a-rival

A-rival is a fitness app that works in conjunction with a portable fitness tracker and is designed to monitor your health and physical activity. The app lets you track all the information you want down to the last detail, including your sleeping habits, weight fluctuations, calories burned, blood oxygen level, and heart rate.

To start using A-rival, you'll have to create a profile with lots of information about your body, your habits, and your objectives. After that, you can connect the app to a device that tracks your physical activity, and it will update automatically with all the pertinent information.

This app will help you understand and monitor your physical activity to help you lose weight or feel healthier. With the data you provide, A-rival will calculate how much exercise you need on a daily basis to get healthy and reach your goals.

A-rival is a great app for athletes or anyone who wants to exercise more. It has a lot of the same features as Google Fit and Xiaomi's MiFit.
