Dr.warm

I am using this with the heated insoles that Dr Warm sells on Amazon. Connectivity is easy but you need the soles close to phone. And I can access the upper settings easy but the bottom setting is for temperature of the insoles. This is the primary reason to use the app - to set the temp. And it is hidden under the menu bar at bottom of app. I cannot access the slider to change the setting.

Does not work with the liners I bought from them even though all there products use the same kind of battery
