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. No single blow takes the round — hundreds that never stopped do.
Reading is the same. The page you read today looks like it changed nothing. Today feels just like yesterday.
But one page turns into the next, one line stacks onto another — and quietly, without noticing, you shift. Look back one day and you're standing somewhere you didn't start.
Grand resolutions are short.
Small repetitions last.
BookJab is built for stacking those small repetitions — log today's page, gather the lines that stay with you, and dress one up cleanly whenever you want to share it.
How it works
Three moves are all it takes.
- 01
Log
Track the time
Start a session and the timer runs. Step away from the screen and it stops on its own, so only honest minutes add up.
- 02
Save
Keep the line
Drop a line that lands straight into its book. Saved with the page number, ready to pull back up anytime.
- 03
Share
Send it out
Dress a quote up clean enough for your story. A transparent overlay lets it sit anywhere.
Features
Marks that add up, made tangible.
02Save
Save your lines
Tuck a line that moves you into its book. Stored with the page number, ready whenever you want it back.
03Decorate
Decorate & share
As a transparent overlay, or a moss- or ink-toned card. Clean enough to post straight to your story.
04Quiet
No noise
No one else's feed, no like counts. Just you, your shelf, and your lines.
05Bilingual
Korean & English
Detects your device language and shows the interface in Korean or English.
06Private
Yours alone
We collect as little as possible. Export or delete your data whenever you like.
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.
