This is a simulator, not a game. The simulator enables you to practice your FPV racing/freestyle and LOS flying skills on your android device.
This simulator requires a powerful device.
You will get best performance if selecting Low Screen Resolution and Lowest Graphics Quality on the main menu. Also, if possible activate "Performance Mode" or similar in your phone settings to get the best performance.

(There is a free version of the original FPV Freerider app that you can try to see if it works on your setup. If the original FPV Freerider app works on your device, chances are pretty good that FPV Freerider Recharged will work too. Recharged is more demanding though).

Supports self-leveling and acro mode, as well as 3D mode (for inverted flying).
Custom settings for input rates, camera and physics.
Google Cardboard side-by-side VR view option.
Touchscreen controls support mode 1, 2, 3 and 4. Mode 2 is default.

You can use touchscreen controls to fly, but flying a racequad with touchscreen controls is very hard. Using a good physical controller (such as an RC radio connected via USB OTG) is highly recommended. There are a lot of videos on youtube that shows how to connect an RC transmitter to FPV Freerider. You can also find more info in the manual, there is a link at the end of this text.

Physical controllers are configurable between mode 1,2,3 and 4 during the Calibrate Controller procedure.
Controllers that have been successfully used include FrSKY Taranis, Spektrum, Devo, DJI FPV, Turnigy, Flysky, Jumper, Radiomaster, Eachine, Detrum, Graupner and Futaba RC radios, Realflight and Esky USB Controllers, Logitech, Moga, Xbox and Playstation gamepads.

This version of FPV Freerider Recharged is adapted to android devices. In order to keep the file size low and performance up, it does not contain the usual built-in levels of the desktop version. Instead it has some adjusted/previously unreleased levels more suitable for mobile devices.
The full level editor is included. The levels are fully compatible with the desktop version of Recharged.

You can use the touchscreen to create and edit levels. Levels can be saved and loaded locally on your device.
It can be difficult to make precise editing on a small screen - for extensive editing it is recommended to use a USB/bluetooth mouse (and keyboard). An even better alternative is to use the desktop version to create your levels and then simply copy them to the correct folder on your android device.
The correct folder is usually found at
"/storage/emulated/0/Android/data/com.Freeride.FreeriderRecharged/files"
(or "Internal Storage/Android/Data/com.Freeride.FreeriderRecharged/files/")
