Health scores that actually make sense

Axon reads your Apple Health data and gives you four daily scores — Sleep, Recovery, Strain, and Readiness — so you know exactly how your body is doing.

Your Four Scores

Sleep

Duration, efficiency, and stage quality from last night.

Recovery

HRV and resting heart rate to gauge how well you bounced back.

Strain

Workout load and intensity from today's activity.

Readiness

Your overall bio-recharge — ready to push hard or rest?

Frequently Asked Questions

Does Axon require an Apple Watch?

No. Axon works with iPhone data only (steps, workouts, sleep from the iPhone accelerometer). However, an Apple Watch significantly improves accuracy — it unlocks sleep stages, HRV, resting heart rate, and full workout metrics. Without it, missing metrics score a neutral 50 rather than 0.

Why is my score 0 or blank?

Scores calculate from your Apple Health data. On your first day or after granting HealthKit access, Axon needs at least one night of sleep data and some activity data to generate meaningful scores. Open the Health app to confirm data is being recorded.

How do I grant HealthKit permissions?

During onboarding, tap "Continue" on the HealthKit page and approve all categories. To adjust later: iOS Settings → Privacy & Security → Health → Axon.

Is my health data sent to any servers?

Axon is local-first. Raw HealthKit data never leaves your device. Optional anonymous sync sends only aggregated daily score summaries (not raw health data) to Supabase to back up your history. You can review the full Privacy Policy.

How do I cancel my subscription?

Subscriptions are managed by Apple. Go to iOS Settings → [Your Name] → Subscriptions → Axon → Cancel Subscription. You keep access until the end of the current billing period.

How do I delete my account and data?

Inside the app: Profile → scroll to the bottom → tap "Delete Account". This permanently removes all your scores, check-ins, journal entries, and account data from both the device and our servers. This action cannot be undone.

The app says my HealthKit data is unavailable — what do I do?

This usually means permissions were denied or the Health app has no data for a metric. Check iOS Settings → Privacy & Security → Health → Axon and ensure all categories are toggled on. Then open Axon and pull to refresh on the Body tab.

What iOS version does Axon require?

iOS 17.0 or later. Axon is optimised for iPhone and requires iOS 17 for its scoring engine.
