A faster reference for Android development
You lose a surprising amount of time looking up the same things: which API level shipped with which Android version, what a permission actually unlocks, or the exact keep rule that stops R8 from stripping a class. These tools put that reference one click away and add interactive builders for the fiddly bits, so you can drop an APK to inspect its manifest, generate a deep link, or convert a vector drawable without leaving the page.
Everything runs locally in your browser, so the APKs you inspect and the rules you generate never leave your device. The site installs as a Progressive Web App too, which means your reference stays available offline whenever you need it.
