A closer look.






About this app
Made for a clear purpose.
Glyphsieve: Unicode Lab is a focused, fully on-device app. A Unicode inspection and text-security studio for code points, graphemes, normalization, scripts, bidirectional controls, confusables, encodings, and reversible transformations.
KEY FEATURES - Inspect scalars, grapheme clusters, scripts, and categories - Compare NFC, NFD, NFKC, and NFKD transformations - Reveal bidirectional and zero-width control characters - Screen mixed-script and confusable identifiers - Decode UTF-8, UTF-16, escapes, and byte sequences - Complete bundled sample and local comparison workflow - Local PDF report and Apple system share export - Original offline technical reference library
ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core features and bundled content work offline - Work remains on device unless you deliberately share or export it through an Apple system interface
Screening aid only. A visual similarity warning does not prove malicious intent; apply a documented identifier and internationalization policy.
