Wow that's nice ! I especially like that you clearly explain the tradeoffs. One surprised me though: > No pressure sensor. There’s no barometric altimeter, so climbing is derived from elevation baked into the map tiles rather than measured — total ascent is an estimate. The gps from the device do not provide the altitude or is it not precise enough ?
