InkAtlas is the offline companion for fountain pen enthusiasts. Track every pen in your collection, every ink bottle with its swatch color, and the paper you write on — then log how each pen, ink, and paper combination actually performs. **Bottle Runway (New in 2.0.2)** See how many fills remain in each bottle from the pens currently inked with that ink. Runway uses that pen’s filling mechanism — converter, piston, vacuum, eyedropper, or cartridge — not a generic 0.9 mL guess. Bottles are ranked Critical, Soon, or Comfortable, and an estimated days-left figure appears when a cleaning cadence is set. **Your pen + ink + paper combinations, ranked** Log combos with five-dimension ratings: shading, sheen, dry time, feathering, and bleed. Sort by any dimension to surface your best pairings at a glance. The untested-pair matrix shows which combinations you haven't explored yet. **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 swatches so you can identify each blend at a glance. Blend recipes are included in the full CSV export. **Palette — Hue Wheel** See your entire ink library arranged by hue angle on an interactive color wheel. Tap any ink dot to inspect its hue, saturation, and brightness values. A color-family grid identifies which hue families you've covered and which are gaps in your collection. Near-duplicate inks — those within 12° of another at similar brightness — are flagged so you can spot overlapping bottles before buying. **Currently Inked rotation** Track which pen holds which ink right now. Set a cleaning-interval alert and InkAtlas flags any pen that has been inked past your threshold. **Ink Sample Vault** Log vials and ink samples with status (untested, testing, loved, pass) and a star rating. **Notebook tracker** Record which paper, pen, and ink you're currently using in each notebook, with a fill-bar showing how much paper remains. **Reference tabs** 80+ ink property tags (shading, sheen, shimmer, permanence, behavior) with live canvas demos. Nib width reference from Extra Fine through Music nib with visual stroke previews. **Stats dashboard** Rating distribution histogram, dimension averages, brand breakdowns. **CSV export** Export your full atlas — pens, inks, paper, combos, samples, wishlist, and blend recipes — as a single CSV file through the iOS share sheet. **Fully offline. No account. No tracking.** Everything is stored locally on your device using SwiftData. InkAtlas has no network requests, no analytics SDK, and no account requirement. ## Version history (last 5 releases) ### 2.0.2 — 2026-08-19 Version 2.0.2 adds Bottle Runway, a fountain-pen fill planner unique to this app. See how many fills remain in each bottle from the pens currently inked, using that pen’s filling mechanism (converter, piston, vacuum, eyedropper, cartridge) instead of a generic millilitre guess. Bottles rank Critical, Soon, or Comfortable. Open it from the Atlas card or More. Native tabs replace the old overlay dock. ### 2.0.1 — 2026-06-24 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. ### 2.0 — 2026-06-21 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. ### 1.3 — 2026-06-15 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. ### 1.2 — 2026-06-14 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. ## More apps by Robert Corbin - [Daily Word Journey](https://appshunter.io/ios/app/daily-word-journey/id6761548266) - [Hush Secret Text](https://appshunter.io/ios/app/hush-secret-text/id6761658175) - [Renew Guard](https://appshunter.io/ios/app/renew-guard/id6761755447) - [Receipt to PDF](https://appshunter.io/ios/app/receipt-to-pdf/id6761782025) - [Route Your Pay](https://appshunter.io/ios/app/route-your-pay/id6761783719) - [Tip Arbiter](https://appshunter.io/ios/app/tip-arbiter/id6761786879) All apps by Robert Corbin: https://appshunter.io/developer/1890247992 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
