Simple toolbox.
DevTools is a simple Android dev toolbox I made for my own workflow — Tools like API Tester and a built-in browser in one fast, privacy-first app. It helps me a lot. It might help you too… or at least stop you from opening a laptop.
Why DevTools?

Why DevTools?
A few reasons this toolbox exists in the first place.
Browser + console, on Android
Debugging on a phone shouldn’t feel like a punishment. Console, bookmarks and session save included.
Privacy-first, actually
No tracking, no analytics, no accounts. Your data stays on your device unless you choose to sync.
Tools you can tame
Reorder tools, disable what you don’t use (Settings/About are always there, sorry).
Fast and lightweight
Around 17MB, DevTools stays snappy with zero ads and minimal battery impact.
