Looking for a Flow by Perigee alternative?
Flow by Perigee is a design-led iOS period tracker with a strong emphasis on privacy and a calm, native-feeling interface. MoodSwings is a different shape of app — and this page is an honest comparison rather than a pitch, so the table starts with what Flow by Perigee does better.
Flow by Perigee vs MoodSwings, side by side
| Flow by Perigee | MoodSwings | |
|---|---|---|
| Known for | Flow by Perigee is a design-led iOS period tracker with a strong emphasis on privacy and a calm, native-feeling interface. | 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 | Native iOS craft and a privacy-first stance — it is one of the nicest-looking trackers on the platform. | MoodSwings is just as quiet but built around mood: the PMS pattern is the headline, not an extra tab, and a partner can see only what you choose. |
| 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 Flow by Perigee if…
…the interface is what keeps you opening it and you track dates more than feelings.
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.
