Everything Mahina does
Here's the whole toolkit: tracking, predictions, the pregnancy side, and the privacy bits. All of it runs on your phone, with or without a signal.
Honest predictions
Mahina never shows a single bold date it can't stand behind. When your cycles vary, you get a clear range with a confidence label — high, medium, low, or irregular. Logging more cycles sharpens it over time. This honesty is the app's signature.
Period & symptom logging
Log a period in about ten seconds — from the calendar, a one-tap home-screen widget, or a notification action. Track 60+ symptoms: flow, pain, mood, energy, sleep, skin, discharge, cravings, and your own custom tags.
Fertile-window estimate
See an estimated fertile window, always clearly labelled an estimate — not for contraception. Mahina is a tracker, not a birth-control method.
Cycle history & stats
Your average, shortest and longest cycle and period lengths, plus a variability read — computed on your phone from what you log.
Pregnancy mode
Enter your last period or a known due date and follow your pregnancy week by week, with doctor-reviewed development notes, trimester milestones, and appointment & supplement reminders. Switching modes never deletes your cycle history.
A compassionate off-ramp
If a pregnancy ends, a gentle, judgement-free path is always within reach. It puts pregnancy content away immediately and stays ad-free — for as long as you need.
Insights that make sense
A "Today" card shows your current phase or pregnancy week, what's typical, and a gentle tip. Simple pattern notes ("headache in 4 of your last 5 luteal phases") are worked out on-device — no machine learning, no server.
Doctor PDF export
Generate a clean, clinical summary of your recent cycles or your pregnancy — created on your device and shared through your phone's own share sheet, only when you choose.
Share cards, on your terms
Presets for a doctor, partner, or parent — with an item-by-item preview so you send exactly what you mean to, and nothing more. No server is involved.
App lock
Lock Mahina behind a PIN or your device biometric, with an auto-lock delay you control.
Encrypted backup
Export an encrypted backup to a file, protected by a passphrase only you know. We keep no copy and cannot read it. Restore it whenever you like.
Neutral reminders
Custom reminders with your own wording and times. By default they stay neutral on your lock screen — no cycle or pregnancy details unless you turn that on.
Home-screen widgets
Glance at your cycle day, days-to-period, or pregnancy week without opening the app.
A small, honest library
Doctor-reviewed articles on periods, PCOS basics, first periods, myth-busting, and the pregnancy trimesters — bundled in the app, readable offline.
Dark mode & big text
A calm dark theme, full support for 200% system text size, and screen-reader-friendly labels throughout.
Works fully offline
Every feature above runs without a network. In this version, the app makes no internet connection at all.
Free, and staying that way
Everything is free, with no feature gating and no ads. Our public promise: nothing free is ever taken away.
