Activity Tracker Review & Comparison: Guide by Features
The Activity trackers below all have Windows and Mac compatible with no heart rate monitor and uses 3-axis accelerometer to measure your activity. Since most of them are meant to be worn on your wrist or belt, activity trackers are very accurate for walking and running activities, but less so for other sports. Here are the top fitness monitors. Please feel free to comment if you have any questions.
Key Speed and Distance Watch Features
GPS vs. Accelerometer
GPS (or global positioning system) receiver is used to locate satellites in orbit to deduce your position and speed, a mathematical principle called trilateration. This method is highly precise and does not require any type of calibration to your watch. One downside to GPS training watches is that it requires a clear line of vision to the sky. Did you ever notice your car GPS or your Sirius satellite radio zones out when you drive into the tunnel, bridge or in big cities?
The other method used to measure your speed and distance is an accelerometer watch. There is definitely some science to this, but to keep it simple, its a device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or they could be dynamic – caused by moving or vibrating the accelerometer. This technology can be found on your iPhones and Wii joysticks.
