Reading journal app

One light line a day, like a jab.
It never feels like progress while you're doing it, and then one day you're past your own limit.

How it works

Three moves are all it takes.

Lay today's record over your own photo and save it. Clean enough for your story.

The jab is the simplest move in boxing. One on its own changes nothing, so people write it off.

But one, then another. Land enough of them and the opponent who wouldn't budge finally gives. Reading is the same. The page you read today looks like it changed nothing — but while one line stacks onto another, you quietly shift.

Grand resolutions are short.
Small repetitions last.

BookJab is built for stacking those small repetitions.

FAQ

Frequently asked questions

Is it free?

Yes. The core — logging your reading, saving lines, and decorating to save — is free. We may later offer some advanced features as paid options, but your everyday logging stays free.

How is reading time measured?

With the in-app timer. It pauses automatically when you leave the screen or close the app, so only the time you actually spent reading adds up.

Where is my data stored?

After you sign in (Kakao, Naver, Google, or Apple), your logs and saved lines are stored securely in the cloud (Seoul region) so you can pick up on any device. See our Privacy Policy for details.

Can I read other people's lines?

No. BookJab is a personal reading journal, and we don't show other users' quotes (to respect copyright). Down the road we may surface aggregate data, like which books get saved most.

Can I use it across devices?

Yes. Sign in with the same account and your logs and lines follow you to any device, syncing automatically.

Do you support languages other than Korean?

Right now, Korean and English. The app follows your device's language setting automatically.
