The reviewed GPL-3.0 FOSS edition has a usable free core for physical-key remapping and actions. The provider explicitly offers certain advanced triggers and special features as paid add-ons; do not label the entire product feature set free. F-Droid also flags promotion of the paid Play version. This selection covers the available FOSS package, not a paid extension or every Button Mapper Pro feature. Some actions need accessibility, keyboard, Shizuku, ADB or root support and can depend on Android version and device hardware; basic remapping does not require buying a server or API.
