Blue Connection app for iPhone and iPad

Blue Connection will alert you if you begin to move away from your phone when wearing your Fitbit by making a sound. Conversely it will also alert you if you leave your Fitbit behind. It uses a trained machine learning model to predict when your phone and Fitbit are becoming separated. The data fed into this model is never uploaded, and it never leaves your phone.

If the app is notifying too frequently, please let us know via Twitter, and let us know which phone and Fitbit models you are using, we have no metrics built into the application so we only have access to the information provided by you.

Naturally you must have the Fitbit application installed on your phone, and you should have an active Fitbit.

Features:
- Records the last location where your Fitbit and phone were in proximity
- Configurable sensitivity in settings
- Independent DND mode configurable in settings
- Disable switch also in settings if it is too active

Privacy & Permissions:
- We ask for GPS data for the model as well as for detecting "significant location change"
- We need bluetooth to be able to connect to your Fitbit
