About

TimepieceSlate is a private, offline watch-collection ledger for iPhone and iPad. Keep catalog details, wear periods, servicing, and manual accuracy observations dependable without an account, subscription, advertising, analytics, tracking, cloud dependency, or required internet connection. • Catalog watches with brand, model, reference, serial number, movement, calibre, dimensions, acquisition details, status, notes, and optional local photos • Record wear periods and occasions while preventing overlapping entries for the same watch • Keep service type, provider, original-currency cost, receipt, notes, and optional review date • Measure accuracy manually against a reference clock; no microphone or automatic detection is used • Correct, void, or restore facts through an append-only audit history that preserves the original entry • Review factual 7-, 30-, 90-day, or all-time summaries without valuation, authenticity, maintenance, or accuracy advice • Export readable text or RFC 4180 CSV and create checksum-verified backups with preview, merge, replace, rollback, and recovery Your catalog, serial numbers, photos, receipts, history, and backups stay on your device unless you explicitly export them. Optional feedback sends only the message, contact email, diagnostics, and screenshots you choose—not your watch ledger.
