App Store brief · the vitrine · for review · September 2026
What a stranger
sees before they
decide
Assume the app is built. This page is every field of the App Store product page, filled in as it would ship — name, subtitle, ten screenshots, description, keywords, price, privacy — with the character limit next to each and the reason for each choice underneath.
The listing is v1: a catalogue and a lending ledger, no money anywhere. Every phone is the live prototype running with selling off. Counters are live — edit any field and the number updates. Dashed chips are the alternatives I didn't pick; argue for them.
THE ONE LINE
Know what you own, and who has it.
Everything on this page is a longer or shorter version of that sentence. If a field doesn't serve it, it's cut.
THE THREE READERS
Hardcore, hobbyist, owner
The hardcore reads the description. The hobbyist reads screenshot one. The owner reads the subtitle and nothing else. Each gets one thing written for them.
01 · The two lines that do the work
Name and subtitle
These two lines are what's indexed for search and what's read on a phone in a list of six other results. The name carries the brand plus the one search term we can't afford to lose; the subtitle carries the promise.

CLCTN – Your Shelf, On Purpose30
The brand alone is five letters with no vowels — nobody types it into search until they've heard of it. So the name spends its remaining characters on the two words people do type: "collection" and "catalogue". Apple indexes the name heavier than the keyword field, which is why these two words don't appear again anywhere else.
Subtitle
under the name · indexed
{{ nSub }} / 30
What you own, and who has it
The shelf, not the spreadsheet30
Catalogue what you collect26
Catalogue, lend, keep track27
The promise, in the words of the person who doesn't identify as a collector: the inherited-crate owner. "Who has it" is the line no competitor can write, because none of them has a lending ledger — it's the differentiator stated as a benefit rather than a feature. "The shelf, not the spreadsheet" is the wittier line and the one I'd pick for a poster; it's second here because it names the enemy instead of the user.
02 · The vitrine
Ten screenshot slots,
nine used
Screenshots are the page. Most people never expand the description, and the first three are visible without scrolling — so those three carry the whole pitch: the shelf, one object, adding one. Then the four things nobody else does. Then trust.
Composition rule: one headline per shot, never more than seven words, in the app's own type on the app's own paper. No feature bullets on the image, no arrows, no device colour choices — the phone frame is ink, like everything else. The tenth slot stays empty on purpose; a listing that ends on "trust" ends stronger than one that ends on "and also".
01 · SEEN FIRST
Your whole collection, on one shelf
Collections as objects, counted. The hobbyist's shot: "mine could look like that".
02 · SEEN FIRST
Every object, front to back
The 3D sleeve does the selling. Three tabs visible: Overview, Details, History.
03 · SEEN FIRST
Add one in ten seconds
Photo first. The lookup toggle is visible — a privacy promise made in the viewfinder.
04
Fields built for your hobby, not for "items"
Real grading scales, steppers, chips. The hardcore collector's shot.
05
Know who has it, and when it's due back
The lending ledger. The one screen no competitor has.
06
Keep the hunt in one place
Wanted objects, dashed. Shareable as a link.
07
From a stamp to a Porsche
All the types in one list — breadth, shown rather than claimed.
08 · TRUST
Nothing is confirmed on your behalf
The review queue. Rare for a store page to show doubt; it's the most honest thing on it.
09 · TRUST
Share one object. No account needed.
What a link looks like to a friend with nothing installed.
Export spec: 6.9" at 1320 × 2868, portrait, headline set in Bricolage Grotesque 800 at 112px, phone at 1.0 scale bleeding off the bottom edge. Same nine shots re-composed for 6.5" and iPad if we ship iPad; no landscape.

