It has a great free tier and the paid version is pretty cheap too! It’s fantastic! It pairs with all my sensors (Moofit HW401 heart rate sensor, Magene S3+ speed/cadence sensors, Amazfit GTR2e smartwatch for heart rate with HR sharing configured) and it’s beautiful, shows all the info I need! I’ve tried about 10 biking apps and Cadence is the absolute best by far!
