Just a quick note. The OS was not the issue. Pit Pal supports anything >= Android 2.2
For those interested:
Issue was because one of the pit pal features allows you to take pictures of your food and tie them to your cook log. Because of this, the app requires the camera feature and for some odd reason, some phones & tablets (galaxy proclaim, nexus 7 for example) are not recognized having that camera feature on the app store so it was showing as incompatible.
So I made the camera feature "not required" so it will be able to download properly and then doing an internal check for the camera availbility before snapping the photo.
