A free program for Android, by drsv.

The Free World BMX app combines tricks to increase your score and there are no guidelines or time restrictions. With this app, you can use a variety of tools and products to adjust your parameters (speed, height, rotations). Your tricks will also receive comprehensive scores from the app based on how awesome they are. In addition to your height in the air, speed, number of spins, and number of combos, it also considers your ability to land, how well you know the park, and how challenging the tricks are.

Just a heads up, on certain platforms, a game might not run as intended. And this app does not support restoring or syncing data.
