Make an app demo video from your app's screenshots.
Use the screenshots you already made for the store listing. DemoScreen turns them into a vertical video with narration and music — for your store page, your website and social feeds.
A real render, made from screenshots.
Ambler is an invented product. These are its screenshots, rendered by DemoScreen with no manual editing.

Vertical first
Render 9:16 for Reels, TikTok and Shorts, or landscape for your website — from the same screenshots.
Readable on a small screen
On a narrow frame the camera stays inside close-ups, so text and buttons are never too small to read.
Narration in your users' language
Render the same video in English, Spanish, Portuguese or French by picking a voice in that language.
Three steps, no editing timeline.
- 01
Drop in screenshots
8 to 14 PNG or JPG screenshots, in the order they should play. Drag on any of them to mark up to four regions the camera should zoom into.
- 02
Let AI draft the script
DemoScreen reads the text on your screens and writes the narration, one line per scene. Edit any line, or rewrite it with a short note.
- 03
Pick a voice and render
Choose a narrator and a music bed, add your logo to the end card, and press Make video. A 1080p MP4 and an SRT caption file arrive by email.
Free to start; paid plans from $9 a month. One credit is one second of finished video. See pricing.
Before you start.
Can I use it as an App Store preview?
App stores set their own rules for preview videos, including length and what may be shown. Pick the 30-second length and check the store's current guidelines before uploading.
Do I need a screen recording of the app?
No. Screenshots are enough — the motion comes from zooms, pans and cuts timed to the narration.
Is there a free plan?
Yes: 60 free credits to start, which is one minute of video, rendered in 720p with a small watermark. They don't expire.
