If two people are using it, make sure you BOTH have it connected to your phone or all weigh-ins will appear on the first phone you connect.
This is so much better than manually entering my weight each day. Don't even have to have the phone with me in the bathroom (sooooo much easier), or using whiteboard markers to jot it on the shower glass.
Also unlike the last two scales, when you lean on different angles it only goes out by 0.2kg, where other scales have been out by up to 5kg doing this... is exactly the same weight as my doctor's professional scales... perfect.
Highly recommend this...
