About rujebin

rujebin is a personal project based in Korea. It builds web tools that make small but surprisingly time-consuming decisions easier, like picking a lunch spot or splitting the bill after a night out.

How we build

• No sign-up. Open the link and start using it.
• Made for phones. We design for a group sharing one phone at the table, or each person on their own.
• Your data stays with you. Names and amounts you type are kept in your own browser, not on our servers.
• Free. Every tool is free. Ads may appear to cover running costs.

What we've made so far

• rujebin pick: Pick Together, lunch picker, ladder game, who pays, Russian roulette, bill splitter, finger picker
• Korea ferry timetable: ferry schedules in Korea (Korean only)

Our guides are currently in Korean only.

We'd love your feedback

Ideas like "I wish there was a tool for this" or "this part is confusing" are always welcome on the Contact page. We add tools one by one, based on what we needed and what you tell us.
