Introduction: The One Question Pen Apps Never Answer
Every fountain pen collector knows the moment. You reach for a pen expecting a wet, saturated blue, uncap it, and find either nothing at all or a nib crusted shut by an ink that has been sitting there since spring. The collection is fine. The record-keeping is the problem.
That is the exact frustration Inktend was built to solve. Rather than treating a pen collection as an archive to be catalogued, Inktend treats it as a rotation to be tended. It is a fountain pen and ink tracker for iPhone that opens on the pens currently filled — not on a sortable inventory buried three menus deep.
This article walks through what Inktend does, who it is for, how its catalog and web tools work, and why its approach to data ownership stands out in a category dominated by account-gated services.
What Is Inktend?
Inktend is an iOS app and companion website for fountain pen users who want to keep track of three things: which pens are inked right now, which inks they own, and what they have filled over time. The tagline on the homepage sums up the philosophy in three words — tend to your inks.
Key facts at a glance:

The app is the work of a single developer who is also a collector — a detail that shows up in the product decisions more than in the marketing.
The Core Idea: Currently Inked, Front and Centre
Most collection apps open on inventory. Inktend opens on the desk.
The home screen lists every pen that is filled at this moment, with three pieces of information for each: which ink is in it, how many days it has been inked, and roughly how much ink is left. A pen at day 5 sits quietly. A pen at day 23 gets a gentle amber flag suggesting it is time to clean the nib before the ink dries in the feed.
That 21-day threshold is a small design decision with an outsized effect. It converts a maintenance chore that most people forget into an ambient signal they can act on. Crucially, the app does not gamify it — no streaks, no badges, no guilt-tripping notifications. As the site puts it, the flag is a nudge, not a scorecard.
Your full inventory has not gone anywhere. It is simply one tap away instead of being the first thing you see.
Why This Matters for SEO-Minded Readers and Real Collectors Alike
Searches like “currently inked app”, “fountain pen ink log” and “which pens are inked” reflect a genuine behavioural need rather than a filing need. Inktend is one of the few apps whose information architecture is organised around that need directly, which is why it tends to resonate with active users rather than archivists.
Logging a Fill in Under Ten Seconds
Adoption of any tracking tool lives or dies on friction. Inktend’s fill flow is two steps: pick a dry pen, pick an ink. Done.
There is one lovely flourish. If a particular pen-and-ink combination has never been recorded before, the app calls it out — first time together. In a hobby where half the pleasure is discovering how a specific nib renders a specific ink, that is a well-judged piece of delight that costs the user nothing.
Over time, these logged fills build into something more useful than a list: a history of what you actually reach for, as opposed to what you own.
The Ink Catalog: 13,792 Inks, 713 Brands
Adding a bottle should not mean typing a name, hunting for a hex code, and guessing at a colour. Inktend ships with a built-in catalog so that most additions are a search-and-tap.
The catalog is notable for two reasons.
First, the ordering. Inks are sorted blacks and greys first, then blues and navies, then the rest of the spectrum — the order collectors actually use when they scan a shelf. It is a small taxonomy choice that makes browsing feel native rather than alphabetically arbitrary.
Second, the honesty about data. Every hex value is described as verified rather than invented, sheening inks are flagged rather than guessed at, and the site carries a standing disclaimer that on-screen colours are close digital approximations, not calibrated matches. Pen fill systems and nib options are marked Verified only where a specific model has been individually confirmed. In a category where padded databases are common, that restraint is a credibility signal.
The catalog spans the brands you would expect — Pilot Iroshizuku, Sailor, Diamine, J. Herbin, Robert Oster, Noodler’s, Lamy — alongside a long tail of regional makers, limited editions, shop exclusives and shimmer lines.
Swatch Photo Matching
Manufacturer swatches are notoriously optimistic. Inktend lets you photograph a swatch on your own paper and matches the colour to what you actually see. For anyone who has ordered an ink based on a product image and been surprised, this alone justifies the download.
Ink Lab: Free Web Tools You Don’t Need the App For
One of the smarter aspects of Inktend’s strategy is that the website is genuinely useful on its own — a content moat that also happens to be excellent for organic search.
