WearinOS

The app need an optimization, and the watch also need a makeover, right now it's sluggish when going thru the menus, and you have to wait for every txt line to roll.. The screen is not sized either for its software, please adjust the menus so it looks better.. And remove the static images when taking measurements etc, and put actual readings instead.. And please make the data transfer secured, as of now it is not safe! I have the hello watch 2 also, and that one provides all this, and updates

Disconnects every few minutes. If your phone is on the charger your vape will update every 1% that your battery charges. You cannot actually make calls or texts even though the app allows you to add contacts and everything you set up(wallpaper, ect) all reset to the factory settings as soon as your vape & phone disconnect(usually happens within 20 minutes).

bugs. keeps crashing. doesn't update oil/puff % on app. no real way to know your vape is going to die until you go for a puff and it doesn't hit. it's a pretty cool idea when everything is set up and operating correctly. I probably wouldn't buy this product again.
