Strap your phone on a thigh with a sports armband holster with Velcro extension band or just put it in a pocket of your cycling tights. When the pedal is in its lower position, the phone on your thigh will be located in its low point of "rest". When the same pedal reaches the highest point, your legs make half the rotation in the crankshaft. The phone's accelerometer detects low and high points of "rest" and calculates cadence in rotations per minute (rpm). This technology eliminates the need to wire a cadence sensor on your bike. Keep your bike slim and clean!

All your trip data is stored on the phone in CSV files and can be uploaded to a spreadsheet for training analysis or Google Earth for tracking.

VeloComputer application works on phones with accelerometer supporting JSR-256 (mobile sensor) and JSR-179 (LBS/GPS). You can also use it on GPS phones without an accelerometer (no cadence feature). In this case just put the phone in a pocket or mount it on the handlebar.

VeloComputer uses VeloTones for audible speed, acceleration and cadence monitoring. VeloTones, like ringtones, are digital sounds which allow cyclists to monitor speed, acceleration and cadence audibly, by listening to VeloTones without looking at the display. It's like having your personal coach riding with you and telling when to speed up, slow down, up-or-down shift to maintain your cadence. You can record your own VeloTones and configure them to fit your training needs. Keep your eyes on the road, not your display!

For higher accuracy measuring spot speed and acceleration we developed the VeloComputer bluetooth sensor. The sensor attaches to a quick release on a wheel of your bicycle and wirelessly transmits precise motion data to the VeloComputer application on your phone. The application instantly calculates and displays spot speed, acceleration, time and distance traveled.

Unlike traditional cycling computer sensors, which measure a full 360° (degree) wheel rotation, VeloComputer's innovative technology is capable of detecting as little as 1° (degree) of wheel rotation. This unique sensing technology is at least 360 times more accurate than traditional sensors. It measures accurate spot speed and acceleration in less than 1 second comparing up to 7 seconds delay in traditional cycling computers. The next version of VeloComputer will also measure the torque and power without any additional sensors on your bicycle.
