Behind this innocent looking Unit Converter, there is hidden and secure password protected vault for your photos while using an album interface very similar to your Picture Hub. This is the best app on the marketplace in terms of simplicity, and balance of speed and security. Security: Unlike other similar apps with bells and whistles, we properly put security and privacy first: - Encryption: Other apps store photos as they are behind a password screen. We automatically do full encryption making it practically impossible to hack your photos. - Hidden: other apps offer a decoy password or multiple accounts. This complicates album management and does not solve the problem of hiding you data. We hide the real app behind a fully functional Unit Converter. - No network access: Your data is stored only on the phone. Paid version does not access the network in any way and uses only Media library capability. - Panic Lock on every screen which takes you back to the Unit Converter. - Double lock system one numeric and one alphanumeric for those who are paranoid. Album (or Folder) Management: - Nested Albums - Multi Import Album/Picture from your Picture Hub - Multi Export to Saved Images of your Picture Hub - Multi Album/Picture Delete and Move - Album names are optional - Fast and responsive navigation - Lock/Hide i.e. (Encrypt/Decrypt) root albums Image Gallery Viewer: - Flick to navigate photos - Fastest Pinch to Zoom - Slideshow Typical uses: - Safety: Keep your sensitive photos safe from your children. - Privacy: like when faced with someone asking to borrow your phone. - Secrecy: Keep a stash of your top secret photos. - Convenience: Keep a scanned copy of your classified documents. Support: Use the faq and links inside the app for support, version history, review and suggestions.
