⚡ How It Works
Step 1
Log in about 2 minutes
Mood, energy, sleep, symptoms, and whatever else stood out today — quick sliders and taps, not a form.
Step 2
HealthKit fills in what it can
Sleep, wrist temperature, workouts, and more prefill automatically — always optional, never overwriting what you typed.
Step 3
Patterns surface on their own
An on-device engine compares your days and flags real correlations — rated by strength (emerging, moderate, or strong) and explainable.
Step 4
Bring it to your next appointment
Export a doctor-ready PDF (Pro) or a free spreadsheet — for any date range, or everything since your last appointment.

⭐ Cadence Pro
Free covers day-to-day tracking. Pro unlocks the deeper analysis once you've got enough history to make it meaningful.
Pattern Insights
Correlation detection across sleep, mood, stress, and symptoms — rated by strength (emerging, moderate, or strong), always explainable.
PDF Export
A doctor-ready report with trends, averages, symptoms, medications and flares — clinical sections first, personal notes only if you include them. Previewed before you share.
90-Day Trends
Full trend history across every metric you track, not just 30 days.
Pattern Alerts
A notification when a new pattern shows up in your logs, plus a history of every one.
One-time purchase or monthly subscription — current pricing is shown in the app before you buy. Manage or cancel anytime via Settings → Apple ID → Subscriptions.
🔒 Privacy & Security
- No servers, period — Cadence has no backend of any kind. Purchases are verified on-device by Apple's StoreKit; there's no server to send a receipt to.
- HealthKit stays optional — and local — no feature is ever gated on Health access, nothing you type is overwritten, and values read from Health stay on your iPhone, never synced to iCloud.
- No account, no ads, no analytics — there's nothing to sign up for and nothing tracking you.
- On-device pattern engine — insights are deterministic correlation detection that runs entirely on your phone. No ML, no cloud processing, no black box.
- Your data, your iCloud — sync goes through your own private iCloud account. We never see it.
