Caliber

Your collection, under glass.

A quiet, considered home for the watches you own. No marketplace, no valuations, no account.

Coming soon to the App Store

The case holds three to start.

The stance

Every other app wants to know
what your watches are worth.

There is a reason for that. A valuation is really a prompt to sell, and the sale is where those apps make their money.

Caliber runs no valuations and holds no marketplace. There is no account to sign into, and no server holding your collection, because there is no server at all. It is a watch case, not a portfolio.

What it has instead is a case, and the watches you own, presented as the objects they are.

The case

Your watches, as you shot them.

Photograph a piece the way you see it, on the wrist, in whatever light you were standing in that morning.

Shoot the dial, the caseback, the clasp, the patina nobody else would notice. Crop and reframe without leaving the app, and set the one that belongs on the cover.

Your photographs stay on your phone at full resolution, kept with the piece, and yours to take out again whenever you want.

A piece you have not photographed yet still shows up as itself, so the case never looks half-finished while you catch up.

The record

Every reference, every paper.

Open a watch and it comes apart. The piece separates into its four strata, crystal, dial, movement, and case, each settling beside the things you know about it.

Warranty cards and receipts scan straight in and stay with the piece they belong to, so the papers live wherever the watch does.

The record shares as a single image, and every watch has one. It is not a certificate and it claims no authenticity, because the app has no way to know either. It says only what your collection knows.

The journal

Worn, not stored.

A collection is not an inventory. It is a rotation.

Log what is on the wrist in one tap, from the app or a Home Screen widget. The rhythm takes shape on a calendar, and on a map of the places the day actually went.

Nothing is captured unless you ask for it. Location has three settings and the default is that Caliber never looks.

A month calendar with per-watch wear dots on the days worn.

Follow the day

Where you wore it, without being followed.

Switch it on and Caliber notes the places you actually spend time, tying each one to the watch that was on your wrist. It records where you stopped, not everywhere you went.

It only notices where you linger, ten minutes at least, and it records a place as you leave rather than as you arrive. Swap watches over lunch and the restaurant you sat in through the swap belongs to both of them.

Add Manually Default

You tag each wear yourself, and nothing is captured for you.

At Each Log

One fix at the moment you log a wear, and nothing more.

Follow the Day

The places you spend real time, with a Reserve membership.

A fresh install captures nothing, and wherever you leave the setting, the places stay on your phone with everything else.

The Places map: a year of wear across the Bay Area, each place pinned with the watch worn there.

The numbers

Your rotation, revealed.

Rotation, cost per wear, the diameter your wrist keeps returning to, and the weekday staple against the weekend pick.

Caliber will also notice that three of your watches take a 20 mm strap, which is the sort of thing you half knew and never counted.

All of it is drawn from what you actually wore, so nothing is estimated, nothing is guessed, and no number appears before you have earned it.

Two appearances

An after-hours case, and a daytime one.

Caliber is obsidian and gold after dark, and alabaster and bronze by day. This is not one palette dimmed, but two, each drawn for the light it belongs in.

Pick one and it stays picked, or leave it on Automatic and let the case follow your device from morning into evening. The Home Screen widget follows the same choice, so your collection never looks like two different apps.

Even the record's cardstock changes with it, from gold foil after dark to a debossed bronze by day.

The collection in the dark appearance: obsidian and gold. The same collection in the light appearance: alabaster and bronze.

Dark Light Automatic

The catalog

It fills in what it knows.

Type a reference and the specifications arrive with it: case, diameter, dial, movement, caliber. The data entry that sinks every other collection app never begins.

Enter a piece the catalog has yet to learn and it stays yours, complete, exactly as you typed it. When a later version learns that reference, Caliber fills the blanks you left behind and never touches a value you entered.

The catalog grows. Your watches grow with it.

Yours to keep

Come in whole. Leave whole.

Bring a collection in from the spreadsheet you have been keeping for years. Caliber reads it, including the column names collectors actually use.

Take everything out whenever you wish. Watches, photographs, documents, and every logged wear, in one archive you can open without Caliber.

Export is free forever and is never members-only. A collection you cannot get out of an app is not yours.

Settings, Your Data: Export Collection and Import Collection, with a note explaining that nothing leaves the app unless you share it.

The contrast

Our word.

No marketplace

Your collection is not a sales funnel.

No valuations

A live price is only useful to someone who is selling.

No account

There is nothing to sign into.

No server

Your collection lives on your phone, and only there.

No analytics

The App Store label reads Data Not Collected.

No ads

Not now, not later, not as a tier.

A public collection and a shipping address is a burglary map. Caliber holds neither.

Caliber Reserve

Membership for the whole collection.

The case holds three to start, and those three are whole. Records, papers, the journal, the widget, the calendar, the map, the milestones, and export. Nothing about them is a sample.

Annual

$34.99 a year

The first two weeks are complimentary.

Lifetime

$79.99 once

A founding membership. The price rises to $99.99 when sync arrives.

Open the Full Case

Reserve adds the full case, the deeper numbers, and Follow the Day. Everything already in your case stays yours either way. Viewing, wearing, and export are never members-only.

Questions

Asked and answered.

Do you show what my watches are worth?

No, and that is not an oversight. Live valuations exist to tell you when to sell, and selling is somebody's business model. It is not ours.

What happens to my watches if I stop paying?

Nothing. Every watch already in your case stays viewable, wearable, editable, and exportable, forever. Membership only ever governs adding beyond three, and the member extras. Your collection is never held hostage.

Lifetime is $79.99. Other apps charge less.

They do, and some of them also bill separately, and forever, for the sync that a Caliber membership will include, so the multi-year number is the one worth comparing. If the answer is still no, the annual is $34.99 with two complimentary weeks, and the free three are genuinely whole.

Do I need an account?

There is no account and no sign-in screen anywhere in the app. We could not identify you if we tried.

Can I get my data out?

Yes, all of it, free, and forever: watches, photographs, documents, and wear history, in one archive. It is worth testing on the first day rather than the day you need it, and an app that makes it difficult has told you what it thinks your data is for.

Is my collection backed up to the cloud?

Not yet, and we will not pretend otherwise. Caliber is local-first today, which is why the privacy label reads the way it does. Sync is coming, and when it arrives the lifetime price rises. Until then, export is your backup and it is one tap away.

Will my whole collection fit?

Yes, with a Reserve membership, and there is no upper limit. The catalog is a curated set of canonical references rather than a market database, so a piece it has yet to learn goes in by hand and looks exactly as complete. When the catalog learns it later, your record fills itself in.
