Fitness Bands – Fitbit Charge 4 + Waves Tracker App (tutorial)

In this blog post, we will talk about how to get WavesTracker going with a Fitbit Charge 4, Fitness Band. And to do it, some extra configuration will be required as some features from the Fitbit Charge 4 come disabled by default.

To download the mobile app use the Play Store.

Let’s do some fine-tuning to get the watch recording your data with more accuracy and frequency; on your Fitbit Charge 4 watch do the following below:

  1. Go to Settings > GPS Settings
  2. GPS Mode: “Built-in GPS”
  3. GLONASS: “ON”
  4. GPS Low Power Mode: “OFF”

In addition to the above, configure the WavesTracker app to be less sensitive to start with, here is how to do that; on the Waves Tracker app do the following below:

  1. Go to “Settings” > App Settings (section).
  2. [Min Speed: 8] / [Max Speed: 55] / [Distance: 18]

*Note: These settings can later be fine-tuned further until you find the sweet spot where it detects most waves for your surf break.

You are all done! When you are at the beach about to go surfing do the following:

1. You will use the watch’s activity tracker to record your surf session using the “Outdoor Workout” exercise/activity type.
2. When you are done, stop recording (at the beach), your watch will sync with its companion app automatically.

*Note: It is important to wear your watch over your wetsuit/rash vest, this simple trick greatly increases the GPS signal quality and the final result.

Lastly, you will use our web app to upload your surf session.

  1. Export the TCX of your activity from the Watch companion app.
  2. Go to and log in using the same provider as in the mobile app.
  3. Tap Upload, and select the TCX file.

Your surf session is then processed immediately and you will be able to see it in your feed and history on the mobile app.

Fitbit Charge 4 is the first fitness band that we have tested, other fitness bands do exist in the market and we believe that the app should work well with them too as long as you can export the data collected and import it into Waves Tracker. Our app should be able to detect the waves that you have surfed.

Thanks for reading and until next time.
