With CronoBOX you can participate in virtual races with checkpoints to guarantee that all runners can do the same race and under the same conditions, avoiding choosing too favorable route profiles, thus harming those who decide to run on other profiles with more unevenness or more technical.
It is important to note that in order to properly record the route and obtain the approval of each control point, IT IS NECESSARY TO KEEP THE DEVICE DISPLAY ON ALWAYS, until the end of the tour. This is because it is not a native app, and it is impossible to execute the code in the background, so even if we receive the position coordinates, we cannot verify that we have passed the control points.
We also remember that it is a free app without advertising and the developer is not a computer professional, so bear in mind that there may be some unexpected bugs. In this case, they will be corrected as soon as possible.
