Can't remember which ink is in which pen?
“I usually have a dozen inked pens in rotation, so it's hard for me to remember.” — real buyer, https://www.fountainpennetwork.com/forum/topic/374204-how-do-you-keep-track-of-ink-in-pens/
A 'currently inked' tracker is simply a running list of which pens have ink in them right now, what ink each one holds, and the date you filled it. The method matters because rotation is the whole problem: once you keep a dozen pens inked at a time, memory stops working. You uncap a pen and genuinely cannot recall whether it is one teal or another. A good tracker turns that guesswork into a single glance.
The two fields that make it actually useful are the ink name and the fill date. The ink name kills the 'which teal did I load?' moment. The fill date is your early-warning system: most inks left sitting in a pen start to dry or harden after a few weeks, so a tracker that surfaces a fill date lets you flush before a pen dries up rather than discovering a clogged feed weeks later. Pair that with a last-cleaned date and you can see at a glance which pens are overdue for attention.
Fountain Pen Studio is built around exactly this rotation. Every pen carries its current ink and fill date, the Dashboard shows your whole 'Currently Inked' rotation sorted by last use, and the maintenance panel flags pens that have gone too long without a flush so they never dry out unnoticed. It is a one-time purchase that runs fully offline as a single-file app, with no account and no subscription, and everything stays on your device.
