Android Phones
Freestyle Panel is mainly intended for Android phones, which are the most common devices used for this kind of gameplay setup tool. It is generally most relevant for players who use touch controls in shooting or battle royale style games.
Tablets
Android tablets can also support this type of app when the operating system and installation settings allow APK use. Tablet users may benefit from the larger screen when testing layout comfort and swipe distance.
Android TV / Smart TV / TV Box
This app is primarily discussed in a mobile gaming context, so Android TV style devices are not the main focus. Even if installation is technically possible in some cases, the core use case remains touch-based gameplay on mobile hardware.
Fire TV / Firestick
These devices are not the usual target for Freestyle Panel because the app is associated with mobile control adjustment rather than media playback or TV navigation. Compatibility here should be treated as limited and secondary.
PC / emulator if relevant
Some users may test Android APK apps through emulators on PC, but this depends on the emulator, Android version, and input setup. The most natural use case still remains Android mobile devices.
