sound off. Google Play's own guidance for preview videos is to show the core features and content as early as possible, within the first 10 seconds (source).
2. The problem (3 to 5 seconds)
Show the old way briefly: the messy spreadsheet, the dozen tabs, the manual steps. Skip this scene for very short videos where the hook already implies the problem.
3. The core flow (10 to 20 seconds)
Show two or three steps in the real interface. Zoom into the part that matters and cut everything that does not move the story forward: loading states, settings screens and sign-in forms. Show one feature done well rather than six features skimmed.
4. The payoff (3 to 5 seconds)
Return to the outcome: the finished result, with realistic data. This is the moment the viewer decides.
5. The call to action (last 3 seconds)
Name the app, state the single action, and show where to do it. For a mobile app that is the store badge; for a web app it is the URL or button text. Do not offer three options.
Screens, motion and text: what to put on screen
- Use real product screens. Stock footage of people tapping phones tells viewers nothing about your app.
- Clean up your data. Use believable names and numbers, and remove personal information before you capture anything.
- Frame screens at a readable size. On a phone-sized video, a full desktop screenshot is unreadable. Crop or zoom to the part being discussed.
- Add motion with purpose. Zooms, highlights and transitions should point at what the viewer should notice, not just decorate.
- Keep text short. A few words per scene, large enough to read on a phone at arm's length.
- Caption everything spoken. Many viewers watch muted, and captions also help accessibility.
- Keep brand consistent. Use your logo, colours and fonts on every scene so the video looks like it belongs to your product.
App promo video script template
Write the script before you open any tool. Each line should map to something visible on screen. Copy this and fill in the brackets.
APP PROMO SCRIPT App: [name] Viewer: [who it is for] One action: [install / sign up / join waitlist] 1. HOOK (0:00-0:03) On screen: [the finished result] Text: "[Outcome] in [time or effort]" 2. PROBLEM (0:03-0:08) On screen: [the old, painful way] Text: "[Pain point in five words]" 3. CORE FLOW (0:08-0:23) Step 1 on screen: [first action] Step 2 on screen: [key moment, zoomed in] Step 3 on screen: [result appears] Text: "[Verb] [thing], [verb] [thing]." 4. PAYOFF (0:23-0:27) On screen: [finished result with real-looking data] Text: "[Concrete benefit]" 5. CALL TO ACTION (0:27-0:30) On screen: [logo, URL or store badge] Text: "[Action] at [url]" CHECKS - Works on mute with captions - Every line maps to a screen - One call to action only
How to make an app promo video, step by step
- Pick one audience and one outcome. A promo for 'everyone' persuades no one.
- Write the script using the template above, then cut it by a third.
- Capture your screens. Take clean screenshots or screen captures of each step, at the highest resolution available, with tidy sample data.
- Build the video. Use an editor, a motion design tool or an AI generator. Add captions, music and a voice-over if you want one.
- Export for each channel. At minimum, make a 16:9 version for your site and a 9:16 version for short-form feeds.
- Check it on mute and on a phone. If you cannot follow it with the sound off, or the text is too small, fix it before publishing. Phones are where most people will see it: in Unbounce's 2024 Conversion Benchmark Report, 83% of landing page visits were on mobile devices (source).
- Publish and measure. Track which channel and which version drives installs or signups, and rework the hook if people drop off early.
Ways to produce it: DIY, agency or AI
| Approach | Best for | Trade-off |
|---|---|---|
| Screen recording plus an editor | Teams with a video-savvy person | Flexible, but takes hours and editing skill |
| Motion design tool | Designers who want full control | Steep learning curve for non-designers |
| Video agency | A flagship brand film | Highest polish, highest cost and slowest turnaround |
| AI video generator | Small teams who need videos fast and often | Less hand-tuned control than a custom edit |

Common mistakes to avoid
- Starting with a logo animation. It uses your best seconds on something viewers did not ask for.
- Showing every feature. A promo that lists everything explains nothing.
- Relying on narration. If the video fails on mute, it fails for most feed viewers.
- Tiny text. Anything unreadable on a phone might as well not be there.
- Vague endings. 'Learn more' is weaker than 'Start free at your-app.com'.
- One cut for every channel. A vertical short-form version usually needs a different crop and hook from a landing page version.
If your promo is for a launch, pair it with the product launch checklist so the video goes out alongside the rest of your launch assets.

Frequently asked questions
+How long should an app promo video be?
For most channels, between 15 and 45 seconds. App store previews and short-form feeds work best at the shorter end, while a launch-day video on your site can run up to about 90 seconds. Always check each platform's current specs.
+What should an app promo video include?
A hook that shows the result, a brief problem, two or three steps in the real interface, a payoff, and a single call to action. Add captions so it works without sound.
+How do I make an app promo video without an editor?
Write a short script, capture clean screenshots of each step, and use an AI video generator to turn them into an animated video. Then check it on mute and on a phone before publishing.
+What size should an app promo video be?
It depends on the channel. 16:9 suits websites and YouTube, 1:1 or 4:5 suits social feeds, and 9:16 suits Stories, Reels and Shorts. App stores set their own requirements, so check them before exporting.
+Should an app promo video have a voice-over?
It is optional. Many viewers watch muted, so the video must work with on-screen text and captions alone. A voice-over can help on landing pages and launch-day videos where people choose to press play.
