Create Interval Training android App

Circuit training/Interval Timer APP I want to create an interval timer as I am frustrated I can’t find something as basic as this. I love this app in the way it sounds and count downs so something similar with the below fields would be perfect. [login to view URL] Below you see I am doing 30 seconds work in 8rounds/stations and I am giving myself 2 seconds to reach the next station. After 8 rounds I get 50 seconds of recovery and account down of 10 Seconds to alert me it is time to repeat the 8 rounds/stations. So in total I am getting 60 Seconds recovery between sets. Each set has 8 stations. Of cause I can always change the fields Below Countdown 10 seconds work 30 seconds Rest 2 seconds Rounds 8 Recovery 50 seconds Repeat 7 times each set should be approx 4.16 with 60 seconds recovery and repeating 7 times gives us a work out time of approx 30 minutes That’s it Please PM if any questions tell me what you can do
