"free" means polluted with ads – Graphing Calculator X84 Review

Banner ads reduce usable screen space. Full screen pop up video ads completely block access. This makes me hate any attempt to use this app. The paid version may be just fine but I suspect the developer will just find more ways to annoy me and blackmail us into paying for basic features or to make more ads go away. Screw you, I bought the real calculator instead.
