Burnout Zero
Read full descriptionHide full description
Burnout rarely arrives all at once. It builds over weeks of slightly-too-full days, until the tiredness stops lifting at the weekend. Burnout Zero helps you notice that drift early, while small changes still work. HOW IT WORKS Check in twice a day. In the morning, rate your energy, mood and how you slept. In the evening, rate how the day went and how well you recovered. It takes about twenty seconds. From those check-ins, Burnout Zero calculates a burnout score from 0 to 100 and tracks how it moves. You see which direction you are heading, not just how today felt. The score also explains itself, showing which factors moved it. WHAT YOU GET • A daily burnout score with a plain-language reading of what it means • Your recent trend, so a bad Tuesday does not look like a crisis • Boosters and drainers: log what lifts your energy and what flattens it, and see which ones actually matter for you • Personalised insights that name the pattern in your own data, with one concrete thing to try • Recovery suggestions sized for a working week, not a retreat • A daily goal to focus on, and an evening reflection to close the day • Optional reminders at times you choose APPLE HEALTH Connect Apple Health and Burnout Zero can read your sleep, steps, exercise and heart rate variability to sharpen the picture. This is entirely optional. The app works fully without it, and you can turn it off at any time. Health data is read-only, used only to calculate your score and personalise your insights, and never used for advertising or sold. PRIVACY Your check-ins are yours. If your employer provides Burnout Zero, they see only aggregate, anonymised team-level trends, never your individual scores, your reflections, or your health data. You can export everything you have logged, and delete your account and all its data from inside the app at any time. A NOTE ON WHAT THIS IS Burnout Zero is a wellbeing tool, not a medical device. It does not diagnose, treat or provide medical advice. If you are struggling, please talk to a doctor or a qualified professional.
