Tempdrop vs MoodSwings, side by side

Tempdrop MoodSwings
Known for Tempdrop is a wearable armband that measures temperature overnight, made for people whose sleep is too irregular for a morning thermometer. 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 Real-world temperature data — it works through broken sleep, shift work and night feeds, which oral thermometers do not. MoodSwings does not measure anything; it learns from the cycles you log and puts your dates, mood and symptoms in one calm place.
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 Tempdrop if…

…temperature data matters to you and your sleep makes a morning reading unreliable.

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.
