What it does
Bottle Runway — See how many fills remain in each bottle from the pens currently inked, using converter, piston, vacuum, eyedropper, or cartridge capacity instead of a generic millilitre guess. Bottles rank Critical, Soon, or Comfortable.
Rank pen + ink + paper combinations across shading, sheen, dry time, feathering, and bleed. The untested-pair matrix shows what you have not tried yet.
Mix Lab logs custom blends with up to four source inks and exact parts ratios, plus a weighted color preview from your library swatches.
Palette arranges your ink library by hue on a color wheel and flags near-duplicate bottles before you buy another.
Currently Inked rotation tracks which pen holds which ink, with a cleaning-interval alert when a fill has sat too long.
Sample vault, notebook fill bars, nib and ink-property reference, and a stats dashboard stay on device.
Export the full atlas — pens, inks, paper, combos, samples, wishlist, and blend recipes — as CSV through the share sheet.
Fully offline. No account, no subscription, no ads, and no analytics.
