ARE YOU COOKED OR LOCKED IN?
Stop guessing why you feel like an NPC today. Capacity turns your health data into a single, brutal, and honest battery score (0-100%).
You charge your phone every night. Why don't you check your own battery?
Whether you are a gym rat chasing a PR, a corporate warrior surviving on caffeine, or just a bestie trying to avoid a breakdown—Capacity is your new daily operating system.
WHY CAPACITY?
Most health trackers are boring. They give you graphs you don’t understand. Capacity gives you the VIBE CHECK you actually need.
We analyze your sleep, Heart Rate Variability (HRV), and Resting Heart Rate to tell you exactly how much gas is left in the tank.
