By Mehdi, version 1.0.1
The studio I use to make my apps' videos, in code: a TikTok short, the App Store app preview video, a film. Claude writes the film using the method and the effects library; the tools measure the result frame by frame.

Three excerpts from the kit, as is.
Each effect is a function of time, with its use case, default settings and pitfalls. Eight sets: fundamentals, shorts, native iOS, data, typography, texture, transitions, camera.

Eight sets, each rated 9/10 by a second Claude instance using the kit's rubric: typography, native iOS, data, materials, transitions, camera. Each comes with its settings and its pitfalls.
A 12 s 9:16 short, the App Store page video header (iOS 27) and a real short from my app TradaZen, annotated.
Deterministic rendering with Playwright and ffmpeg, pre-render audit, MP4 checks: sync, loudness, flashes, clipped text, loop.
10 hooks, 40 visual worlds, 16 free fonts, 3,600 icons, 144 CC0 sound effects, and the Claude Code skill that applies the method.
The Starter Code comes from TradaZen, Solys and Nolera. The App Store Screenshots Kit reuses their screenshot sets and Vigie's. Check them out, they're on sale.

In January 2026, I was doing e-commerce. I had never published an app. I opened Claude and went for it.
With Claude, a prompt isn't enough. It needs code that runs, clear rules, and checks. The kit brings together what I learned publishing my apps. Got a question? Message me on WhatsApp, I answer myself.
Three steps, in order, and what the kit gives you for each.
One sentence, a format, a length, a call to action.

No. The film is an HTML, CSS and JavaScript file, rendered frame by frame by an automated browser. A fix is a line of code, not a timeline.
The kit gives Claude the method, the templates and the effects. You write the brief, watch the render and decide. The tools measure what your eye misses: flashes, sync, loudness, clipped text.
The kit ships 144 royalty-free sound effects and explains the mix. For voiceover, it covers a free local voice and ElevenLabs. No music is included: the kit tells you how to pick a track and sync it.
Since iOS 27, your App Store page can open on a video. The kit gives you the template at Apple's dimensions, with the safe zone and what's not allowed, and explains how to upload it in App Store Connect.
It doesn't generate AI video, and it doesn't ship music or 3D: everything is written in code, from your screens and your copy. It's built for iOS: the phone is drawn as an iPhone, and it targets the App Store app preview video. For Google Play, the 16:9 template works as your promo video.
