Very easy to use, put in batteries, step on scale, shows the weight. If you want any more information you need to pair it with the phone via Bluetooth via the app. The app isn't brilliant, took 5 minutes to pair and then removed users (I created a second user) - came back 2 minutes later though, so a bit confusing. Seems okay now though, so overall pretty good. Only took a second to calibrate when I first stepped on it. I'd recommend this scale for it's simplicity in basic use, the 'report' it gives you is pretty detailed as well via the app.