- Ink Lab colour finder — Pick any colour from a picker and match it against the full catalog. Useful when you have a hex value from a brand palette, a photograph, or a colour you simply want to write in.
- Ink comparison tool — Put any two inks side by side.
- Printable swatch sheet — Select up to twelve inks and print a clean reference page.
- Pen catalog — 1,784 pen models with fill system and nib data.
- Brand directory — Brand-level browsing with histories.
- Starter kit quiz — A guided path for people buying their first fountain pen.
- Journal — Ink deep-dives and paper-pairing notes.
Each of these is a legitimate landing page for a distinct search intent, which is the kind of structure most small app sites never bother to build.
Stats, Year in Ink, and Shareable Cards
Inktend quietly tracks totals in the background: fills logged, pens owned, inks owned, and your most-reached-for bottle. At the end of the year that becomes a Year in Ink recap.
There is also a Currently Inked card generator, explicitly designed for sharing on r/fountainpens and similar communities. No account, no watermark, no sign-up wall. For a hobby whose culture runs on weekly “currently inked” threads, meeting people where they already post is a sensible move — and a quietly effective distribution channel.
Data Ownership: The Strongest Argument for Inktend
This is where Inktend separates itself most sharply from the field.
- No account. You do not create a login to use the app.
- No server. Your collection lives on your device.
- Full export, any time. Every pen, every ink, every fill, in a plain file you can open in a spreadsheet.
- One-tap import. Coming from Fountain Pen Companion or any CSV export, migration is a single action.
The developer’s own framing is blunt: your collection is yours, full stop, and leaving should be as easy as arriving. For anyone who has watched a beloved niche app get acquired, sunset, or paywalled, that is not a small promise. It is arguably the single most important feature in the app.
Pricing: Free, With Optional Pro
Inktend is free to use. There is a one-time Pro purchase for people who want to support development further. No subscriptions. No ads. No algorithmic feed suggesting which ink you should buy next.
That model matters for a hobby app. A collection tracker is something you want to still be using in ten years, and subscription fatigue is the most common reason people abandon tools they otherwise like.
Who Inktend Is For
Ideal for:
- Collectors who rotate through several inked pens at once and lose track of them
- Anyone who has ruined a nib by leaving ink in it too long
- Ink buyers who want a reliable colour reference before ordering
- Users migrating away from account-based trackers
- People who post currently-inked updates in pen communities
- Beginners who want a catalog and a starter-kit path in one place
Less suited to:
- Android users, for now — though there is an interest list
- Anyone wanting a social network with feeds, follows and likes; Inktend deliberately has none
- Collectors who need cloud sync across multiple devices, given the local-first design

Frequently Asked Questions
Is Inktend free? Yes. The app is free to use, with an optional one-time Pro purchase and no subscriptions.
Do I need an account? No. Inktend does not require an account and stores your collection locally on your device.
Can I import from Fountain Pen Companion? Yes. Import from Fountain Pen Companion or any CSV file takes a single tap.
Can I get my data back out? Yes. You can export every pen, ink and fill you have logged as a plain file you can open in a spreadsheet.
Is there an Android version? Not yet. There is an email list for people who want to be notified about Android and other releases.
How big is the ink catalog? The Inktend catalog covers 13,792 inks across 713 brands, alongside 1,784 pen models.
Are the ink colours accurate? They are close digital approximations rather than calibrated matches. Inktend states this explicitly and lets you photograph your own swatches for a more truthful reference.
Does Inktend remind me to clean my pens? Yes. A pen inked for 21 days receives a quiet amber flag suggesting a clean, and the app also nudges you when a favourite has sat dry for too long.
Final Verdict
Inktend succeeds because it starts from a question rather than a data model. Not what do you own, but what’s inked, right now? Everything else — the catalog, the swatch matching, the Year in Ink recap, the shareable cards — is arranged around that rhythm rather than competing with it.
Add to that a serious commitment to data ownership, a one-time price rather than a subscription, and a set of free web tools that would justify bookmarking the site even if you never installed the app, and the result is one of the more thoughtfully designed niche tools available to fountain pen users today.
If you have ever uncapped a pen and been surprised by what came out — or by what didn’t — Inktend is worth an evening of your time.
