Guides

Practical, up-to-date guides for getting an app through App Store and Google Play review — written to answer the questions developers actually search for, with the exact sizes and rules in one place.

How we keep these guides accurate

Store requirements change every year — new iPhone screen sizes, new Android API levels, new privacy rules. Each guide shows the date it was last checked against Apple's and Google's official documentation. If you spot something out of date, tell us and we'll update it.

Every guide links to a free AppNimbus tool that does the work for you, so you can go straight from reading the rules to producing the files.
