Which hours of your week actually paid for themselves? brainful puts a b-score on every meeting, session, call and quiet hour — 0 to 100, how much that experience genuinely engaged you — read live from the strap you already wear. Plus a curve, so you can see when an hour peaked and when it faded. You don't log anything. No journal, no rating, no remembering. It reads the strap and puts the number on the meeting. If you run a company, work a floor, or train seriously, your body is activated most of the day. That isn't a warning, it's the job — and it's why a stress number that reads high whether the day was brilliant or wasted can't help you. That number is measuring your constant. brainful measures the return. WHAT YOU GET * A b-score for every calendar event, scored live as your day happens * The shape of each hour: when it peaked, when it faded, what it held * A short written read on each event, computed from your own data — never generic, never invented * Notes for the moments no calendar sees: the hard phone call, the walk that fixed everything * A daily timeline that shows your day the way it actually landed * Share cards for the scores worth talking about PRIVATE BY ARCHITECTURE Your heart rate is never stored — it's scored in the moment and discarded. Your scores never leave your phone. No location tracking, no HealthKit, no account holding your data on a server. brainful reads your calendar to label your day; it keeps nothing else. WHAT YOU NEED A Whoop strap (4.0 or later), Amazfit Helio, or Fitbit Air, an iPhone, and a calendar. That's it — brainful works alongside the strap app, not instead of it. brainful starts scoring from your first day. The subscription comes later, once you've seen what your days actually look like.
