You can even backup your ride data and re-import it on new devices. Get announcements while you ride for how long or how far you have gone. When you finish a ride, sync it to Apple Health! - WORKS WITH POPULAR SENSOR Wahoo, Moofit, Garmin, Magene, you name it, My Cadence is ready for your cadence sensor. It even works with certain fitness bikes like the Schwinn IC4! Sensors that broadcast the "Speed & Cadence" profile are compatible. You may not see a reading on Cycle Power crank arms or bikes that have built in custom sensors. We are continuously adding support for new sensors.

Verdict
The clearest difference is in-app purchases: 1SecondLap at none against My Cadence's 2. 1SecondLap also leads on update cadence (daily vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
