App worked only for couple days,watch is useless without the app, I regret buying the trash now. 2/4/2022 This is the most useless device I have ever owned. I deleted and re-downloaded the app, can't even use my username and PW anymore, it won't login in the app, works on the website though. Watch is all acting up, not recording my walk & workout, keep messing up the clock. I wish I can get my money back. Will update more in a week.
