Chase the tasseikan.

Emergency unlock I'm choosing not to chase my goal right now

You pick up your phone to check one thing. Twenty minutes later, the goal you care about is still waiting right where you left it. Tasseikan puts the next small step right where the scroll used to be.

How it works

Four steps to your next small win.

Set it up once in the morning. After that, Tasseikan steps in only at the moment you'd usually drift.

Say what you want.

Everything starts with one question: what do you want to achieve? Pick a goal or write your own. Tasseikan turns it into small daily tasks you can actually do.

Choose what pauses, and when.

Pick the apps that pull you away and a window, like 7 to 11 in the morning. Calls, maps and anything you rely on stay open. When the window ends, everything opens on its own.

Do one small thing.

Reach for a paused app and Ganbatte hands you the task instead. Prove it the way that fits:

A quick photo A partner's OK Apple Health

Feel it.

The seal stamps 達成, your apps open early, and your streak grows by one. That quiet glow is the tasseikan. It's the reason you come back tomorrow.

山となる

Dust, piled up, becomes a mountain.

Nobody climbs in one leap. Tasseikan counts every small thing you finish and stacks it where you can see it. Keep scrolling and watch a year of single days add up.

FAQ

Good questions.

What does tasseikan mean?

達成感 is Japanese for the feeling of accomplishment, that quiet glow when something is finally done. It's what the app helps you chase, one small win at a time.

Will it lock me out of something I need?

No. You choose which apps pause and when. Emergency unlock is always one tap away, and every window ends on its own.

How does it know I did the task?

You pick per task: a before and after photo, a partner who confirms it, or a connected app like Apple Health for workouts.

Is it really free?

Yes. Free includes a Focus Rule, the starter library, streaks and Hansei. You'll use the app before you ever see an offer to upgrade.

What if I miss a day?

Nana korobi ya oki: fall seven times, stand up eight. You pick back up tomorrow with no guilt.

When can I get it?

Tasseikan is coming to iPhone first, with Android after. Join the waitlist and you'll get one email on launch day.