Founding price: the full unlock is €19.99 for the first 1,000 collectors, then it rises. One collection of fifty objects is free, with everything in it.
The only field we can change without shipping a build, so it holds the only thing that changes: the price. When the founding tier closes, this line becomes the next price. Never a feature claim here — those belong in the description where they can't quietly drift.
Description
first 3 lines visible, then "more"
{{ nDesc }} / 4000
CLCTN is a catalogue for people who own things on purpose.
It answers four questions about everything on your shelf: what is it, where is it, who has it, and what happened to it. Vinyl, comics, trading cards, coins, stamps, watches, board games, video games, figurines, books, cameras, sneakers, synths, cars — fourteen collection types, each with the fields and grading scales its collectors actually use. Vinyl, comics, coins, board games and watches at launch — one more type every month, each with the fields and grading scales its collectors actually use.
ADD ONE IN TEN SECONDS
Point the camera at the object. CLCTN proposes the pressing, the edition, the year — you confirm it. Barcode when there is one, typing when there isn't. Anything the app guessed stays marked until you agree with it.
BUILT FOR YOUR HOBBY
A comic gets a CGC grade. A coin gets a Sheldon grade and a mint mark. A record gets a Goldmine grade, a pressing and a matrix number. No free-text field where a real scale exists. If nothing fits, build your own type field by field — or keep a mixed shelf where every object carries its own.
KNOW WHO HAS IT
Lend anything with a due date. Both sides confirm the hand-off and the return, so nothing on your shelf changes because someone else tapped something. Everyone you lend to gets a page and a track record.
KEEP THE HISTORY
Lent, returned scratched, serviced, regraded, repaired. Events add to the object's story instead of overwriting a field. Ten years from now you'll know exactly what happened to it.
THE HUNT
A wishlist for what you're after, with priority. Share it as a link: the friend who opens it sees which ones they already own, and you learn nothing until they choose to tell you.
YOURS, PRIVATELY
Your catalogue lives in your iCloud. No account. No server copy of your shelf. Photos stay on your phone unless you ask for a lookup. Export everything as CSV whenever you like. Works offline.
FREE FOR ONE COLLECTION
One collection of up to fifty objects, free, with every feature above. CLCTN Complete unlocks unlimited collections and objects, one-tap import from Discogs, PriceCharting, CollX and Collectr, and exports. One payment. No subscription.
Made by one collector, in the open. Something missing for your hobby? hello@clctn.app
Three lines show before "more": the first sentence is the positioning, the second is the four questions. Nobody should need to tap. Caps headers because the store strips all formatting — they're the only way to make it scannable. The reading order is the three readers in reverse: hobby depth for the hardcore, lending for the hobbyist, privacy and price for the owner who's suspicious of apps. No word in the name or subtitle is repeated here — it earns nothing in search a second time.

The hobbies people search by name, plus the two verbs. "Collection" and "catalogue" are deliberately absent — the name already indexes them. Singulars only; Apple matches plurals for free. Re-cut this field per storefront: the French list swaps "records" for "disques" and drops "boardgame".
What's New
version 1.0
{{ nNew }} / 4000
1.0 — The first shelf.
• Collection types with the grading scales their collectors use
• Add by photo, barcode or by hand
• Import from Discogs, PriceCharting, CollX and Collectr
• Lending with two-sided confirmation and due dates
• Wishlists you can share as a link
• iCloud sync, CSV export, works offline
Something missing for your hobby? Propose a type from inside the app — the most-wanted ones ship as official types, and your objects move over with every value intact.
Written so the 1.1 note can be one line: "Added: Cameras." Each new type is a release note, a community post and a free launch moment — twelve of them if we ship five types first.

PRICE
Free, with one in-app purchase
Free tier is one collection of fifty objects with every feature — a real product, not a trial. The unlock is a one-time purchase, listed on the store page under In-App Purchases so it's visible before download.

€19.99 founding (first 1,000 unlocks or 6 months) → €24.99 → €29.99. Not a subscription. The subscription, if it ever exists, is v2's market data and is not on this page.

PRIMARY CATEGORY
Lifestyle. Where the collector apps and their users are. Alt: Utilities — smaller, easier to chart in, but nobody browses it for a hobby.
SECONDARY CATEGORY
Productivity. Catches the "inventory" searcher — the owner with a crate and a spreadsheet.
AGE RATING
4+. No user-generated content is public; share links are one-to-one.
APP PRIVACY
Data Not Linked to You → Photos or Videos → App Functionality, declared only because the optional lookup sends one frame to identify an object. Everything else is iCloud private database, which is the user's, not ours. Tracking: No. This label is a selling point; screenshot 03 makes the same promise in the viewfinder.
DEVICES
iPhone. iPad and Mac follow when the shelf has a layout for a wide screen, not before.
SUPPORT URL
clctn.app/help — a single page: the four questions, import formats, "how do I get my data out".

