Looking for a Period Diary alternative?
Period Diary is a long-running cycle calendar built around a diary metaphor, with day notes sitting next to your dates. MoodSwings is a different shape of app — and this page is an honest comparison rather than a pitch, so the table starts with what Period Diary does better.
Period Diary vs MoodSwings, side by side
| Period Diary | MoodSwings | |
|---|---|---|
| Known for | Period Diary is a long-running cycle calendar built around a diary metaphor, with day notes sitting next to your dates. | A calm period tracker built around how you actually feel: next-period and cycle-phase estimates, mood and symptom logging in a few taps, PMS patterns over time, and optional partner sharing. |
| Genuinely better at | Free-form journaling — if you want to write about a day rather than tap a symptom chip, it gives you the room. | MoodSwings turns the same days into structured mood and symptom data, so it can show you a pattern instead of a stack of entries to re-read. |
| Day to day it feels like | A full period-tracking app: calendar, logging, predictions and reading material, with cycle tracking as the main event. | One screen, a few taps a day. Dates, mood and symptoms in the same place — and if you want, a partner view where you choose what is visible. |
Stay with Period Diary if…
…writing it out longhand is the part you actually value.
We would rather you kept an app that fits than switched and stopped logging after a fortnight. A half-used tracker cannot show you a pattern.
What you get if you do switch
- Predictions that learn your pattern. Next-period, cycle-day and cycle-phase estimates that adjust as you log, instead of assuming a textbook 28 days.
- Mood and symptoms next to your dates. Cramps, bloating, sleep, energy, cravings and how you felt — logged in a few taps, kept as history.
- Your PMS pattern, over months. The days before your period stop being a surprise once you can see them repeating.
- Ovulation and fertile-window estimates when you want them, from your own logged cycles.
- Optional partner sharing, on your terms. You choose whether to share at all and what a partner can see — it is off until you turn it on.
