Description
Welldo is a science-based Apple Watch app that monitors real-time stress, HRV, resting heart rate, sleep, and energy to improve overall well-being.
Welldo Stress Tracker helps you understand those signals and turn them into calmer, smarter daily habits. By translating complex health data into clear, human-friendly insights, Welldo shows you when to slow down, recharge, or keep going — without overwhelm.
STRESS TRACKING
Welldo analyzes your Heart Rate Variability (HRV) and Resting Heart Rate from Apple Health to continuously estimate your stress and recovery levels.
Instead of raw numbers or confusing charts, you get:
* Clear stress levels
* Easy-to-read trends
* Meaningful insights you can act on
Whether you’re working late, recovering from poor sleep, feeling mentally drained, or pushing your limits, Welldo helps you recognize stress early — before it turns into burnout.
REAL-TIME STRESS MONITORING — BACKED BY SCIENCE
Your body responds to stress instantly. Welldo tracks those physiological changes throughout the day to give you a real-time view of how your body is coping.
You’ll learn:
* When stress is building
* When your body is recovering
* How daily habits affect your balance
No data overload. Just calm awareness.
UNDERSTAND WHAT TRIGGERS YOUR STRESS
Welldo doesn’t just show how stressed you are — it helps you understand why.
By combining HRV, heart rate, sleep, and activity data, you can:
* Identify stress patterns
* Discover what impacts your recovery most
* Make better decisions for long-term wellbeing
Over time, your data starts telling a clear story — about you.
BODY BATTERY — KNOW HOW MUCH ENERGY YOU HAVE
Welldo’s Body Battery estimates how charged or depleted your body is using stress, recovery, sleep, and activity data.
Your Body Battery helps you understand:
* When your energy is charging
* When it’s draining
* How sleep, stress, and activity affect you over time
Track your energy trends daily, weekly, and monthly — and see how small changes lead to better balance.
BUILT FOR APPLE WATCH
Welldo is designed around an Apple Watch–first experience:
* Monitor stress and Body Battery directly from your wrist
* Use widgets and watch faces for quick, glanceable insights
* Stay aware without constantly checking your phone
Your wellness companion is always with you.
FEATURES
* Real-time HRV-based stress tracking
* Body Battery energy score
* Sleep, activity & recovery insights
* Activity Tracking
* Apple Watch widgets & watch face support
