In HummCar you do the humming and the car drives. You control how fast you drive with your humming sound (pitch) as the steering is done by a robot.
If you drive too fast then you might drive off the road. If you drive too slow you might not jump over the cliff. You can also change gears with your voice. See the app-preview video to learn more.
HummCar works best on devices with a separate ear-speaker i.e. iPhones, because the driving music can play from ear-speaker without interfering with the microphone input. Runs on iPhones starting from 5S or newer, dont load onto older phones even if that is possible.
