You can choose the sensitivity of your moonbird:
The “normal mode” is sensitive. You can activate your moonbird smoothly, no matter your skin type or blood flow.
The “travel mode” is less sensitive. The moonbird is only activated when the sensor detects a real heartbeat (instead of just “dark”). This way you can take your moonbird on the move without it going off in your bag.
You can switch between the two modes yourself. To do so:
Open the moonbird app
Go to the blue oval icon in the upper right corner where your battery percentage is displayed
switch the toggle between “travel mode on” on and off to adjust the sensitivity of your sensor.
Important: if your moonbird doesn’t seem to start in standalone mode, it could be because travel mode is still enabled. Try switching back to normal mode to see if that solves it.