05 · Five doors into the same shop
Custom product pages
Apple lets a listing have alternate pages with their own screenshots and promo text, each with its own link. One per launch community: the link posted in the vinyl forum lands on a page where the first screenshot is a record shelf. Name, subtitle and description stay the same — only the first shot, its headline and the promo line change.
VINYL
"Every pressing, every matrix number"
Shot 01 becomes a records collection. Promo: "Import your Discogs collection in one tap. Grades stay Goldmine."
COMICS
"CGC grades, key issues, gaps in the run"
Shot 01 becomes a comics shelf. Promo: "Import from CollX. See which issues you're missing."
COINS
"Sheldon grades and mint marks, ×N"
Shot 01 shows a bulk lot with per-copy grades. Promo: "Built for quantity — coins, not 'items'."
BOARD GAMES
"Know who has your copy of Brass"
Shot 01 becomes the lending screen — this community lends more than any other. Promo leads with the ledger, not the catalogue.
WATCHES
"Service history, on the watch, forever"
Shot 01 becomes the item detail on the History tab. Promo: "Every service, every strap, every owner."
06 · Optional, and I think worth it
App preview, 22 seconds
Autoplays muted before screenshot 01, so it's really screenshot zero. One take, real screen capture, no hands, no music that matters. It answers "what does it feel like" — the one thing stills can't.
0–4s
The shelf. Scroll two collections. The vinyl box tilts as it passes. No text.
4–11s
Add. Camera opens on a record sleeve; the match card slides up with pressing and year; one tap confirms; the object lands on the shelf. This is the "ten seconds" claim, demonstrated in seven.
11–17s
Lend. Open the object, "Lend to…", pick a person, set a date. The row turns dashed. The other phone's confirmation shows as a notification — the handshake made visible.
17–22s
History. Swipe to the History tab: lent, returned, regraded. Hold. Fade to the wordmark on paper. End card copy: "Know what you own."
Full shot list and the clip plan for social live in the video playbook; this is only what goes on the store page.

Notes for App Review
the reviewer reads this, nobody else
No account or sign-in exists; all data is stored in the user's private iCloud database.
The camera is used to add objects. The "Look it up" toggle in the viewfinder sends a single frame to our identification service only when enabled; it is off by default and the sent image is not retained.
To test lending without a second device: add any object → "Lend to…" → pick "Demo contact". The confirmation arrives after 10 seconds in review builds.
The in-app purchase "CLCTN Complete" is a non-consumable; sandbox purchase unlocks a second collection immediately.

DESCRIPTION
Same structure, rewritten rather than translated — "catalogue" and "prêt" carry the same double duty in French. Grading scales stay in their original names; French collectors use CGC and Goldmine too.
08 · Where I want your eye
Three open questions
Q1 · THE NAME
Is "CLCTN" a brand or a handicap?
Five consonants. Unpronounceable on first sight, unsearchable until known, and it's why the name field spends 22 characters explaining itself. My answer: keep it, because it looks like a catalogue number, and once you've heard it said out loud you never forget how it's spelled. I'm aware that's the argument every bad name makes.
Q2 · SCREENSHOT ONE
Shelf first, or object first?
The shelf shows breadth and looks like a product. The object shows the 3D sleeve, which is the only thing on the page that makes people stop scrolling. My answer: shelf, because it answers "what is this" and the object answers "why is this nice" — and the order of those two questions matters more than which one is prettier. You've watched more people scroll store pages than I have.
Q3 · THE FIFTY-OBJECT LINE
Should the free tier's ceiling be on the store page at all?
Naming the limit is honest and pre-empts the one-star "bait" review. It also tells the hardcore collector, before he's downloaded, that the free app isn't for him. My answer: name it, in the last section, in plain numbers — and let the founding price directly above it do the reassuring.
