A mood tracker for every part of your day
Most mood trackers ask for one entry a day. Dayfuku lets you check in whenever your mood changes, in a single tap, so a rough morning and a great evening both count.
One entry a night flattens your day
Think of a day that started badly and ended well. Asked about it at bedtime, most of us shrug and say “okay.” Psychologists call this the peak-end rule: we judge an experience mostly by its most intense moment and by how it ended, and the rest fades.
That’s a problem for a mood tracker. If you only ever record the bedtime verdict, the rough morning and what fixed it never make it into your data, and those are exactly the moments that explain your mood.
-
Rough at 8:05 AM
Overslept and spilled my coffee.
-
Okay at 1:30 PM
Quiet lunch, back to work.
-
Great at 7:10 PM
Evening run by the water, then finished my book.
Logged once at night, this day is just “okay.” Logged as it happened, it shows what turned it around.
How it works
One tap, as often as you like
- Tap how you feel. The first tap on a mood saves the check-in with the current time. Fuku reacts, and you’re done.
- Add what you were doing. Your six favorite activities are right there, ordered by what you usually log at this time of day.
- Add a note or photo if you want. Dictate a line, attach photos (Dayfuku Pro), or change the time and place.
- Read the whole day. Check-ins line up in order, and the day overview combines them with your steps, sleep and places.
Widgets
Even faster from your Home Screen
Checking in several times a day only works if it takes no effort. With the Dayfuku widget, you tap a mood on your Home Screen and it’s saved to today without opening the app. There are Lock Screen widgets too.

Tips for checking in more than once
Two to four a day is plenty
You don’t need to log every hour. A check-in when something shifts, plus one in the evening, already shows the shape of a day.
Tie it to things you already do
After your morning coffee, after lunch, before bed. Reminders can nudge you at those times until it sticks.
Log the moment, not the verdict
Write down how you feel right now, not how the day is going overall. The patterns come from many small, honest moments.
Keep it short
A mood and an activity is a complete check-in. Add a note or a photo only when there’s something you want to remember.
What you learn from more check-ins
Every check-in links a mood to what you were doing at that moment. With one entry a day, a good evening run and a bad morning commute land in the same entry, and it’s hard to tell which one mattered. With several, Dayfuku can see that runs tend to come with good moods and commutes with rough ones.
Over a few weeks, Insights show your mood trends and a streak and heatmap for each habit. With Dayfuku Pro, Fuku also points out in plain words which activities tend to come with your better days, and how your sleep and steps line up with your mood.

Your first check-in takes a single tap. Fuku will take it from there.
