Description
A quiet iPhone app for fountain pen and ink collectors. Every ink is drawn as a bottle at its real fill level, so a collection looks like a collection rather than a spreadsheet. Each pen gets a page with your own photographs, and the app keeps track of which ink is in which pen right now. No account, no server, no analytics, no subscription: it syncs through your own iCloud and you pay once. Imports from Fountain Pen Companion; exports everything, free, forever. Made by one person in Tallinn.
