Bugfixes and Improvements

User reviews

Doesn’t work

The app freezes before I can even use it. I bought a scale at Kohl’s assuming it would be better quality than an Amazon scale but this is not worth the $30 I paid. Disappointed.

Listen to the Reviews

When I started the app everything worked great and I thought the reviews were incorrect. However after 4 weigh ins I decided to link everything to Apple Health so I could use my WW app with my my weigh ins. It was then that I realized I couldn’t verify my email, which means I can’t sync with Apple health and all it says now is that the session is “timed out”. The verify email button does nothing. Now I can’t even weigh in without creating a new user slot and getting rid of my progress. The app is useless.

Worst App Ever

I have never in my life been more frustrated trying to register and use an app in my life. You can’t even verify or reset a password. They have a feedback form that you can fill out but. It even send. It’s impossible to sync to your phone because you can’t verify the account. It’s not that I don’t know what I’m doing. I’ve worked in IT for 15 years. This app is worthless.

Well this stinks

Got the scale and app for Christmas as a gift and bummed it’s not working properly. Constantly says connection timed out. Won’t verify email so I can sync either.

Don’t bother

Waste of time and money
