Just took a look at the latest reward system for both Feature Point and FreeMyApp.
3000 FeaturePoint points
- USD5 worth of Paypal
6000 FeaturePoint points
- USD10 worth of Paypal/iTunes
3000 FreeMyApp points
- USD10 worth of iTunes credit
So if you want iTunes credit, stick with FreeMyApp. If you want PayPal it doesn't look like there is an option. Will hv to stick with FeaturePoints
Update 4 Dec 2013: Lower value coupons/cashout from FeaturePoint seems to run out earlier and faster. You would need to wait for it to come back before being able to trade your points.
