Microsoft OneNote- Slim your app below 200 MB (it's 434 MB)Medium
At 434 MB, iPhones ask before downloading on mobile data, and many people give up.
- → Find what's big: images, PDFs, fonts and videos bundled with the app are the usual cause.
- → Compress images and PDFs, drop unused assets, and download large content after install (from your own server, or Apple's On-Demand Resources).
- → Flutter: build with --split-debug-info and --obfuscate (below) so debug symbols stay out of the app.
Flutter buildflutter build ipa --release --split-debug-info=build/debug-info --obfuscate
Prompt for Claude Code or CursorThis iOS app is 434 MB on the App Store; above 200 MB iPhones ask before downloading it on mobile data. List the 15 largest files bundled into the app (assets, PDFs, images, fonts, frameworks) with their sizes, suggest how to shrink each one (compression, removing unused files, downloading after install), and make the safe changes: compress images losslessly and remove assets nothing references. Don't change app behaviour, then tell me the new estimated size.

iPhone Duo is on sale now, and Apple added a screenshot size for it. From April 2027, Apple requires them for every app and game submitted, so your next update after that can't go out without them. The public App Store page doesn't show whether Microsoft OneNote has them yet.
- → Run your app in the iPhone Duo simulator in Xcode, on both the outer display and the inner (unfolded) one, and fix any screen that stretches or leaves empty bars.
- → Take screenshots at 1398 × 2034 pixels for the outer display and 2007 × 2853 pixels for the inner one (landscape works too: 2034 × 1398 and 2853 × 2007).
- → In App Store Connect, open your next version, choose iPhone Duo under Previews and Screenshots, upload them, and submit the version. They go live with it.
- → Already added them? Then you're set.
