The Apple Watch has grown from a niche device into an essential health and fitness companion for many satisfied users. The new year is a great time to take advantage of all of the features the watch has to offer such as step tracking and heart rate monitoring, and those features are even more useful when you connect them to a fitness app.

In this guide, we’ll be covering MyFitnessPal and LoseIt – two of the most popular free fitness apps on the market. However, Apple Watch does integrate with a huge variety of these trackers and you’ll find the process is about the same with some minor tweaks.

    Basically, the process in almost every case involves heading into the fitness app, connecting it to Apple Health, and enabling permissions to allow the app to read and write data to Apple Health.

    Let’s walk through the process on how to sync Apple Watch to your Fitness app using the example apps above.
