Articles de fond sur le design et la conversion des carrousels App Store. Mis à jour au fil des livraisons.
The four accepted Mac App Store screenshot sizes (1280×800 to 2880×1800, all 16:10), how to capture them on macOS, and how to frame them. Honest about where most tools leave a gap.
A metadata rejection is a listing fix, not a build fix. What triggers 2.3.3, 2.3.7, 4.3 and 5.2.1, plus the before/after wording that clears each one.
Side-by-side workflow comparison. Honest about where each one beats the other.
Flutter has no first-party store-screenshot pipeline. The honest options — integration_test capture, golden tests, Fastlane/Codemagic — with real code, plus where marketing composition and 50-language localization fit.
One is indexed and locked to your app version; the other is not indexed and editable anytime. Which is which, and where your keywords actually belong.
Apple has a hidden keyword field; Google Play indexes your whole description. A field-by-field map of where keywords count on each store.
Apple's hidden 100-character keyword field, filled properly: the comma rules, what not to repeat, and the secondary-locale trick that roughly doubles your indexable terms.
EAS Submit uploads your binary but does not generate or manage store screenshots. The honest, command-by-command workflow for Expo developers — capture, automate, compose, localize.
When the 30-second video pays off vs when static screenshots win. Category-by-category.
The exact pixel sizes App Store Connect accepts per display class, why the 6.5"/6.9" mismatch triggers the error, and how to re-export at the right size without upscaling.
React Native has no first-party screenshot pipeline. The honest options — Fastlane, Detox, manual capture — with real commands, plus where the marketing composition and localization step fits.
Browser-native workflow for indie devs and small teams. What you skip when you skip Photoshop.
What we measured across the top 100 App Store carousels — caption length, dominant colors, device-tilt direction, text placement.
Honest take on which performs better, when, and why the answer is more nuanced than "dark mode always wins".
Caption-writing rules that hold up across categories — length, structure, verb choice, and the captions to avoid.
The practical workflow for shipping screenshots in every locale Apple accepts — what to automate, what to review by hand.
The structural design decisions in any high-performing carousel — caption position, device tilt, palette, continuity. With Headspace as a worked example.
A hands-on walk-through from blank canvas to App Store-ready 1290 × 2796 PNG, using Mokbi. Plus what to do for iPhone 16 Pro Max submissions.
What works in the App Store carousel right now — patterns from top-100 apps, the formats Apple keeps pushing, and where conversion gains have moved since 2024.
