BookJab

Reading tracker · Strava for reading

That's how a jab works in boxing.It looks light, like it does no damage.

But jab after jab,it breaks down the guard.

Reading works the same way. A few minutes a day, stacked up,
and one day you're past your own limit.

Handwritten

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.

What does “Strava for reading” mean?

Strava logs your runs and lets you lay your stats over a photo to share. BookJab does the same for reading: a timer logs the minutes you actually read, and you can lay that record over your own photo and share it. It's built for stacking reading instead of miles.

Can I share my reading on Instagram or other socials?

Yes. Stop the timer and you get a record card with the date, minutes read and book title. Save it with a transparent background to lay over your own photo, or save the card as an image, then post it to your Instagram Story, feed, or anywhere else.

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.

What about book covers?

Once you add a book, the app shows its cover inside the app. You can also design your own, and only covers you made go onto the cards you save and share.

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.

Do you support languages other than Korean?

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