Serious lifters know that accurate tracking is the difference between stagnation and progress, but the act of logging has always been in the way. Pulling out your phone between sets, manually entering weights, trying to remember what you loaded two weeks ago, it all breaks focus and fragments the experience of training. Hound was built to eliminate all friction with tracking ones workouts, in the same way you get on the treadmill without thinking about wether or not it will accurately capture your data. Using patent-pending NFC tags that attach to weight plates and a sensor with a large display that snaps to the barbell, the system automatically identifies the load being lifted and logs every set in real time. Hound tracks reps, sets, weight, and velocity. The design challenge was making a hardware-software ecosystem that felt truly invisible. A product whose best feature is that you never have to think about it. We obsessed over the physical interaction model (zero buttons during a lift), the information architecture of the app (actionable metrics over raw data), and the onboarding flow so the system felt intuitive from the first session, especially for first users. Hound was built by myself and a co founder who handled the firmware engineering.
