SecurePass iOS/Android Password Manager

I want to turn my SecurePass idea into a polished mobile application that runs seamlessly on both iOS and Android. At its heart, SecurePass is a fully fledged password-management tool, so every screen and workflow should make it easy for users to create, store, and retrieve strong credentials without ever feeling overwhelmed.

Key functionality I need built in from day one includes:
• Biometric authentication (Face ID, Touch ID, and Android equivalents) so users can unlock their vault instantly without typing a master password each time.
• A strong, customisable password generator that suggests unique phrases or complex strings on demand.
• Secure, encrypted password storage that never leaves the device unprotected—think zero-knowledge architecture with industry-standard cryptography.

The finished apps must pass review in both the App Store and Google Play and come with clear documentation that lets me maintain or expand the codebase later. If you prefer Flutter, React Native, Swift + Kotlin, or another modern stack, I’m open, provided the user experience remains consistent across platforms and the security layer is rock-solid.

Please outline your proposed tech stack, any relevant security libraries you rely on, and a rough timeline for initial MVP and final release.
