Who owes whom?

Kidanki exists in two versions: the "anonymous" version where one can create and share an expenses sheet without signing in; the "connected" version where one signs in and can manage several expenses sheets and several groups of people. Today, version 3 for anonymous has been released! It works on mobile, tablet and desktop screens, it's fast and it couldn't be any simpler. Here are some screenshots: Creating a new expenses sheet List of expenses on a mobile screen List of expenses on a tablet screen List of expenses on a desktop screen List of debts on a mobile screen Expenses sheet settings on a tablet screen

Who Owes Whom was first released in 2008 and hasn't changed much since 2011. To my surprise, this tool is still used by many people. I now have the motivation to begin a new version that will fix 2 main issues: make the site mobile friendly make it simple, delete features nobody uses like the concept of debts you can simplify manually.

Major technical update that changed datastore structure (debts can be parent of account rather than group).

When creating an expenses sheet anonymously, the user can choose to be sent an email with the link to the expenses sheet.

After many unwanted deletion of expenses sheet, bin for expenses sheets has finally been implemented. It is now impossible for users to delete directly an expenses sheet: the sheet is marked as deleted and automatically destroyed 30 days after its last edition, unless the user recovers it before. The action of deleting is now more coherent with other actions as it is undoable.
