Kryptos is a privacy-first password manager for iPhone and iPad. Your credentials are encrypted on your device before anything is saved to your own iCloud Drive or Google Drive vault—so you stay in control of where your data lives. WHY KRYPTOS • End-to-end encryption on device with AES-256-GCM and Argon2id key derivation • Unlock quickly with Face ID or Touch ID • Works offline—browse, add, and edit credentials without a connection • No ads, no analytics, and no third-party tracking SDKs STORE EVERYTHING YOU NEED • Logins with usernames, passwords, site URLs, TOTP authenticator secrets, and security questions • Credit and debit cards, bank accounts, Wi‑Fi passwords, SSH/API keys, and passkeys • Secure notes with flexible sections • Custom fields on any credential type FILL PASSWORDS FASTER • Password AutoFill extension for Safari and supported apps • Built-in password generator • TOTP codes for accounts that use authenticator apps STAY AWARE OF RISK • Security dashboard with strength and reuse insights • Breach checks using k-anonymity (only a partial hash is sent—never your full password) SYNC ON YOUR TERMS • Optional encrypted vault sync to iCloud Drive or Google Drive • Your master password never leaves your device; cloud storage holds only an encrypted vault file Designed with accessibility in mind: VoiceOver, Dynamic Type, and WCAG-minded contrast in the Cipher light and dark themes. Kryptos is built native with Swift and SwiftUI for iOS 17 and later.

Verdict
The clearest difference is in-app purchases: Kryptos at none against HTML Viewer Pro's 2. Kryptos also leads on ads (none vs shown) and update cadence (weekly vs every 15 months). HTML Viewer Pro's advantage is iOS requirement (12.0 vs 17.0). On price and device support there is nothing between them.
