Treadmill Interval Running

Works perfectly for my 10+ year old treadmill. What more do you need?

I have an old ProForm 10.5 QM treadmill that uses iFits chirp control system and this app works well with it. I've designed and used a few programs and almost all stages achieved the expected speed and incline exactly including auto start and stop. A few chirps occasionally get ignored (about 10%), not sure why. A few gripes. There appears to be no way to backup or export / import your own workouts so you can copy same from say your iPhone to iPad. You can delete unwanted workouts by swiping left on load selection but help does not explain this.

...room for improvement: 1. Minimum interval is 1/2 mile but many training plans have 1/4 mile intervals. 2. Needs to show speed/pace - I don't know what the speed of a 7:10 pace is, but that's what I need to put in.

Updated app and had to put on another device since they went to IOS 6 and it works very good, only missed 1 "chirp". Puts new life into an older treadmill ! Have the older version on an older device and of all the times I have used it, that one has never missed a chirp !
