AppStills.Why your app needs a promo video
Video sells what a still can't
A promo video shows the app moving — screens arriving, features stacking up, the story building to a download. On social it's the only format that gets reach, and on your product page it holds attention longer than any screenshot row.
Your screenshots already did the hard work
You designed the screens; the video maker choreographs them. Every script starts pre-filled with your project's screenshots, brand colours and app name — you pick a storyline, not a blank timeline.
One project, three formats
The same project renders landscape for YouTube and product pages, vertical for TikTok, Reels and Stories, and square for feed posts. Each format has its own scripts, composed for that frame — not one video squeezed three ways.
From screenshots to MP4 in four steps
Pick a script
Choose from 15 ready-made storylines — feature tours, quick pitches, close-ups, three-reasons lists — across 16:9, 9:16 and 1:1. Every one opens pre-filled with your screenshots and colours.
Make it yours
Rewrite the headlines, swap screenshots per device, change device types, drag anything into place or type exact positions. Add, reorder or delete scenes from nine scene templates — including an empty beat for pacing.
Add music and brand
Pick a bundled soundtrack or upload your own, show your app name in the corner, and close on the generated logo screen with real App Store and Google Play badges.
Export the MP4
One click renders an H.264 MP4 — 720p or 1080p, 24/30/60 fps — right in your browser. Building and previewing is free; exporting is Pro.
The whole flow, from a project’s videos to the export dialog.
15 scripts, three formats
Every script is composed for its frame — a vertical cut is not a cropped landscape one — and each opens pre-filled with your project.
Landscape 16:9
YouTube, product pages, press kits and launch posts on X or LinkedIn.
Vertical 9:16
TikTok, Instagram Reels and Stories, YouTube Shorts — the formats that get organic reach.
Square 1:1
Instagram and LinkedIn feed posts, where square takes the most screen space.
App Store app previews, at the exact sizes
Promo videos are for reach; app previews are for the listing itself. App Store Connect only accepts previews at exact pixel sizes and 30 fps — so AppStills exports those separately: animate any screenshot with a camera move, or play a real screen recording inside a 3D device, and the MP4 comes out at 886×1920, 1920×886, 1200×1600 or 1600×1200, ready to upload.
Both come out of the same project as your App Store screenshots: one set of screens, one brand, every store size — and now the video. See what is free and what is Pro on the pricing page.
Frequently asked questions
Is the app promo video maker free?
Building and previewing videos is free — pick any script, customize every scene and watch the full result. Exporting the MP4 file is part of AppStills Pro ($5.90/month or $49.90/year), alongside one-ZIP screenshot exports, AI translation into 50 languages and app preview videos.
Do I need to know video editing?
No. You never touch a timeline: pick one of 15 scripts and it opens as a finished video with your screenshots in place. Editing means rewriting a headline, swapping a screenshot or dragging a device — the choreography is already done.
What formats can I export?
Landscape 16:9, vertical 9:16 and square 1:1, as H.264 MP4 at 720p or 1080p and 24, 30 or 60 fps — ready for YouTube, TikTok, Instagram Reels and Stories, and your product page.
Can I make App Store app previews too?
Yes. Beyond promo videos, AppStills exports App Store app previews at the exact pixel sizes and 30 fps App Store Connect accepts — either by animating a screenshot or by playing a screen recording inside a 3D device.
Can I use my own music and brand?
Yes — upload your own soundtrack or pick a bundled one, show your app name as a corner overlay in your project's font, and close on a generated logo screen with official App Store and Google Play badges.
Where does the video render?
Entirely in your browser. The frames are drawn by the same 3D engine you design in and encoded to MP4 locally — there is no render farm, no queue and no upload of your video.
