The Studio
Four small tools for questions that come up in every app project. They run in your browser, store nothing and explain their maths underneath.
App Store and Google Play fee calculator
What you keep from a sale or subscription after VAT and the 15 or 30 percent store commission.
App development cost calculator
Tick the features, pick platforms and a rate, and see an hours and budget range you can question.
ASO character counter for App Store and Google Play
Count app name, subtitle, keyword field and description against the limits, and catch wasted words.
App icon and screenshot sizes, with a live preview
Current icon and store screenshot sizes for iOS and Android, and a preview of your icon in each mask.
