I just found this app yesterday. So far its great. It has
- Quick and easy food logging
- Access to our library of hundreds of educational articles and challenges — all intelligently assigned by the Coach.
- Reminders and Notifications.
- Pedometer and GPS tracking.
- Group Support and more.
You can go Pro for around $10 a month to add a recipe library, waist measurement tracking and more challenges. The more you do the more you level! You gain levels the closer you get to your goal which I find appealing.
