Your mood is more predictable than you think.
MoodQuad is a daily mood tracker that reads your biometric data from Apple Health - heart rate variability (HRV), resting heart rate, respiratory rate, sleep, and workouts - and builds a personalized emotional forecast based on your patterns.
One tap per day. That's your only job. MoodQuad does the rest.
THE MOOD FORECAST
After 2 weeks of daily check-ins, MoodQuad predicts how you'll feel tomorrow based on how your body actually performed overnight. Not a generic wellness score. Your data. Your patterns. Your forecast.
Works with Apple Watch and Whoop via Apple Health. Choose your preferred data source in Settings.
HOW IT WORKS
Log your mood in one tap using the Circumplex Model - a scientifically validated framework that maps emotion across two axes instead of a single good-to-bad scale
MoodQuad reads your overnight HRV, resting heart rate, respiratory rate, and sleep from Apple Health automatically
Your Mood Map reveals patterns - what consistently lifts you up and what drags you down
The Prediction Ghost Dot shows where your mood is heading before it arrives
Tag activities to build a mood timeline connecting how you feel to what you were doing

Compatible with Apple Watch and Whoop. MoodQuad never writes to Apple Health and never transmits your data off your device. Everything stays on your iPhone. Always.
