## What is Energy Gauge?

Know how hard you can work today - before your first meeting.

Capacity Gauge reads your sleep, HRV, and calendar to give you one clear daily readiness score. Not a vague wellness number. A signal built for knowledge workers who need to make smart decisions about where to put their energy.

How it works
Every morning, Capacity Gauge pulls data from Apple Health and your calendar - entirely on-device - and computes a single 0-100 readiness score. You see your status at a glance (Good, Fair, Low, Critical) with a plain-English explanation and 1-3 actionable suggestions tailored to your specific day.

No cloud processing. No account required. No data ever leaves your iPhone.

What it measures:
- Sleep duration and consistency from the last night
- Heart rate variability (HRV) trends vs. your personal 14-day baseline
- Calendar load: total meeting hours, context switches, and back-to-back blocks
- Early wake, fragmented sleep, and short-sleep anomalies

What makes it different:
- Most readiness apps compare you to population averages. Capacity Gauge compares you to you. Anomalies are flagged relative to your own rolling baseline - so a 6-hour night might be fine for you, or a warning sign, depending on your pattern.
- The calendar integration goes beyond step counts. Heavy meeting days reduce your score before you've started — so you can protect a deep-work block before it gets swallowed by reactive work.
- AI Insights powered by Apple Intelligence

Works with your wearable
Reads HRV and sleep from Apple Watch, Oura Ring, Ultrahuman, Whoop, Garmin, and any other device that syncs to Apple Health.

Adapts to your role
Tell Capacity Gauge whether your work is deep-focus, mixed, or mostly collaboration — and the scoring logic adjusts to what actually drains your kind of work.

Privacy by design
Sleep data, HRV, calendar events, and your readiness score never leave your device. No server. No account. No subscription required for core features. Everything is processed locally using Apple Health and EventKit.

Perfect for
Founders, developers, writers, designers, researchers — anyone whose best output depends on showing up with the right mental energy at the right time.

Stop guessing. Start each day knowing.
