Questions
Do I need an Apple Watch?
DayGlint is at its best with one. Recovery, sleep stages, heart rate variability and strain come from the readings your Watch saves to Apple Health.
With only an iPhone, DayGlint shows what Apple Health has, such as steps, walking metrics and data that other apps and devices save there.
Which apps work with DayGlint?
Any app that saves to Apple Health: Apple Workout, Strava, Nike Run Club, Garmin Connect, Oura, WHOOP, AutoSleep and many more. Allow the app to write to Apple Health in its own settings, and DayGlint reads what it saves.
Strava sometimes saves workouts without heart rate. DayGlint then estimates their strain from duration and effort, and marks them as estimated. A workout that arrives from two apps, such as your Watch and Strava, is counted once.
Why does it say “Learning”?
Scores compare each day with your own usual range, so DayGlint needs some of your history first. Baselines take about two weeks; until then you will see “Learning, day 6 of 14” and the scores sharpen as the days add up.
How do I get more HRV readings at night?
Apple Watch takes only a few heart rate variability readings a night, so single nights can be noisy. Wear your Watch to sleep with a sleep schedule set up in the Health app, or turn on the Sleep Focus. The Watch then takes more readings, and recovery gets steadier.
Some of my numbers are missing
Check what DayGlint is allowed to read: Settings › Apps › Health › Data Access & Devices › DayGlint, and turn on the types you want. On some versions of iOS the path starts Settings › Health.
Apple does not tell apps when a permission is declined, so a declined type simply looks like missing data. Also check that the app or device that measures it saves to Apple Health.
Is my data uploaded?
No. DayGlint has no servers and no account. Your health data stays on your iPhone and Apple Watch, and the Watch gets its summaries straight from your iPhone. The only thing DayGlint keeps in iCloud is your tile layout, which holds no health data. The privacy policy has the details.
Is DayGlint medical advice?
No. DayGlint shows patterns in your own data to help you plan your day. It does not diagnose, treat or prevent any condition. If something about your health worries you, talk to a doctor.
How do I delete my data?
In DayGlint, open You › Data and privacy › Delete all data. That removes everything DayGlint keeps on your iPhone and Apple Watch. Your data in Apple Health stays as it is. Deleting the app also removes what it keeps on the device.
To keep a copy first, use Export data on the same screen.
What is estimated sleep?
An option you turn on for nights your Watch has no sleep, for example when it was on the charger. DayGlint estimates the night from your iPhone’s motion, on the device. Estimated nights are always labelled as estimated, are kept only as a short summary for a few days, and are never written to Apple Health.
Does DayGlint record workouts?
DayGlint reads workouts rather than recording them, so keep using Apple Workout or the app you like. To add something those apps missed, log an activity in DayGlint on your iPhone or Watch; it is saved to Apple Health.
What do I need to run DayGlint?
An iPhone with iOS 18 or later. The Watch app needs watchOS 11 or later.
