This update sharpens the interface: the iPad layout now uses a centered, comfortable reading width instead of stretching edge to edge, plus small display fixes. iPhone is unchanged.

InkAtlas 2.0 — a pro upgrade for ink and pen collectors, still 100% offline. • Color Match: extract the dominant color from a swatch photo on-device, rank the closest inks you already own by Delta-E, and flag dupes — plus a hue-family browser. • Try Next: a scored recommendation over your untested pen×ink matrix, weighted by affinity, novelty, and expressiveness. • Ledger: bottle volume and price to cost-per-mL, remaining value, and page/fill/word yield by nib. • Insights: hue distribution, acquisitions over time, dimension averages, and spend by brand (charts). • Paper reference with a GSM scale and a paper-dependent dry-time bench. • Shareable swatch cards and a printable collection PDF. No account, no network — every pen, ink, and swatch stays on your device.

Version 1.1 adds two major new features for fountain pen enthusiasts who mix inks and want a clearer view of their collection. Mix Lab - Ink Blend Logger Record your custom ink blends with up to 4 source inks and exact parts ratios. InkAtlas computes a weighted color preview from your library so you can identify the blend at a glance. Each blend entry stores your notes, the ratio string (e.g. 3:1), and whether you used the computed color or set your own swatch. Blends are included in the CSV export. Palette - Hue Wheel Browse your entire ink library arranged by hue angle on an interactive color wheel. Saturation sets the dot's distance from the center. Tap any dot to inspect the ink's hue/saturation/brightness values and property tags. A color-family grid shows which hue families (Red, Orange, Yellow, Green, Teal, Blue, Violet, Pink) you have covered and which are gaps. Near-duplicate inks - those within 12 of another with similar brightness - are flagged with a gold badge so you can spot overlapping bottles. CSV export updated - The full atlas export now includes a dedicated BLENDS section with one row per blend, listing all ingredients and their ratios.

InkAtlas 1.2 adds a Currently Inked rotation tracker with per-pen cleaning-interval alerts, an Ink Sample Vault (6-state status, tasting notes, ratings), a Wishlist with priority and price, and CSV export of your whole atlas. Fully offline fountain-pen tracking — no account, no tracking.

Updated the app icon with a unique futuristic high-definition design and refreshed the App Store build.
