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.

I'd give it more stars if: 1. I could manually enter dates and weight without having to use the rolling scroll bar. 2. My data had saved after I had to hard reset my my phone. I am having to re enter 3 years of weight measurement on memory. It's a great and simple app that I have been using since 2017 and 100 pounds lost. But no backup data function sucks.
