I bought it as an insignificant gift for my wife, so he went in: she doesn’t even take it off at night. We made friends with the iPhone, notifications come, everything is in 2022, there are no hieroglyphs (I read everything here from that I had concerns about this). The charge holds for a long time (we left the screen settings by default). This is you first watch with notifications from your phone. I am not an athlete and I have nothing to say about any fitness functions)
