IRODORI: Fountain Pen Inks

IRODORI is a notebook for fountain pen ink lovers - a place to keep your collection as a box of colored jewels. Labels never show the real color. IRODORI reads the color straight from a photo of your swatch, lines every ink up by hue, and lets you browse, compare and choose at a glance. Sorted by color, searched by color - Your inks appear in a hue-sorted grid that is a pleasure just to look at - Photograph a swatch and the app extracts its representative color automatically; tap anywhere with the eyedropper to fine-tune it - Ask "which of my inks is closest to this color?" and get them ranked by CIEDE2000, the industry-standard color difference formula built around human perception - Filter and search by color category, brand, rating, and ownership status Search by reading, too - Give each ink and pen a reading, in kana or in romaji - whichever you prefer - Find an ink with a kanji name by its reading. Notes are searched as well - Pens are searchable by model, reading, brand and note Know what is in each pen - Track which ink is currently inked in which pen - See how many days it has been since filling, with a badge when cleaning is due - Cleaning a pen turns the entry into history, so you can look back on what you used and when Your pens, too - Record nib width (EF to BB and specialty nibs), nib material, filling system, purchase date, shop, and rating - Usage and cleaning history per pen Same collection on iPhone and iPad - Sync your collection across your devices with iCloud; turn it on or off any time in Settings - Syncing goes to your own iCloud account.
