Is there a smartband like the Fitbit Air (no screen, just sensors) that doesn't bound me to Satan, and that doesn't cost a whopping 100€ to just know ho many steos I'm doing and the rithm of my heart?
I don't use smartwatches in favor of my beloved Casio, but I want a fairly cheap tracker that counts my steps, my heart beats, and similar things related to fitness and workouts. I won't buy a Mi Band or similar smart watches because as far as I know they suck in sensor accuracy, and a screenless device could last way more. I don't know if the gps would be beneficial or just a way to make a band more expensive, the possibility to track the jogging routes is fascinating, but maybe it's not that useful (I'm still at my first months of workout and light running).
A plus would be to have the possibility to link it to an open source app, just to be sure.
Is there a product alike with a better price? I don't care if it's not stylish, it has to be functional. Thanks in advance!
