iSpinning , a Spinning computer that tracks and record cardio exercise; and

iNewLeaf , a cardio fitness system and cycling computer that lets users incorporate a New Leaf metabolic profile to more precisely track and monitor the right workout intensity.

All three apps are free downloads from the App Store. The SMHeart Link sells for US$155; for a limited time, it's bundled with SMHeart Sleeve, a lightweight case that integrates with the heart monitor chest strap.
