How do cells get filled?
Photograph the sky now and the cell for the current time fills with the colour you caught. If it comes out different from what was expected, it goes in anyway — that really was the sky at that hour.
The rest of your collected skies count by colour: if one is close enough to today's sky colour for a given time, it fills that cell.
A cell that was full yesterday is empty today
That's because the board shows today's sky colours. The colours of the forty-eight cells are set again every day for the season and the weather, and every day the app asks again whether your collected skies are close to them. So some days the board is nearly full and some days it looks nearly empty.
Your photos haven't gone anywhere. Every sky you've collected is still in Records, and in Palette if you'd rather see them in colour order.
Filled cells keep fading
That's on purpose. A photo keeps its true colour for a week, then fades slowly over the next eight weeks. It isn't deleted, and it never fades away completely — photograph the sky at that time of day again and it's back to full colour straight away.
Does the colour have to match?
No. There's no pass or fail. Every photo you take is saved, and the grey of an overcast day is that day's sky colour too.
Why does it ask for my location?
Only to line up the reference colours with the actual sunrise and sunset where you are, and to fetch today's forecast. Accuracy is kilometre-level, and the coordinate is never attached to a photo. The app works fine if you say no (it uses Seoul's colours instead). The details are in the Privacy Policy.
Where do the expected sky colours come from?
They blend the position of the sun (sunrise and sunset for that date and place) with Apple Weather's hourly cloud and rain forecast. If the forecast can't be fetched, the app draws a clear-sky reference instead.
Deleting a photo
Open the photo and tap Delete, or swipe left on it in Records. That removes it from your device and from your iCloud. If you delete the app, the copy in your iCloud stays, so your skies come back when you reinstall.
Requirements
iPhone with iOS 17.0 or later. Portrait only. The app's screens are in Korean.
