The ROADTEC Fitness Tracker works well for my daily walks. It has health monitoring and indicates heart rate and sleep duration. It also has a remote camera, pedometer, calories burnt, slepp monitor and alarm clock reminder. It is waterproof and can be used in the rain or while washing hands but cannot be used for swimming or in the shower. First I downloaded the app. I paired it with bluetooth on my Iphone. The fitness tracker is charged on the USB port on my computer in 1.5 hours and the charge lasts 5-10 days. There is a 12 month warranty on the ROADTEC Fitness Tracker. #RankBoosterReview ii, Sponsored iii, ROaDteC Fitnes Tracker https://www.amazon.com/gp/product/B07DVSWTWH/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1
