East to use app. Allows you to save tracked weights and back then up later. Have to edit my review since they added a "pro feature" that they want a yearly cost for. I already bought the pro version years ago in order to avoid ads and the daily pester screens that I see are just as bad as ads in my eyes. I can restore my original glowing review if these pester screens stop and I get the original paid-for pro experience back. A recent update has removed the screens, thankfully!

Graph shows one month's history for the last 30 days (moving month), but only shows yearly history by calendar year, nearly worthless. - - - > Graph has no weekly option. It needs be a moving week. - - - > On the chart, you can tap a data point and a bubble will appear with your weight. The app doesn't compensate for the larger font. Consequently, it chops off the display. And now they let you waste your time by letting you set up your account, THEN make you pay to use it. Pretty lame.

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.
