To make sure you have a great experience with the app, we do not recommend using Bluetooth headphones in Simply Piano. Bluetooth does come with delays and these vary across different headphones. We are working on supporting Bluetooth headphones so you'll have a great experience with them as well soon. In the meantime, we recommend connecting your phone/tablet to wired headphones.
While we do not support Bluetooth MIDI in Simply Piano, many of our learners successfully connect to Simply Piano with it. If you have trouble connecting to Simply Piano with Bluetooth MIDI, try connecting to another app that does support it (for example GarageBand) and then open Simply Piano.
