Download the MysteryVibe app from the Apple App Store or Google Play Store. Open the app and enable Bluetooth on your phone. Note that Android requires location permission for the Bluetooth functionality to work - this is an internal Android step, and your location is not used or tracked by the app. In the app, select ‘Tenuto 2’ and then ‘Tap to Connect’. When it prompts you to connect with Tenuto 2, press and hold the left arrow button for 2 seconds. Tenuto 2 will vibrate twice indicating it’s ready to connect and the app will then be connected with Tenuto 2.
