Interval Timer by Jalex

I can set the count down timer for a 30 second workout with a 5 second rest to switch to next floor exercise. Set at 10 reps gives me an exact 5 min. workout time. Just what I need.

Pros & Cons?? Pros: It works great, I use it to buzz every 20 sec, and just set the total workout time, or reps, and set it for 20 sec reps or rounds, Great for doing Circuit Drills & Interval Training, every 20sec you change your exercise, till you finish your total workout time. Cons: Not loud enough & would be nice if it allowed you to change or select different sound preferences, like a whistle sound. I gave it only 4 Stars because I want a whistle loud sound option.

Time adjustment by only UP and DOWN Buttons !!! It takes much time for setup... Please fix this ... It will be the 5 STARRED App !!!
