## What is Axon?

Axon is your personal health coach — on-device app that reads Apple Health data and gives you four daily scores to understand your body.

SLEEP SCORE
Know if last night's sleep actually restored you. Axon analyses duration, efficiency, deep sleep, and consistency to give you a single number that tells you how recovered you really are.

RECOVERY SCORE
HRV and resting heart rate from your Apple Watch tell the story of how well your body bounced back overnight. A high recovery means you're ready to push. A low one means ease off.

STRAIN SCORE
Track how hard today's workout actually hit your body — not just calories, but intensity, heart rate zones, and duration combined into one number.

READINESS SCORE
Your daily bio-recharge level. Combines yesterday's sleep, today's recovery, and workout load into a single "go hard or go easy" signal every morning.

FOOD & NUTRITION
Log meals in seconds — breakfast, lunch, dinner, snacks — and see calories, protein, carbs, fat, and fibre against a daily goal that's estimated for you. Fuel and recovery, finally in one place.

WHAT MAKES AXON DIFFERENT
• 100% on-device — your health data never leaves your phone
• Evidence-based scoring using the same principles as premium health trackers
• Daily check-ins for mood, energy, and stress
• Guided meditation timer built in
• Practical tips for improving each score

Built for people who want to actually understand their body. Your four daily scores are available — no separate device to buy.

Your data. Your scores. No middleman.


## Version history (last 5 releases)

### 1.9.2 — 2026-09-01

Axon closes the loop: a heads-up before your usual bedtime, your week delivered every Monday morning, one fresh insight on Home each day — and new members see 120 days of their history from minute one. Plus: score cards that show how full each score really is, a Fit Age written by a heartbeat, and one refined typeface throughout.

### 1.9.1 — 2026-08-22

Axon now works the moment you open it — no sign-in needed. Set up in seconds, see today's scores right away. Sign in with Apple is still there in Profile whenever you want an invite code.

Fit Age, rebuilt:
• A cleaner page that tells you at a glance whether your cardio fitness is above or below typical for your age
• Your number now updates the same week you take new outdoor walks with your Watch
• If your last reading is older, Axon still shows your number — with an honest note about when it was measured

Also in this update:
• A new launch animation — the heartbeat draws our logo
• Opening Axon after midnight now shows a calm start to the day instead of a "no data" error
• Sign-in is more reliable, with clear guidance if Apple's sign-in can't complete
• Choose Light or Dark for Axon in Profile → Your details
• Many small fixes and polish throughout

### 1.9 — 2026-08-10

The biggest Axon update yet. A new Fit Age tab turns your cardio fitness into an age you can share. Choose light or dark — Axon now follows your style. Widgets got a full redesign, and scores are fairer to long sleepers and deep dreamers. Plus: a beautiful new launch screen, smoother charts, and dozens of refinements.

### 1.8.1 — 2026-08-08

Axon is on your wrist.

The new Apple Watch app shows today's Readiness, Sleep, Recovery and Strain at a glance, and complications put the score you care about right on your watch face. Your iPhone still does all the computing — the watch shows the answer, with the time it was measured.

Steps are sharper too: they roll over cleanly at midnight, refresh the moment you open the app, and now carry an "as of" time so you always know how current the number is.

And inviting a friend now opens your usual share sheet, so you can send it however you already message people.

### 1.8 — 2026-08-02

Your scores, at a glance — add Axon to your Lock Screen and Home Screen, and choose which score to show. Logging feels better too: the ring answers the moment food lands, and your daily check-in became the nicest ten seconds in the app
