MAJELLA FACT SHEET
Product overview updated 5 October 2026

The essentials
Majella is a private period tracker and charting notebook for iPhone and Android, made for women who practise natural family planning. The body has a language. Majella helps you listen.

What it does
Record periods, temperatures, cervical mucus observations, LH test results, symptoms and moods. View your records together, compare cycles in Insights, use personal chart codes and colours, and share a chart PDF with your instructor. CSV and JSON import and export help you keep a portable record.

What it estimates
Majella estimates when your next period may arrive from your cycle dates. It does not interpret your temperature, mucus or test results, predict fertility, or tell you which days are fertile or infertile. The coloured cycle wheel and hormone illustration show a typical cycle for learning; they do not measure your hormones or read your charted signs.

Free and Pro
Free period tracking includes period records, calendar views and cycle-history insights. Majella Pro adds temperature and observation charting, temperature comparisons, personal chart codes and chart PDF sharing. Monthly and yearly subscriptions are offered. See the app for current prices, terms and eligibility.

Privacy and connections
Cycle records are stored locally. Optional cloud sync or backup uses your own iCloud account on iPhone or Google Drive account on Android. Optional Apple Health or Health Connect connections depend on permissions, device support and available readings. BBT and wrist or skin temperature are recorded as separate series. No Majella account is required for local use. RevenueCat handles subscriptions.

Platforms and contact
Minimum app requirements: iPhone with iOS 17 or later; Android 7.0 or later. Health integrations have additional device and feature requirements. Website and media enquiries: majellafertility.com/press. Developer: Trinitas Homes Pty Ltd, Melbourne, Australia.

Important
Majella is a charting tool, not a contraceptive method or medical device. It does not provide medical advice. Learn your method with a certified NFP instructor and speak with your physician about health concerns.
