Lunette: Watch Box & Diary

Lunette is a private, offline-first app for watch enthusiasts who want to document, understand and enjoy their collection.

CATALOG YOUR COLLECTION
Add watches with photos, ownership and service history, purchase details, materials and documents. Track each watch as owned, sold or wanted.

TRACK WANTED WATCHES
Save listings and searches for watches you want. Follow price changes, view price history and get notified when a listing drops in price or sells.

DAILY WRIST-CHECK JOURNAL
Snap a photo every day you wear a watch. Lunette recognizes which watch is on your wrist and logs it automatically. Build a visual diary of your rotation over weeks, months and years.

TRACK ACCURACY OVER TIME
Run reference-time tests against an NTP-synchronized clock. Save accuracy entries, track drift in seconds per day and see which watches run fast, slow or COSC-tight.

USE YOUR IPHONE AS A TIMEGRAPHER
Measure rate, amplitude and beat error using your iPhone microphone. Record sessions across different watch positions and keep the results alongside each watch. The first 10 sessions are free for everyone.

KEEP DOCUMENTS ORGANIZED
Attach documents to watches, service records and accuracy readings. View them directly in Lunette whenever you need them.

TOOLS, STATS & PDF REPORTS
Find measuring tools, collection statistics and exports in the dedicated Tools tab. Create richer PDF reports with documents, ownership history and timegrapher sessions. Collection exports give every watch its own cover page.

SHARE YOUR ROTATION
Generate beautiful Instagram Stories showing your weekly rotation or watch of the day. Smart cropping keeps the dial front and center.

FULLY PRIVATE & OFFLINE-FIRST
No accounts. No sign-up. No cloud dependency. Your collection data stays on your device. Back up and restore through iCloud whenever you want, on your terms.

ONE-TIME UPGRADES, NO SUBSCRIPTIONS
The free version supports up to 5 watches, 3 photos or documents per watch, 1 journal entry per day and 3 reference-time accuracy tests per watch.

Lunette Pro removes collection, journal and accuracy limits. It also unlocks advanced wishlist tracking, news notifications, premium Story backgrounds and PDF exports.

Timegrapher Pro is an optional, separate one-time purchase that unlocks unlimited acoustic timegrapher sessions.

No subscriptions, ever.
