Because I both run and love tech, I have sampled quite a few running apps -- at least a dozen. I can attest that none of them are entirely accurate in tracking indoor distances, but using the calibration options some of them offer really helps. Even so, if I really, truly, absolutely feel like I need to accurately gauge my pace, I take it outside.
