Brilliant

Absolutely love this app and have been using it for years

PITA

Use to be great till I bought phone Now it sometimes skips body comp or vascular age or both. I have to step on scale 3 or 4 times to get the full reading. Reading may very 2-3 lbs between readings.

Wish I’d found this sooner

Not sure why I didn’t look for an app sooner in this weight loss journey. I went with the “pay to play”, it does offer a few upgrades — but it’s more the frequency that I use the app I’m glad that I did that.

It’s easy to use, provides some basic information (which is really all that I need), and adds to the incentive of tracking weight loss.
