How Feem Works

Feem requires no Internet connectivity to link your devices.

About Feem

Feem is an app, that allows you to transfer files from one device, directly to another device, without passing through the Internet.

Think of Feem like Whatsapp/Messenger/Dropbox, but without using your Internet connectivity.

  • Feem is Fast. About twice as fast as Dropbox. And 50 times faster than Bluetooth.
  • Feem is unlimited. File transfer solutions like Dropbox have file transfer limits. Feem has none.
  • Feem is super secure. Feem doesn’t use any servers online. There is no server storing your files for a hacker to hack into.

How are devices identified?

By default, Feem assigns random names to devices. E.g. Sarcastic Lizard.

You can change the name of your device by upgrading to Feem PRO.


For Feem to do its magic, all your devices need to be close together, within the same Wi-Fi network. Technically within the same LAN (subnet).

This means you can’t use Feem to send files to someone in a different city.

That said, you will find Feem extremely useful at home, at school, and at work.

Feem is equally extremely useful in remote or crisis areas without reliable Internet connectivity.

How is Feem different from similar apps?

Here are the 3 major advantages Feem has over similar apps.

  1. Security. Feem encrypts all local file transfers with TLS. The others don’t.
  2. Full-Duplex. Feem operates in full-duplex mode. You can both send and receive files AT THE SAME TIME. Similar apps operate in half-duplex mode; you are limited to either sending or receiving; you cannot send and receive at the same time. This limits productivity, especially in an office environment.
  3. Business Model. Our business model is simple: If you like the app, you’ll pay for it. Similar apps focus on growth only, then later switch to serving you adware and malware.
