Maren is a privacy-first period, mood & symptom tracker. Your health data stays on your device — we never see it, sell it, or lock it behind a paywall.
Free forever for tracking · Premium monthly/yearly subscriptions or a one-time lifetime purchase
Explore the calendar, perimenopause records, and daily mood and symptom logging.
No accounts, no servers holding your health data, no ads, no third-party trackers.
All health entries live only on your device — never in iCloud, never on any server. Even we can't access them.
We never sell, rent, or share your data, and embed no advertising or tracking SDKs. Period.
Use raw CSV/PDF export, a clinician report, or a password-encrypted manual backup. Local records remain fully deletable — never paywalled.
Maren learns your cycle instead of assuming "day 14" ovulation, so it works for 15–120 day cycles, PCOS, and everything in between.
Track flow, see the four cycle phases color-coded, with honest confidence ranges — not fake precision.
Statistical model that adapts to your history and shows a range, not a false "exact day".
Log mood, energy, pain, sleep, weight, basal body temperature, spotting, notes, and custom items.
On-device trends, recent-cycle comparison, and correlation exploration. Premium.
Period, PMS self-care, and phase-aware nudges. Medication multi-time & weekday scheduling. Premium.
Choose menstrual flow, body mass, sleep, basal temperature, spotting, step count, or Apple Exercise Time. Sleep, steps, and exercise time are read-only; no Health data is sent to a developer server.
Quick-log with App Shortcuts, an interactive widget, or the Apple Watch app and Smart Stack.
Generate a structured PDF for a healthcare visit. Maren warns you that shared CSV/PDF files are not encrypted.
Export a password-encrypted backup, preview it before import, and choose safe merge or confirmed replacement.
