MAJELLA: PRIVATE PERIOD TRACKING AND CYCLE CHARTING
Product overview updated 5 October 2026

Majella brings private period tracking and personal cycle charting to iPhone and Android. Built for women practising natural family planning, it keeps everyday records in a calm, dignified space and supports learning with an instructor.

Your own observations, together
Record periods, basal body temperature, wrist or skin temperature from supported health sources, cervical mucus observations and LH test results alongside symptoms, moods and notes. Temperature sources stay separate so you and your instructor can see what was recorded. Personal codes and colours help the chart match your own shorthand.

Period estimates, without fertility verdicts
Majella estimates when the next period may arrive from cycle dates alone. It does not interpret temperature, mucus or test results, predict fertility, or identify fertile and infertile days. Reading your chart for natural family planning remains your work with your instructor. The cycle wheel and hormone illustration are teaching pictures of a typical cycle, not measurements of your body.

A record you can take with you
Calendar and Insights gather cycle and period history, symptoms and moods. Pro charting adds temperature views and comparisons, personal chart codes and chart PDF sharing. CSV and JSON import and export make records portable. Free period tracking and monthly or yearly Pro subscriptions are offered; current prices and eligibility appear in the app.

Private by design
Cycle records are stored locally, with optional sync or backup through your own iCloud account on iPhone or Google Drive account on Android. Optional Apple Health and Health Connect connections use the permissions you grant and require supported devices and readings. No Majella account is required for local use. RevenueCat handles subscriptions.

For learning and charting
Majella is a charting tool, not a contraceptive method or medical device, and does not provide medical advice. It supports your records and education; it does not replace method instruction or your physician.
