Yes, it's a simple basic timer, at least as far as I explored it. It seems easy to use--I tried the free version. However, my issue is with the alarm sound. It rings with three beats of a dissonant gentle gong sound.Even with the free version, I feel that sounds are a very personal matter & can deeply affect one's enjoyment or aversion to its use. You might consider making certain features available:1. A sound gallery for alarm sounds.2. The option of using two different sounds for end of rest & end of exercise.3. The option of determining how many times the alarm sounds in each function, resting & exercising. For instance, I might want it to sound a bell ding only once at the end of the rest period & then sound only once with a tweet sound at the end of the exercise period. Or, sound a bell ding once at the end of the rest period, then a bell ding twice or three times at the end of the exercise period, etc.Thank you for the opportunity to try out your app. Good luck.
