Apple Health vs Mori
The short answer: Apple Health's Cycle Tracking is free, private and already on your iPhone — but it's iOS-only, tied to your Apple ID, and deliberately minimal (no confidence ranges, no export, no insights). Mori brings the same privacy-first model to Android with a purpose-built experience: date-range estimates with confidence, full export, and no account of any kind.
Side by side
| Apple Health (Cycle Tracking) | Mori | |
|---|---|---|
| Price | Free — built into iOS | All core features free forever; optional encrypted sync US$3.99 once |
| Account | Requires an Apple ID / iCloud account (implicit with iOS) | None. An email is only needed if you opt into cloud sync |
| Platforms | iPhone, iPad, Apple Watch only — no Android, no web | Android today (signed APK); iOS in progress |
| Where records live | On-device; iCloud sync optional — end-to-end encrypted with 2FA | On-device by default; optional sync uploads a client-encrypted snapshot |
| Prediction detail | Predicted period dates; notifications for period/fertile window | Date ranges with an explicit basis and confidence level, plus cycle phases and insights |
| Export / delete | Bulk Health export exists but is all-or-nothing across data types | Purpose-built export (JSON / CSV / readable summary) and one-tap delete-all of cycle data |
| Scope | One component inside a general health record hub | A focused period-tracking app — calendar, cycle ring, reminders, privacy center |
| Health-safety framing | Shows single predicted dates | Estimates labelled with confidence; explicitly not a diagnostic or contraceptive tool |
Where they genuinely differ
Ecosystem lock-in
Apple Health is excellent — if you stay inside Apple's ecosystem. It presumes an iPhone, an Apple ID and (for sync/backup) iCloud. Mori asks for none of that: no account of any kind, and your data isn't anchored to a platform identity.
Depth of the cycle experience
Cycle Tracking is a competent but minimal component inside a general-purpose health record. Mori is a dedicated tracker: interactive calendar marking, a cycle ring, four-phase breakdown, insight cards, discreet reminders, storage diagnostics and structured export — all designed around one job.
Transparency of estimates
Apple Health shows predicted dates without much explanation. Mori shows the estimate as a range, states what it was computed from, and lowers the confidence label when your history is irregular — so you always know how much to trust a number.
Which should you choose?
- Stay with Apple Health if you're on iPhone, want zero installs, and basic date predictions are enough. It's free, private and deeply integrated.
- Choose Mori if you're on Android, want a dedicated tracker with exportable data and confidence-labelled estimates — or simply don't want cycle data tied to a platform account. iOS version is in progress.
FAQ
Is Apple Health Cycle Tracking free?
Yes, it's built into iOS at no cost — but only inside the Apple ecosystem. Mori is also free (core features), runs on Android today, and never asks for any account — not even an Apple ID.
Which keeps period data more private, Apple Health or Mori?
Both are strong. Apple encrypts Health data on-device, and iCloud Health data is end-to-end encrypted when you have two-factor authentication. Mori stores records on-device by default with no account at all — there is no Apple ID or cloud account attached to your data in the first place.
Can I use Apple Health Cycle Tracking on Android?
No — Cycle Tracking is only available inside the Apple Health app on iPhone and Apple Watch. Mori exists for Android users who want the same privacy-first approach on their phone.
