Welldo reads the health data your Apple Watch already collects and turns it into clear, daily stress insights.
No manual logging, no extra hardware.
Features
Real-time stress, Body Battery, Sleep Score, and many more features, all working together on your wrist.
Real-Time Stress
Know where you stand, right now. Welldo reads your heart rate and HRV and turns them into a stress level you can actually understand: Great, Normal, Pay Attention, Overload. No guessing, no waiting.
The other half of the story. Your Sleep Score, your stages (REM, Core, Deep), broken down so you can see exactly why yesterday's stress looked the way it did.
Sleep Tracking
HRV Tracking
The signal behind the score. Welldo reads your heart rate variability continuously and compares it to your own baseline, so a stress reading isn't a guess. It's your body, measured against itself.
Body Battery
The context behind your stress score. One number tells you how much energy you've got left. Watch it drain through a hard day, watch it climb back with rest.
Built on Privacy
Your data stays on your iPhone. Everything runs through Apple Health, no servers, no accounts, no one else sees it.
Insights That Matter
Your trends are compared to your own history, so every insight is personal, meaningful, and easy to understand.
Progress You Can See
Follow your health across days, weeks, months, and years, and watch how small changes lead to lasting improvements.

Understand Every Stress Level
