I’ve been using the Healy now for about two years. The Healy 2 app is a definite improvement from the old app, but it falls short, when increasing or decreasing the frequency strength.
For example: if the app could be made as to when you push to increase, you would just hold down, and it would increase as much as you want, and the same for decreasing as opposed to constantly keep tapping and typing and tapping. I would like to see for people who use the coil to have the ability to preset the frequency level of choice. That will be a real nice feature.
