Looking for a Polar alternative?
Polar builds training-focused watches, and Polar Flow includes menstrual cycle tracking aimed at athletes planning sessions around their cycle. MoodSwings is a different shape of app — and this page is an honest comparison rather than a pitch, so the table starts with what Polar does better.
Polar vs MoodSwings, side by side
| Polar | MoodSwings | |
|---|---|---|
| Known for | Polar builds training-focused watches, and Polar Flow includes menstrual cycle tracking aimed at athletes planning sessions around their cycle. | 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 | Training science — cycle data sits next to genuinely serious load, recovery and workout analysis. | MoodSwings makes no training recommendations at all; it keeps the cycle-and-mood record that a training platform treats as a side note. |
| Day to day it feels like | Cycle tracking is one module inside a much bigger sleep, activity and recovery platform you wear. | 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 Polar if…
…you train by the numbers and your watch is already the hub.
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.
