Looking for a Bom Calendar alternative?
Bom Calendar is a simple, friendly period calendar focused on logging your dates and seeing the next one coming. MoodSwings is a different shape of app — and this page is an honest comparison rather than a pitch, so the table starts with what Bom Calendar does better.
Bom Calendar vs MoodSwings, side by side
| Bom Calendar | MoodSwings | |
|---|---|---|
| Known for | Bom Calendar is a simple, friendly period calendar focused on logging your dates and seeing the next one coming. | 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 | Being small and unfussy, with a look a lot of people find calmer than the big clinical trackers. | MoodSwings is similarly small but keeps mood and symptoms in the same few taps, and offers a partner view if you want one. |
| 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 Bom Calendar if…
…you only want the dates and would not use mood logging or partner sharing.
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.
