I have used this a lot since it was free for meditation and for short naps. The updates have been helpful and address all the issues seen in the negative reviews, so I give it one extra star. It is a nice timer that has the benefits of a calm appearance and a settable preparation time before the timer starts. Im not sure I would have paid for it, but my suggestion would be to offer some options to the bell sound. If your speaker volume is up too loud or if your phone is too close to you the sound can freak you out.
