Collection tracker & swatches
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Turn your fountain-pen collection into a color wall. Track inks, pens, and what is filled today — private, organized, and on your device.
Your inks deserve better than a spreadsheet. Nibful turns your collection into a wall of swatches — every ink in its own colour — alongside your pens and what's loaded in each one.
WHAT YOU CAN DO
• Build a swatch library — record each ink's colour and see your whole collection as a palette
• Catalog your pens: brand, model, nib, material, and notes
• Track what's currently inked — which pen has which ink, right now
• Keep a wishlist of the pens and inks you're still after (Premium)
FREE
Free includes up to 15 inks and 5 pens; Premium unlocks more items, photos, wishlist, value tracking, and CSV export.
PREMIUM — 7-DAY FREE TRIAL, THEN $6.99/MONTH OR $39.99/YEAR
• Unlimited pens and inks
• Photos — add a written swatch to each ink and a shot of each pen
• Wishlist and collection value, with a running total
• Export your collection as a file
• Cancel anytime from your Apple ID settings
PRIVATE BY DESIGN
Everything stays only on your device. Nibful never uploads, syncs, shares, or sells your data. No account needed.
Nibful is a personal collection log. Recorded swatch colours are approximate and depend on your screen — not a colour-matching standard.
