This app collects many of main mathematical formulas, from the simple and used ones. In fact, it offers a fast tool to convert pace to speed and viceversa. It offers also a simpe Riegel calculation, which is an empirical formula, which estimates the performace on a distance given a performance on a smaller distance. It includes a tool to estimate the athletic track laps based on the average pace. The last page contains two sections: the former is to calculate the average speed and average pace given the distance and the time of a performace, the latter calculates a performace in percentage to another time (for example, respect to the winner). All formulas support both International System Units (km) and Imperial System Units (miles).
The PRO version enables you to use the performance percentage calculation, enables to predict a performance based on preferred baseline, and enables ads-free experience.
