Looking for a Modern Fertility alternative?
Modern Fertility pairs at-home hormone testing with an app that tracks cycles and explains the results. MoodSwings is a different shape of app — and this page is an honest comparison rather than a pitch, so the table starts with what Modern Fertility does better.
Modern Fertility vs MoodSwings, side by side
| Modern Fertility | MoodSwings | |
|---|---|---|
| Known for | Modern Fertility pairs at-home hormone testing with an app that tracks cycles and explains the results. | 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 | Lab-grade hormone panels with clear explanations — a genuine clinical data point about your own body. | MoodSwings is the everyday layer instead: your dates, your mood, your symptoms, with nothing to order and no results to wait for. |
| Day to day it feels like | The app is the readout for a device or test strips you buy — precise fertility data, but there is kit to keep using and replacing. | 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 Modern Fertility if…
…the testing is the point and the app is how you read it.
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.
MoodSwings is a wellness tracker, not a medical device, and makes no clinical claims — its dates are estimates from your own logged cycles.
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.
