If you have a vagus.net research edition tVNS stimulator, you can use this app to connect to it via Bluetooth, configure all stimulation parameters -- frequency, wave form, intensity -- and start/stop stimulation.

If you have the standard edition tVNS stimulator, you can use the app to choose between a number of specially designed stimulation protocols which target specific benefits and issues. Using the app, you can update your device with these different protocols.

The app will automatically recognise which device you have (standard or research) and offer you the options available for your device.
