### ⭐⭐⭐⭐ needs to be connected to smartphone to use any features
*by M***C on January 16, 2026*

yes you need a smartpone to use this, if like me anyone else was wanting to get this hoping to just use the pedometer and heart rate features without connecting to a smart phone because they dont have one, the first screen to that pops up on this is a QR code to download the app and you cannot move forward until you do that. i get that this may seem obvious being it is a smart watch lol but i asked the silly 'ai' question thing on amazon if i could use this for the pedometer without connecting to a phone and it said that i could but i can not : )
