Awful

I use this with an iFit Classic.
The app is bulky and unintuitive.
The worst is that there is no way to enter custom food data. If its not in the database, too bad. You can enter calories from the watch, but only in groups of 50 cals at a time.
Avoid the watch and app, there are much better on the market.
