Android may take a little bit longer to pair with your bottle. For Android devices running 6.0+ you must have location services enables and allow Hidrate Spark to use them in order to pair and sync with your bottle via Bluetooth.
If you have troubles pairing during set up, press skip and continue to create your account. Then go to your profile within the app and click the "add bottle" button.
If you are unable to pair or get an error please restart your phone. This will most likely fix this issue where it is not picking up the bluetooth. Once your phone has restarted go to your profile within the app and click the "add bottle" button.
We are continuously making updates to our apps to improve syncing and pairing reliability so be sure to always be on the latest version of the app.
