The 935 is a wearable with a twist. It captures heart rate (HR) on your wrist and also pairs with a peanut-size pod that clips to the back of your shorts. The pod captures cadence, ground contact, stride length, vertical oscillation, left/right leg balance—which the 935 shows on your wrist, so you can check your form at any time midrun (no phone required).
Bonus: Automated interval timing for HIIT work, and suggested recovery before your next effort.
Could be better: Lets you forward texts/social media but not reply.
