Finally, something to show your doctor.
Sulu is a free perimenopause app. A 30-second daily check-in that tracks your symptoms, spots patterns, and exports a clear summary for your next appointment.
Built for how you actually feel
Not another generic health app. Sulu is designed specifically for the perimenopause experience, track, understand, and share.
Daily Check-In
Too much to remember
A 30-second check-in that captures what memory can't. Track your symptoms, lifestyle markers, and how they shift over time.
Insights & Patterns
It all feels random
Your timeline shows symptoms side by side, spot connections between sleep, mood, hot flashes, and more.
Doctor Export
Nothing concrete to show
Export a clear PDF summary to bring to your next appointment. Finally, something your doctor can work with.
Supplement & HRT Tracking
Is this even helping?
Log supplements and HRT alongside your symptoms. Track regimens, spot what's working, and feed it all into your doctor report.
How it works
A few minutes a day can change how you understand your body. Sulu helps you track, see patterns, and share with confidence.
