- Simple and easy to use dashboard-like UI
- Designed to run 24/7 (memory efficient, reconnects automatically)

Friends! This app was created for my own needs in my free from work time. I'm not making money from it. It doesn't contain advertisements, in-app purchases or any hidden cost, so please be considerate when rate the app.
Positive ratings are appreciated! The app will evolve depending on your ratings, because I'm investing my free time in the app.
