It's been several years since we did the MS150, but we had Wahoo Elemnt computers that tracked heart rate, rpm, speed, elevation. We didn't have power meters. Something (I can't remember if it was the computer or strava) estimated calories. They could be used stand alone, but I think they provided even more capabilities if you had a linked smart phone with you. If you didn't take your phone, the data would sync to your phone when you got back to your phone. At the time, the Wahoo Elemnt (can't remember which) got good reviews and, I think were competitive with the Garmin stuff.
