The app no longer works. I gave it 5 stars before and used it religiously every day, while supporting the devs as often as possible. Now when I try to start a new session nothing happens. There's a countdown in the notification bar but the app itself doesn't work. The big timer in the app is frozen and I'm able to use my phone freely. A week ago or so I couldn't complete any session since the timer and the session itself would just reset at some point, without me knowing. Highly disappointed
