好日
Kōjitsu
Inspired by 日日是好日
Every day is whole.
Kōjitsu shows you what your life is made of – without streaks, without a score and without daily perfection.
Not in the stores yet – Kōjitsu is currently in closed beta.
One dayA single day
A good day doesn’t have to be balanced.
A day on the bike
Today: movement and rest.
- Nourish & Enjoy at the edge
- Movement at the centre
- Interests & Growth –
- Rest & Recovery clearly
- Connection –
- What mattered today at the edge
Six areas
Ingredients of a day, not a checklist.
Movement 運動
Doing your body some good.
Interests & Growth 学び
Curiosity · Learning · Step by step
Rest & Recovery 休養
Sleep · Pause · Breathe
Connection 絆
Time with people who are good for you.
What mattered today 今日
Sometimes it’s the little things.
Zooming out
The further you zoom out, the clearer your rhythm becomes.
A day is a moment. A week is a pattern.
Some weeks are allowed to be one-sided.
A life is made of many different wholes.
In the app
Log, zoom out, look back.
Prompt, ensō and areas under Today, rhythm under Time, learning journey and waymarks under Perspectives.
Every day is whole.
Not every day has to be balanced. Over time, your life can be.

Your data stays with you
No required account, no sign-up. Kōjitsu stores everything locally on your device first; if you like, it syncs via your own iCloud. There are no servers of our own, no advertising IDs and no analytics SDKs. You can export at any time. Apple Health adds movement and sleep, but is never a requirement.
Details in the privacy policy (in German).
Weekly review
Notice. Place. Take along.
Two to five minutes at the end of a week. No performance review, no targets, no plan with numbers.
What shaped this week?
Example answerPretty sport-heavy – but I was on holiday, so that fits.
Which one-sidedness was deliberate?The evenings alone. I wanted them.
What was good for you?The long Sunday morning with nothing planned at all.
“Next week I’d like to give music a little more room again.”
This sentence quietly accompanies the next week – and may disappear without warning if life turns out differently.
Don’t optimise. Notice. Place. Keep living.
The attitude
Four focal lengths on the same life.
Yōjō and Chūdō are the depth of Kōjitsu, not competing ideas. Think of them as successive focal lengths.
Kōjitsu – The whole day
日日是好日 · “Every day is a good day”
The day is good because it is this day – not because it met criteria.
How do I look at this day?
Yōjō – What we tend
養生 · “nourishing life”
Care means returning, not never stopping.
Why is it worth paying attention to different areas of life?
Chūdō – Measure, not maximisation
中道 · “the middle way”
Balance shows over weeks and years, not on a Tuesday.
How do I deal with emphases and extremes over longer periods?
Ensō – Complete, not perfect
円相 · “circle form”
Your day: open on the right, whole from the morning – the areas only add colour.
What does this circle mean to you?
The difference
The opponent isn’t laziness.
It’s the idea that every single day should be even, productive and optimised.
Typical tracker
Kōjitsu
“What did you get done today?”
“What made your day?”
Completeness has to be earned
Complete from the start
A streak that can break
Rhythm and returning
Score, percentages, rings
Patterns and emphases
daily optimum
long-term measure
deviation = problem
deviation = context, first of all
Red when it was too much
counted, and you add the occasion
gap = setback
gap = a day nothing is known about
“Goal reached” / “not today”
“Today: movement and people.”
A subscription that keeps running
buy once, keep it
No streak that can break
Kōjitsu counts how often something came back, not how long it ran unbroken.
No number that’s meant to rise
The number of completed intentions never colours the day.
No red for drinking
Alcohol is counted neutrally, with no warning colour – Kōjitsu only asks about the occasion.
No gap that counts against you
Untracked days count in no summary. Life happens without the app, too.
Otherwise, at some point in the evening you stop looking at the day and start looking at the day’s balance sheet.
Kōjitsu has no 4-out-of-7, no streak, no score, no percentages, no life-balance value and no “goal reached” – not out of modesty, but because all of that contradicts the core idea.
The learning journey
Read on, if you like.
39 chapters, a good three and a half hours. No quiz, no XP, no unlock order – not a course you have to finish.
The attitude
Kōjitsu, Yōjō, Chūdō, Ensō, rhythm, reflection, your own measure, gaps and returning.
Japanese ideas
Where the terms come from, what they mean in the original – and where Kōjitsu goes its own way.
What research says
Movement, sleep, connection, food, alcohol, habits – with sources and limits.
Care and limits
Kōjitsu is inspired by Zen, Yōjō, Chūdō and Ensō and does not digitise an authentic teaching. Where the app goes its own way – for example in the colour logic of the ensō – the chapters say so explicitly.
Kōjitsu is scientifically informed life reflection, but not a validated score and not a medical application. There is no scientific basis for a universal, even distribution of the areas of life. If you sleep badly or feel exhausted for a long time, you won’t find the answer here – that belongs in other hands.
