It is disappointing app when you reach your goals. My target weight is 165Ibs and when I reach 164.8Ibs it still tells me 0.2 Ibs remains to reach my target weight. How come such an important feature of the app is not working still? I commented few years ago for the same issue. Please fix this issue rather than boasting. It is not the app but my weight loss strategy and consistency that helped me lose. The app helps in looking at the trends. If you fix the issue, I will update my rating.

This 'newer' version, designed around advertising, isn't as simple & straight forward as the old one. Sound doesn't work. That said - assuming you 'upgrade' ($40) you can get rid of advertising. It offers a bunch of stuff, not sure of value yet, to help monitor & control weight. I liked the older display better, but I don't 'need' my picture to know it's my info. The graphs & charts may be useful. Not sure yet.

I just purchased pro for the extra logging options, but what a waste. I've had to re-enter data and save multiple times as the app didn't save the 1st time. It only allows muscle in %, and my scale gives it in lbs. I can change my height to inches, but I can't change the measurements from cm. I'd like to be able to track a few other things, but there's no option to add or repurpose.
