Installing the doppel app
The doppel app is compatible with Android (5 or later) iOS (9 or later).
Charge your doppel
doppel needs to be charged for 2 hours before setting up for the first time.
Pair with the app
Turn on your phone's Bluetooth, open the app and follow the setup sequence to pair your doppel and begin creating your own, personalized rhythms.
The doppel app will create pairs of personalized preset rhythms just for you, each with a high beat and a low beat. Follow the steps to take your resting heart rate so that the app can suggest rhythms based on your physiology.
Set your pace
Take time to find rhythms that work for you and try them out in different situations. Save your favorites on the app.
Wearing your doppel
doppel should be worn with the metal base pressed against the inside of your wrist, on the point where you would expect to feel your pulse.
You can wear your doppel on either wrist.
Adjust the strap to ensure a snug but comfortable fit
To adjust the strap size, change the position of the popper before putting doppel on. Choose the hole you want for a snug but comfortable fit, then push the strap down hard over the round top of the popper.
To make sure the popper is secure, push the strap around the popper edge, and check the strap is flat. You can change the position as many times as you need.
And don’t worry, there is a spare popper in the box if you lose the first one.
