Mala was intended to be worn as a Leaf accessory and during your meditation practices, however, we do not recommend constantly wearing your Leaf attached to the Mala, especially during activity due to the length of the Mala necklace. Make sure your Mala is double wrapped, and that you have the necklace setting in the Bellabeat app.
In case of inaccuracy, please try setting your placement as a bracelet and wearing your Leaf like that for a few days to see if the accuracy will improve.
