Koinos for web

Your lists, already open.

Everything Koinos does, with nothing to install.

Create a list, organize it, invite people, and watch changes appear as everyone checks things off.

Works in any modern browser.

All your lists on the left. The one you’re using on the right.

More screen means two panes, not more buttons.

Your lists stay organized in one pane while the list you’re using remains open in another. Move between groceries, packing, chores, and projects without losing your place.

Shared links

A link is all they need.

When someone opens a Koinos invitation, the shared list appears directly in their browser. They can understand what they’re joining before creating an account. When they’re ready to contribute, signing in returns them to the same list.

Joining and collaborating is always free.
Small windows

Squeeze it into a corner of the screen.

Drag the window narrow and the two panes fold into one column, still centered on the checklist.

Half a laptop screen is plenty.

One account

Everything stays together.

The web app uses the same Koinos account and the same lists as the mobile app. Add something from your computer and check it off later from your phone.

Nothing to export, transfer, or reconcile.

Nothing to install.

Make a list now, and send it to someone before you close the tab.
