Tools that work for real.
Vaultools is not a fake shell. The toolkit is the front door, and every tool is designed to be useful on its own — so the app earns a normal place on your home screen.
Currency converter
Live exchange rates between major currencies, with the date of the latest update shown.
Unit converter
Length, weight, temperature, and timezone — switch units quickly without leaving the app.
Size converter
Women, Men, Shoes W, and Shoes M sizing across regional systems for clothes and shoes.
The hidden vault
What stays inside, stays inside.
Under the toolkit, Vaultools keeps a private space for photos, videos, and files organized in albums and folders you control.
Confidential documents, personal records, scans, and projects — all out of the camera roll and out of the regular files app.
Photo & video albums
File folders
Slideshow viewer
On-device storage
One app, two faces.
The same icon opens the toolkit anyone can see. The same icon, with the right gesture, opens the vault only you know about.
Inside the vault
Albums and folders, your way.
Group sensitive media into albums, keep files in folders, and browse them with a viewer designed for private review.
- Separate albums for photos and videos.
- Folders for documents and important files.
- Built-in slideshow for quick review without exporting.
- Files stay on the device — no cloud sync by default.
For anything that should not be one tap away.
Built for the people who share their phone, hand it to children, or just don't want every album visible in the photo gallery.
Personal records
ID copies, contracts, receipts, and PDFs that don't belong in the regular files app.
Private media
Photos and videos kept out of the camera roll and out of cloud backups by default.
Shared phones
When someone borrows the phone, all they see is a calculator and a few useful converters.
A toolkit on the outside. A vault on the inside.
Vaultools keeps the everyday tools you actually use, and a private space for everything else — on the same icon, on the same phone.
