Markel For Heisman

A must-have for the season! Even as part of the Beta testing, I know this app is going to help me tremendously. I love being able to switch between several leagues seamlessly with the ability to see the best start/sir combinations along with who would be best to pick up off the waiver wire to put in my lineup.



This app is fast, smooth syncs, and provides excellent information for planning not only this week, but RoS as well.

Great App


My previous review was wrong. 4for4 has fixed the bugs in the app and now the app is amazing! Thank you for your excellent customer service 4for4 developers!!
