Chrono Vault

Log what’s on your wrist, track rotation and wear, and keep your vault organized—offline-first, with optional biometrics to reveal serials.

Chrono Vault is a luxury watch collection companion built for daily use: log what you wear, understand your rotation, and keep your vault details organized—even when you’re offline.

Wear journal Switch watches with minimal friction. Confirm when you’re still wearing yesterday’s piece, backfill missed days, and edit history when plans change. Optional flows handle same-day changes the way you actually wear watches.

Your vault Add watches with photos, specs, straps, complications, and condition. Archive pieces you’ve moved on from, or soft-remove them while keeping history for insights.

Privacy-minded serials All information is stored locally. Serial numbers can be stored encrypted on device. Turn on Face ID (or Touch ID) to reveal them when needed.

Insights See rotation mix, 30-day wear frequency, and which watches haven’t been on your wrist lately—with thresholds you control.

Moon phase reference A built-in moon reference helps you line up complications and calendar quirks—handy when you’re setting or checking a watch.

Make it yours Choose themes, set a home timezone reference while traveling, and use gentle reminders so logging stays a habit.

Optional connections Sign in to Google for a one-time import from Sheets if you’re migrating from a spreadsheet. Cloud features depend on your build configuration; core journaling and vault features work without an account.

Your collection stays on your phone unless you explicitly use optional import or cloud-related features.
