I bought and installed this today, really wanted to have a good sync with Apple Health. If you are currently syncing your Fitbit with Myfitnesspal I would maybe consider not buying this, I had those two apps synced with great results, but since getting this app, the sync between the two has not worked or worked as it had. Additionally, Ive noticed slight (very slight) differences in weight amounts, so it appears not to have synced that data exactly. Finally, it takes a while for sync to work, so you probably wont see it updated for awhile. Also have not gotten great response in terms of support. I feel like I wasted $2.99 right now.
