Mood patterns, not mood faces
Make sense of your bipolar moods.
See your patterns. Catch shifts before they hit. Log a quick mood once a day, or again when the day changes — with optional clinical scales for depression, elevation, irritability, and anxiety. Sleep and meds in the same view, on iPhone, Apple Watch, and your Lock Screen.

How it works
Thirty seconds a day. A clearer visit at the end of the month.
No streak guilt, no notification spam, no "congratulations on day 7". Just a chart your clinician can read at a glance.

Tap to log how you feel
One-tap mood. Add clinical scales, sleep, and a meds toggle when you have a minute. Optional daily reminder.
Watch the pattern emerge
Sleep, meds, and mood plotted together — the connections you suspected, in one view.
Bring it to your appointment
A clear month of mood, sleep, and meds. Hand over a clinician PDF report (Pro), or export the raw CSV — free, always.
Why it's different
Generic mood diaries
A row of happy faces. Fine for general well-being; misses what bipolar moves on. No clinical scales, no episode patterns, no meds field.
MoodSync
Quick mood tap, plus optional clinical scales for depression, elevation, irritability, and anxiety. Sleep and meds in the same view. Built around the bipolar visit.
- Apple Watch app and complication for one-tap wrist logging
- Home and Lock Screen widgets that keep the streak visible
- Sleep hours autofilled from Apple Health
- A PDF report your psychiatrist can actually read
Your mood data is yours.
No MoodSync account. Mood entries stay on your device, with optional private iCloud sync.
A note from the maker
Why I built MoodSync
Most mood diaries assume your mood drifts gently. Mine doesn't — I live with bipolar disorder. Mood shifts your week, your sleep, your meds conversation, your next appointment.
The clinical-style scales, the sleep tracking, the meds toggle — they're what people actually bring to care, so that's what the app captures. The Watch app exists because the days I most needed to log were the days opening a phone app felt impossible.
Free to start, and the data is yours. If something is missing, the support link in the footer reaches the person who decides what gets built next.
