Review on 🕰️ Amazfit GTR 42mm Smartwatch - GPS+Glonass, Heart Rate Monitor, Activity Tracker, 12-Sport Modes, Moonlight White, 10-Day Battery Life by Chun Hee Kim ᠌

For just hours with notifications, they are not very bad. Heart rate monitor: It turns out that plants have a pulse and a chipboard table has it, for example, it was hard for me to eat an orange, in which they showed a pulse of about 70. More or less adequately measure the pulse in the hall or at home, on the street the difference with a chest heart rate monitor can be two times. Dream: May be wrong for a couple of hours, compared to huawei. The sleep data from amazfit seems to be quite approximate. Sensors: There is no navigation, no trackback, no altimeter calibration, GPS only works in training mode for track recording and speed measurement and in altitude measurement mode. Heart rate monitor - see above. The only sensor that is used by the firmware by more than 5% is the G-sensor, steps are counted on it and it is responsible for turning on the screen, it should be noted that it works very well, the screen turning algorithm is such that sometimes you even forget that you have an OLED watch , they do not need to be shaken, twisted and raised 3 times. Looked at the screen, it lit up, perfect job. Interface: Everything is pretty smooth, nothing slows down, with custom dials sometimes the transition from the dial or to the dial from other screens slows down, with stock there are no brakes at all, everything is smooth and smooth. Screen: For OLED, the screen is good, the picture quality is no worse and no better than Apple, Samsung and Huawei (although all screens are different). The adequacy of automatic brightness control is 99%, i. E. in 1% of cases, auto-adjustment is wrong, and it is wrong so that in the dark you can shine like a flashlight (but this happens extremely rarely). Belt: A cool solution for a rubber-like belt is to glue a strip under the skin. Total: Notifications come, everything is quite convenient, they do not look bad. If you take it for sports, then even in an approximate comparison with suunto, polar does not go (like all other near-sport watches). For daily wear - in terms of actually used functions (except for payments) - well, about the same as the rest (apple, samsung, huawei .) only autonomy is 3 weeks.
