1. Especially in a recession.This is the first time I've ever rated an app!! If you, like me, have reached that mythical point where you're finally ready to make a change in your life, this is a no-pressure, extremely simple app with no fancy bells or whistles needed to accomplish what you're setting out to do.

2. I just want something to tell me when to start and stop running (the spirit of the program), and I'm not finding it here.I previously used this app years ago and absolutely loved it.

3. I really want to purchase the full version to support the devs, but can not bring myself to do it until this is addressed.I use the free app, and have for years.

4. First when I began running to train myself to go a distance and various other times here or there to help me train on increasing my speed.

5. C25K transition to C2 13.1 has got my half marathon ready every time! LOVE THIS APP!The workout regimine is awesome, my wife and I use it on alternate days.

6. Usually when I use it, I can shrink the window into the background and use my phone for other things (I have music playing and I read while on treadmill) and open it back up with no issues.

7. I had some extra Google store credit and decided I wanted to buy the distance tracking feature.

8. I understand the theory behind it, but in this day and age where people are valuing privacy, there should be an option to disable tracking and simply use the timer.

9. Now when I shrink it and open it, it either closes out or restarts.Now requires GPS location tracking.

10. Unfortunately, instead of getting GPS tracking, you get a loose distance approximation based off of number of strides.

11. The user interface is nice and friendly, but I can't stress how awful the tracking system is.
