Calculator# review

Calculator# from NewSoftwares.net hides its vault behind something nobody looks at twice: a calculator. The App Store listing says it can hide photos and videos and, optionally, delete them from the Photos app once moved, and that it also stores documents, audio, passwords, notes, contacts and to-dos. Locks include a calculator code, PIN, pattern, password or Face ID. For snoopers it adds a Panic Switch that jumps to another app, a Disguise Mode that shows a fake crash message and a Hack Monitor that logs failed attempts. Backups can go to iCloud, Dropbox, Google Drive or OneDrive, and a forgotten password can be recovered by email. The free version has ads and limits; the full, ad-free version costs $4.99 a year on the US App Store, the cheapest paid tier here. The listing does not say how files are encrypted. We compared documented features and published prices; we did not test each app.
