Chart your cycle your way. Designed to be private. No accounts, no ads, no trackers and your data stays on your phone.
Majella is a catholic charting app for natural family planning.
If you chart your cycle the way an instructor teaches it, temperature in the morning, mucus observations, LH strips, marking your own peak day, Majella gives all of that a proper home. You log what you observe each day and your chart builds itself, clean and easy to read.
We built Majella for our own family first, and it shows in the choices. No accounts. No ads. No trackers. Your data stays on your phone, and if you ever want it gone, one tap deletes everything.
There's a calendar view worked out from your dates, so you can see at a glance where you are in the month, and every cycle you've recorded is kept for you to look back on.
Majella can also sync with Apple Health, so temperatures and observations you've recorded elsewhere land on your chart without typing them twice. And if you work with an instructor, Premium lets you export your chart as a PDF to bring along.
Majella is a charting tool and period tracker. It's not a medical device, not a diagnosis and not a method of contraception. Decisions about avoiding or achieving pregnancy belong with you, a certified fertility awareness instructor and your doctor.

Ratings & Reviews
This update is about the chart itself.
- Your chart, calendar and daily log now show only what you have recorded and a clearly-labelled generic calendar view — never a fertility verdict.
- Apple Health syncing covers temperature, cervical mucus, menstrual flow, ovulation tests, intercourse and cycle symptoms, and the permission screen now names all of them.
- Clearer wording throughout, including the Apple Health permission screens.
- Stability and reliability improvements.
