## What is Testacorvo?

TESTACORVO is a companion for watch collectors and anyone drawn to horology: a catalogue, a school and a private collection journal in one self-contained app.

THE CATALOGUE

962 watches across 100 houses, every one illustrated by hand rather than photographed. Current lines and discontinued icons, each with its reference, its specifications, and the history that earned its place. Browse by house, trace origins on a hand-drawn world map, or follow the schools of watchmaking from valley to valley.

THE MOVEMENT, IN 3D

Pull a mechanical calibre apart layer by layer. Drag to rotate, tap a part to name it, and follow power from the mainspring through the going train to the balance. A second model explodes a complete watch: case, dial, bracelet and all.

THE ACADEMY

A school of horology in wings: anatomy, movements, history, engineering and vocabulary. Short lessons, honest diagrams, and diplomas when you have earned them. Complications unlock along a scroll of gears, from GMT to tourbillon. Learn how a watch actually keeps time. Lessons can be read aloud, by a choice of three narrators.

ON THE WRIST

Set a watch on the wrist and the hours bank as you wear it. The WatchBox keeps what a collection truly costs and returns: hours worn, cost per hour, estimated value, pieces owned, admired and let go. Milestones mark the story your collection tells: the first three houses, three days running, a discontinued piece kept alive.

YOUR WATCHES, YOUR PHOTOS

The drawings are where every watch starts, not where yours has to stay. Open any piece in your WatchBox, choose a photo of it, on the wrist or on the desk, and your own picture takes the place of the illustration throughout the app.

AND THE REST

Strap recommendations matched to what you own. An accuracy log for every watch, with each reading judged against the tolerance its calibre is held to. Genuine-or-counterfeit guidance for every house, and model-by-model tells for 133 of the most-faked references. Valuation papers fit for an insurer. Twenty-four themes, unlocked through use, from warm black to sterling to paper.

PRIVATE BY DESIGN

No account, no ads, no analytics. The only thing that ever leaves your phone is a rounded location for the weather, if you turn it on. Everything else runs on your device; what syncs moves only through your own private iCloud. We never see it. There is nothing to see it with.

FREE TO BEGIN

Two watches come fully unlocked, every model is open to browse, and the whole first module of the Academy, The Watch, is free. TESTACORVO Premium opens everything: $49.99 a year, or $119.99 once, forever. No other purchases, no consumables, nothing that nags.

Precision spares no second.

TESTACORVO Premium is available as a yearly auto-renewing subscription at $49.99, opening with a 14-day free trial, or as a one-time Lifetime purchase at $119.99. A subscription renews automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in your Apple ID settings at any time.

## Version history (last 5 releases)

### 1.0.5 — 2026-11-09

Anatomy Rush in 3D. The Bench's sixty-second drill now asks every part on the 3D movement and watch: turn it, zoom in, open it up, and touch the part itself.

Rate history. In Maintenance, Rate and regulation now has a History button for every watch: each reading with its date, judged against the tolerance that calibre is held to, and a quick way to remove a bad one.

Your watches don't have to stay drawn. Open any piece in your WatchBox, choose a photo of your own, and it takes the place of the illustration throughout the app.

### 1.0.4 — 2026-11-07

The Bench, rebuilt in 3D. The escapement, gearing, amplitude and beat error, the torque curve and the tourbillon each have their own model now. Slow them down, step through them by hand, turn them with a finger, and watch a live trace beside the motion. The ruby doing the work glows.

Every demo links straight to the matching parts in the full movement.

Plus smoother performance throughout.

### 1.0.3 — 2026-11-03

A refreshed look for our App Store page. Everything inside the app works just as it did in 1.0.2.

### 1.0.2 — 2026-11-01

The app stays fast no matter how long you use it, and taps respond instantly when you come back to it. The Exploded slider in the 3D movement viewer, and every other slider, now grabs wherever you touch it and follows your finger smoothly.

### 1.0.1 — 2026-10-31

Faster everywhere. Changing screens is quick again on recent versions of iOS, where the app's background was being redrawn on every move.

Read aloud. Lessons in The Watch and The Engine can now be read to you by one of three narrators: Seraphina, Michael or James. Turn on Read aloud in any lesson, and choose the voice in Settings, with a preview as you pick. The guided tour can be narrated too.

Smaller fixes and polish throughout.
