In 99% of the cases, this happens because your moonbird is still in travel mode.
Travel mode makes moonbird less sensitive, so it only starts when it detects a real heartbeat. If your hands are cold or placement isn’t perfect, it might not respond.
To fix this:
Open the app
Go to Settings
Toggle travel mode OFF to return to regular sensitivity
Close app and wait 30 seconds
Still not working? Try the following:
Make sure the app is closed
Moonbird can’t start in standalone mode if it’s still connected to the app. Fully close the app and wait 30 seconds
Place your thumb gently on the sensor, not too hard, not too soft
Wait 5 seconds after placing your thumb, that’s how long it takes to begin
Once these are sorted, your moonbird should start the exercise like usual. Still stuck? Just drop us a message, we’ll help you breathe easy again.
