eMoods has been a steady bipolar tracker on the App Store for years. If you have used it, the scales will feel familiar. The comparison below is for choosing between two apps in the same lane, not for arguing one is universally better.

Where eMoods works well

eMoods was bipolar-focused from the start. It logs depressed and elevated mood, anxiety, and irritability separately. It produces a monthly PDF you can email yourself or your clinician. The Pro tier adds cloud sync and additional fields.

Where MoodSync goes further

Clinical depression rating has used compact ordinal anchors (mostly 0–4) since 19601960; mania has used a similar 0–4/0–8 anchor since 19781978. MoodSync uses a 0–3 self-rating in the same compact-ordinal tradition, which keeps values stable from week to week without re-anchoring.

Sleep hours sit on the same chart as mood by default. Sleep is one of the most consistent prodromes of a mood episode in bipolar disorder2008; in MoodSync the connection shows up without you having to look in two places.

The privacy posture differs too. MoodSync syncs through your own private iCloud, with no MoodSync account or server in the path.

When eMoods is still the right choice

If a printable monthly PDF is the thing you bring to your psychiatrist, eMoods has it built in and MoodSync does not. And if you want cross-device sync outside the Apple ecosystem, eMoods Pro is the path.

FAQ

Is eMoods designed for bipolar disorder?

Yes. eMoods is one of the longest-running bipolar-specific mood trackers on the App Store. It logs depressed and elevated mood, anxiety, and irritability separately, and it produces a printable monthly report.

What does MoodSync do that eMoods does not?

MoodSync uses 0–3 clinical-style anchors on each mood scale, plots sleep hours and a daily 'meds taken' yes/no on the same chart as mood, and stores your data on your device with optional private iCloud sync. eMoods uses a slider-style scale and offers an in-app PDF email report.
