Calculator+ review
A focused Android vault with local encryption, private albums, and optional cloud backup.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Calculator+ is an Android photo and video vault from Green Water that presents itself as a functional calculator. A passcode entered through the calculator interface opens the private vault, where users can import photos and videos, arrange them in private albums and folders, and manage a separate video vault. It is aimed at Android users who want discreet storage for personal media, particularly those who value a calculator disguise alongside ordinary vault functions.
Its strongest angle is the combination of privacy controls and media organization. Calculator+ uses encrypted local storage and supports direct photo capture into the vault, so users can add new images without first placing them in the standard gallery. Fingerprint unlocking provides an additional access method as a premium feature. Export, move, and share tools allow decrypted files to leave the vault when needed, while private albums and folders provide a clearer structure than a single concealed media list.
Calculator+ also extends beyond a device-only vault through optional encrypted cloud backup and multi-device synchronization. That makes it more suitable for users who want continuity across Android devices, although the broader feature set depends on using the optional cloud service. The main boundary is platform coverage: Android users get the full product direction, while people seeking an iPhone option or a cross-platform vault should choose an alternative. It is a focused fit for discreet Android photo and video storage rather than a general-purpose gallery replacement.
