Songbird is an exercise-bike controlled fitness game that keeps you motivated to play.

It works with your smartphone and any exercise bike. Just strap the required Songbird cadence sensor (available at https://www.songbirdgame.com) to your pedal crank arm and start the app!

Pilot five da Vinci-style pedal-powered flying machines to bomb cities, battle in mid-air, or build cities. Hunt for convoys carrying treasure. Build an empire by attacking cities or capturing and delivering pigeons for diplomacy. Enter city-to-city checkpoint races. With Songbird, you'll want to exercise every day because there's always something new to try. And with its procedurally generated, endless 3D terrain with nine biomes, you can fly forever in any direction and never run out of new things to see.

Ready for something different? Songbird can be played start-to-finish in VR mode using Google Cardboard. Or keep it simple and play all the way through in casual mode with one-handed or two-handed play.

In addition to an addictive video game, Songbird is also an all-inclusive fitness manager working on the principle of calories-in/calories-out. The game automatically counts and logs the calories you burn while playing, lets you log the calories you consume in the main menu, and tells you how many calories you can consume at any given time to stay on track. It calculates any calorie deficit you should be targeting to meet your goals using a modified Harris–Benedict equation (with override).

NOTE: A Songbird cadence sensor is required to control the game with your exercise bike. It can be purchased at https://www.songbirdgame.com.
