Mood journal & ColorWalk for iPhone
Tap a cloud to note how you feel, then turn an ordinary walk into a hunt for color. Gentle, private, and a little bit silly.
Free to download · iPhone · iOS 18 or later

Check in
Pick one of seven cloud moods — the same scale as State of Mind in Apple Health. Add a few feeling words, what it’s about, and a note if you like.

ColorWalk
Pick today’s color — or roll the dice — and photograph everything you find in that shade. Each walk keeps its time, distance and route, and your photos become a little collection.


On your Home Screen
Keep today’s cloud, your week and your latest ColorWalk on the Home Screen or Lock Screen. Pick a widget theme and an app icon to match.
