DETAILED STATISTICS & WRIST TIME
Don't just store your watches—analyze your collecting habits with powerful charts and visual indicators:
Global Dashboard: Instantly visualize your collection's key data (total number of pieces, invested value, distribution by style, movement type, or brand).
Per-Watch Stats: Access analytical breakdowns for each timepiece to track its precise "Wrist Time," wear rate over the month or year, and the exact number of days spent on your wrist.
Smart Morning Routine: Log your watch of the day with a single tap to fuel your stats. Pair the app with physical NFC tags or QR codes stuck on your watch boxes or rolls: just bring your iPhone close to instantly put your watch on your wrist!
ADVANCED SEARCH & MULTI-CRITERIA FILTERING
Find any piece or accessory in a flash thanks to an ultra-high-performance filtering system:
The Strap "Super Filter": In your Strap Garage, instantly cross-reference criteria (material, color, exact lug width) to find the perfect combo for your watch of the day.
Smart Text Search: Instantly filter your inventories by brand, model, caliber, or specific features.
ADVANCED COLLECTION MANAGEMENT
Comprehensive Tech Sheet: Record every single detail of your pieces (reference, serial number, lug-to-lug measurements, thickness, power reserve, water resistance, crystal type).
Automatic Maintenance Alerts: Log your history of service, mechanical overhauls, or cosmetic touch-ups. Horolens immediately alerts you via notification as soon as the recommended service interval is exceeded.
INTEGRATED CHRONOCOMPARATOR (TIMEGRAPHER PRO)
Analyze the health of your mechanical movements directly with your iPhone. Thanks to our exclusive DSP engine, use the internal microphone or an external Piezo/USB sensor to measure in real time:
The Drift: Daily rate (in seconds per day).
The Amplitude: Exact oscillation degrees of the balance wheel.
The Beat Error: A clustering filtering algorithm measuring the asymmetry of the alternations (in milliseconds).
PDF EXPORTS & SECURITY
ID Sheet: Export a sleek, comprehensive dossier of your watch for insurance purposes if needed.
Bill of Sale: Instantly generate a compliant PDF sales certificate with a pre-filled seller identity and signature when parting with a piece.
Free download (manage up to 3 watches). Unlock Horolens PRO via a one-time in-app purchase for unlimited access, the 35,000+ reference catalog, the advanced chronocomparator, full filters and statistics, unlimited PDF exports, and to support independent development.
