Looking for alternatives to carry smartphone during workouts we found SmartWatch wrist case offered by Wantalis.
Say goodbye to your armband and do your jogging with your smartphone under the eyes – is how the French manufacturer from Marseilles promotes the product. Indeed very handy and makes managing your phone far easier. Having tested with Sportovia app we did not observe any discrepancies of distance, pace or elevation gain vs high-end GPS watch or a smartphone fixed to the arm or placed in a belt. Works very well in winter but we have to wait a while to check it in warmer conditions.
