First I must say the C25K app is amazing - I am starting Week 2 and loving it, and looking forward to my first full 5k run!
I have a question about functionality - perhaps I am doing something wrong. I am using the C25K Pro app (version 3.2) in an iPhone 5, and I find I need to leave the app running and holding the phone in my hand (without me or anything touching the screen anywhere) in order for the voice prompts to work and the timing to be correct for each walk and run segment. This is kind of a pain because I would like to be able to open the app, select the day I am currently doing to start the app counting down, push the iPhone lock button and pop the phone in my pocket and off I would go eagerly listening for the voice prompts to switch between walking & running (which when it works is brilliant, but when it does not work - see my next sentence - it is wholly troubling since I am counting on the app to coach me as I cannot currently run much longer than the expected 60 seconds & if I need to look at the countdown timer while running it defeats the utility of the app). If I go through the steps as I outlined in the last sentence and lock the phone and put it in my pocket I find the timing between segments is not always accurate (i.e.the timing sometimes works counting down correctly, while other times it does not as the time stops until I take the phone out of my pocket and open the app again and the voice prompts sometimes occur and sometimes do not - therefore leading me to not trust the app). The only way I have found to have the countedown and voice prompt both work properly is to hold the phone with the app running (and lock screen setting disabled in C25K app settings).
Like I said maybe I misunderstand how the app is supposed to work. Do I need to leave the app running as the currently displayed app so I can see the countdown timer and not touch the screen while running to have it work properly? Or, should I be able to fire up the app, lock the phone and pop it in my pocket and expect it do continue working properly (which is what I would like - kind of the way MyFitnessPal works).
By the way I have tried various combinations of playing my music through the C25K app and not, and music does not seem to be the variable that causes the problem. The variable has something to do with the iPhone lock and the screen staying on or not with C25K running in the foreground.
Your thoughts and help would be appreciated
