Amazfit Bip features an astonishing 30+ days of battery life on a single charge, a reflective always-on color touch display, GPS, barometer, geomagnetic sensor, PPG heart rate sensor, 3-axis accelerometer for activity, sports and sleep tracking, while weighing only 1.1 ounces (31 grams). Allows you to receive emails, text messages, calls and app notifications on the watch display. You can track your runs (indoor and outdoor), cycling and other sports with detailed GPS routes and stats.
It is so light that I sleep wearing it and it tracks my sleep. At under 100 USD this is the best money can buy. You can purchase it from Flipkart as it is launched in india. You can custom face the watch and do lots more. The most impressive thing for me as always is battery life. With my usage it easily last me 45 days. There is App for Android and iOS which you can connect via bluethooth and can record your daily habits.
So I hope you get one and enjoy it as much as I am 🙂 loving it.
