WallPanel substitute to Kiosk browser

I’ve recently discover a free app:

WallPanel -

This app can successfully substitute Kiosk browser. Sharptools is perfectly running on it. I have Amazon HD8 and for each Alexa command the display went black until I’ve touch it. With this app , after showing Alexa home control screen, the SharpTools dashboard displayed back again. Same as in Kiosk browser.
