1.3.0

October 16, 2026

What's New in Version 1.3.0 BUFF3R delivers a comprehensive overhaul of data protection, backup automation, peer identity architecture, contact validation, and UX navigation: Autonomous 30-Minute Encrypted Backups • Automated backups now run every 30 minutes, instantly upon any contact change, and on app launch. • Real-time countdown progress ring and instant manual backup button in Settings. • Set a master backup encryption password during onboarding or with our quick upgrade prompt. • Automatic 3-file rotation preserves device storage and privacy. • Full support for iOS Files app ("Files > On My iPhone > Buff3r"). Digital Identity Profile & Encrypted QR v2 • 100% on-device procedural 8x8 pixel avatar generator with custom cyber color palettes. • AES-256 encrypted peer-to-peer QR protocol (v2) protects your contact information from third-party camera scanners. • Direct QR codes for Website, LinkedIn (with outreach analytics), WhatsApp, Email, Telegram, and Signal. • Centered logos and high-contrast full-screen event mode for easy scanning at conferences. Smart Peer Matching & Deduplication • Rescanning existing peers now opens a connection card with live channel diffs—no duplicate contacts. • 1-Tap Channel Sync updates your peer's latest details without overwriting your private notes or history. New "Important" Contact Status • Tag high-priority leads with a single tap from the scan modal, Bunker card swipe, or contact details. • Filter VIP contacts directly from the Bunker list and follow-up analytics dashboard. Strict Data Validation & Integrations • Added Signal and Telegram support with smart "Paste from App" cleanup. • RFC-standard validation prevents typos and invalid formatting across emails, phone numbers, and profile URLs. UI Polish & Performance Fixes • Unsaved changes guard in Settings prevents accidental loss of edits when switching tabs. • Seamless navigation flow between Settings and Digital Profile. • Smoother drag-and-scroll responsiveness in modals and follow-up messages. • Restored tab navigation icons and overall native performance improvements.
