Fitness Tracker Free is a general purpose fitness tracker app.
It is totally free with no ads and it does not monetize or transmit user data outside the device.
I created the app as a school project with the intention of making a fast, light, and private fitness tracking and journaling tool.
More features and bug fixes will be added over time.
The Android version supports Bluetooth and ANT+ heart rate and bike speed sensors.
It is available on Android via Google Play and coming soon to iOS.
