Review on 📱 Advanced Smart Watch for Android and iOS Phones: Men and Women Compatible with Samsung and iPhone, Monitoring Sleep, Heart Rate, and Health, with Activity Tracker and Pedometer, Counting Steps and Calories by Gelin Battle

- its fitness-oriented function, meaning different modes such as step counting, sleep, heart rate, workouts (cycling, walking, etc.). Although it gives you a preview of your messages, you cannot reply to them. It also gives you a preview of who is calling. The design is very neat. The battery life is amazing. I charged it last week and it's still alive. Well I haven't really used it much, but it's still amazing. If you use it that often, one charge is enough for 2 days. It comes with a charger and charges quickly too.
