Save your money. Spend it on Buddhify instead.
This is not a good product. In-app purchases aren't reasonable, as you're paying for basic functions like adjusting the time interval. You could get a free Pomodoro time keeping app and it has more usefulness than this. The distraction tapping function is a cool idea, but I wish you could use it with a lock screen since it's a bit of a drain on the battery to keep your phone on for long sessions. Not impressed. I made a poor purchasing decision with this as I based my decision on Internet 'word of mouth'. I decided to take a chance despite no reviews, and I wish I could've saved myself a few dollars. Until the developers come up with reasonable pricing strategy with a better, or smarter, functioning interface...I would suggest staying clear of this app.
