tracktor 🕵️

A GitHub user tracking app, inspired from below GIF 🤷

Can be considered as a demo project to showcase MVVM with latest android development tools

Dark Mode Available 🌙

Usage 📱

There's this person. You admire him a lot because he's a very passionate programmer. You press the follow button but you're not satisfied with GitHub's feed, since it shows only minimal information about the person you follow. Then this app is for you 😉

How to use? 🤔

Install the latest APK from releases 📥
Add him/her to the list by entering the GitHub username
Done 👍

Now you can see whatever he does 😜
