You will then need to download the app that works with the Letsfit ID115U, the app is called VeryFitPro and is available from the app store for iOS user and the Google Play Store for Android users.


The Letsfit ID115U has some system requirements of iOS 7.1 and above or Android 4.4 and above.

After 10 minutes you can remove the fitness tracker from the charger.

You will need to ensure you have enabled Bluetooth devices on your smartphone, this will be under your settings section and look for Bluetooth and ensure that it has been enabled.

Search for “ID1115U” and pair the fitness tracker to your device.

Next open the app on your phone and set up an account, you can input details without creating an account, but if you later set up an account it wipes the previous inputted data. So, it’s best to create an account to start off with.
