Minus a million.
1. The most important thing is that it counts the steps incorrectly. More precisely, he considers according to the principle: you stand still and wave your hand, which means you are walking; you walk without moving your hand, you stand still. Movement in several steps does not track at all. Often gives out messages that you need to move, because. You see, I stayed up in place, although I had just walked. The Samsung smartphone shows up to a thousand steps more per day, and with it I walk MUCH less than in one watch.
2. Notifications. You can only read SMS and messages from instant messengers and applications, and then only a certain number of characters, the rest are not displayed. Emoji, stickers, pictures are also not displayed. Voice messages cannot be heard. For email messages, only the email headers are displayed.
3. Timer. You can set only for a certain number of minutes: 1, 2, 5, 15, 30. The rest of the time is obviously not needed.
4. Definition of sleep. Thinks you're asleep when you're just lying down and reading a book.
5. Determination of the oxygen level. It's as you wish. I had from 92% (apparently, severe pneumonia broke out at that moment) to 100% (and here, apparently, after 5 minutes I was cured, fantastic!).
6. Measurement of pulse. 100 beats per minute, after a second 80, after 2 seconds 90. Apparently, the flattening is not childish))), if so, the pulse jumps)))
7. Not enough normal functional screens
