Small utilities, built one at a time.

ridif is slang in Persian — shorthand for a word that means in order, or organised. Fitting, because ridif.app is home to a growing set of simple, free web tools for household and community life — the kind of everyday organising that deserves better than a group chat and a spreadsheet. Each tool lives on its own subdomain and does one job well. New ones are added to the row as they're built.
