We built a leg-fidget counter. Here's what that actually took.

The problem nobody is measuring

Non-Exercise Activity Thermogenesis — NEAT — is the energy your body burns doing everything that isn't deliberate exercise. Fidgeting is a big part of it. Levine's research puts the gap between high and low fidgeters at 350 kcal/day. That's a real difference.

The problem: nobody knows how much they actually fidget. There's no baseline. We decided to build one.

What BinBot does

BinBot runs in the background on iPhone and Apple Watch and counts your leg movements across the day — three modes: shakes, jumps, rotations. It writes everything to HealthKit so the count lives in your health timeline alongside steps and sleep. A Live Activity and home screen widget keep the running total visible without opening the app.
