Description

Wake up, sync your Garmin and look at your watch and know what kind of day your body is ready for. KnowYourDay condenses everything your Garmin records, day and night, into one clear morning outlook, measured against your own personal baselines rather than population averages. Every morning you get: • A clear verdict: All good, Great night, Mostly fine, Take it easy or Recovery day • One practical tip for the day, for example "Good day to train" or "Get to bed early tonight" • What stands out: the one or two things that really changed overnight • Your numbers at a glance, each colour-coded against your usual range KnowYourDay reads: • Overnight HRV • Sleeping heart rate • Sleep duration • Overnight stress • Respiration • SpO2 • How strongly your heart reacts to effort Plus two trend views: My Body Data Your body signals over the last 1 or 2 weeks. My Sleep Data Your sleep pattern over the last 1 or 2 weeks. Why the night matters: Your night is the most honest measurement of the day. No workouts, no coffee, no meetings, just your body recovering. That's when stress, illness, overtraining or a short night show up first, often before you feel them. Wear your watch day and night, especially at night, and KnowYourDay turns those quiet hours into a reliable outlook for the day ahead. More than a single number: A single HRV or sleep score has limited meaning without context. KnowYourDay compares every night with your personal history: • Your usual range over the last 28 nights • The last few nights, to catch a trend early • Your strongest nights over the past months This makes it possible to look beyond: "What was my score?" and start asking: "Is this normal for me, and what should I do with today?" How it works: Install KnowYourDay and connect it once to DreamDoc (free). Wear your watch day and night and sync with Garmin Connect. After 3 nights you get your first report. After about a week your personal baselines are fully in place. Your data, over time Your nights build up into a long-term history instead of disappearing as isolated daily scores. On request you'll also receive the full report by email every morning. KnowYourDay is free to download and use on compatible Garmin devices. Wear it overnight. Wake up informed. Know your day. KnowYourDay is not a medical App and just for informational purpose. In case you have problems or find a bug, please do not rate this App with 1 star but contact us at [email protected] and we fix your issue.
