App Store screenshots & copy. Design free, pay once to export.
StoreCanvas is a Mac app that builds the whole listing in one place: device-framed screenshots at the exact pixel sizes Apple requires, a copy center with live character counters for every App Store Connect field, an app icon generator that exports the full set, and a listing preview that shows the whole thing the way shoppers will see it.
Local-first: your projects, screenshots and settings stay on your Mac. No account, no analytics, no tracking.
Drop in a screen capture, frame it in a real device, add a headline. Export at the precise pixel dimensions App Store Connect requires. No more rejections for wrong dimensions.
Every App Store Connect field with a live character counter. Amber as you approach the limit, red at it, and the field simply stops. Write your title, subtitle, keywords, description and release notes without ever pasting into App Store Connect to find out you were 12 characters over.
Design the icon once and export a drop-in AppIcon.appiconset plus the App Store 1024. Every iOS and macOS size rendered for you, opaque and square, the way Apple wants them.
The Preview tab assembles your icon, title, screenshots and description into a realistic product page, so you know exactly what shoppers will see. Export it as a PNG for feedback. That export stays free.
Connect Claude, ChatGPT or Gemini with your own API key and StoreCanvas drafts your copy and generates background art. The key stays on your Mac and calls go to the provider directly. Nothing proxied. Entirely optional: everything works without it.
Build one, two, or all three platforms per project. Each is an independent set, exported at its own sizes.
Two lines of marketing copy per screen with fully independent typography. Pair a heavy display headline with a light supporting line.
Add any .ttf, .otf, or .ttc, Google Fonts included, and reuse it across every project.
Sync text, background, or device styling across every frame and platform in one click.
Every image you generate is saved automatically. Reuse it on any screen, platform, or project. Generate once, use forever.
Archive a version before starting the next. Exports organize themselves into version folders: v1.0/iPhone/, v1.1/Mac/.
StoreCanvas is bring-your-own-key. Paste an API key from the provider of your choice. It is stored only on your Mac, and StoreCanvas calls the provider directly. Atlas Learning Group never sees or proxies your key, your prompts, or your tokens.
| Provider | Can do | Best for |
|---|---|---|
| Anthropic (Claude) | Text | The strongest App Store copywriting: titles, descriptions, keywords with real nuance |
| Google (Gemini) | Text + images | Generous free tier. The easiest way to start |
| OpenAI (GPT) | Text + images | Solid all-rounder for text and images |

Build as much as you like for free. A single unlock enables exporting, forever, on every future update. StoreCanvas is yours for life.
Shown once, quietly, if you pass on the unlock the first time. Maybe later dismisses it. Still one-time; still never a subscription.
No accounts, no analytics, no trackers, no proxied keys. Local-first is a promise, not a feature.
No. StoreCanvas is a one-time purchase: $29.99, yours forever, every update included. Design everything free and pay only when you're ready to export.
Only exporting your finished assets. Designing screens, writing copy, generating with AI, and previewing the listing are free and unlimited. Exporting the listing preview stays free too, so you can always share a mock for feedback.
No. Screenshots, icon, copy editing, and preview all work without AI. The key only powers ✨ generation.
On your Mac. Keys live in the app's local settings and calls go straight to your provider. Projects are files in ~/Library/Application Support/StoreCanvas/.
The current App Store Connect requirements: iPhone 1320 × 2868 (and the other accepted sizes), iPad 2064 × 2752, Mac 2880 × 1800, plus every icon size for iOS and macOS.
Yes. Unlimited projects, no per-app fees.
Yes. Add Font… accepts any .ttf, .otf, or .ttc file, Google Fonts included. Imported fonts are copied into StoreCanvas and stay available across every project.
You pay your AI provider directly at their rates, but every image you generate is saved to your AI Library automatically, so you can reuse it on any screen, platform, or project without generating it again.
