Best Pep Tracker/Calc

So far this has been the best app I’ve found. For this one simple reason. The ease and use of the pep calculator! You can easily find out how many units to use and get proper dosing! In the beginning this is so important! The library, tracking and other features are great as well. Can’t wait to see where the app goes and the community it builds!
