I've read about the pact app before but have just downloaded it. I wanted to get some feedback before I enter my credit card details. Did it really keep you motivated?
For those who don't know about the app, you make a weekly pact regarding your fitness goals, e.g. 3 workouts. You get paid a small amount per workout (around $1-1.50 I think) but if you don't do all of your workouts in a week, you get fined an amount you've decided on ($5-50). You're paid when you meet your commitments by the people who don't meet theirs.
