File transfer

From Mac to PC, with a simple drag

1
Your devices show up
Open KairOS on both computers, on the same Wi-Fi: they find each other and appear on the radar, with their names.
2
Drag your files
Files or whole folders, dropped with one gesture onto the device you want. No account, no cloud.
3
Check the code
The same 6-digit code shows on both screens: proof it is the right device. You accept.
4
The files arrive
Encrypted, straight from one computer to the other, with live progress and speed. Nothing is overwritten.

Discover file transfer

Your Mac’s health in one colour
Memory freed in one gesture
When the disk fills up, the gorilla comes to tell you

Applications

Uninstall for good

Dragging an app to the Trash leaves files behind. KairOS finds everything that belongs to it: the app, its settings, its caches and its leftovers.

Your apps sorted by size, with their developer
Every related file visible before you delete
One action to remove it all

KairOS · uninstall an app and all its files

Compact menu

A menu that folds away without losing you

One click shrinks the sidebar to its icons. One click on an icon opens the list of its pages, and the gorilla still says hi.

More room for your lists and files
Each icon opens a small menu with the pages of its group
One more click to expand it all again

Hidden folders

Hide your sensitive folders

Make folders invisible and locked. Only you can find them again, right here in KairOS.

Unlock with Touch ID, the same protection as your Mac
Your folders stay in place, invisible in Finder
They are never deleted
