About this app

Inkventory is a fast, offline fountain pen and ink collection tracker built for
Android. If you keep more than a handful of fountain pens and a growing
shelf of inks, Inkventory helps you remember what you own, what's loaded right now, and what needs attention.

THE INK SWATCH GRID
See your entire ink collection as a grid of colour swatches, each with a level
ring.
It's the quickest way to answer "do I already own something like this?" - and
it's genuinely nice to look at.

WHAT YOU CAN TRACK
• Fountain pens - brand, model, nib size and material, photo, notes
• Inks - colour, brand, colour family, wetness, shading, sheen, shimmer, level, notes.
• What's loaded - one-tap ink-change logging, so you always know which pen
has which ink.
• Ink levels - new / half / low / empty, updated in a single tap
• Rotation reminders - get notified before a pen sits inked too long and dries out
