Frequently Asked Questions

Is Feem v3 compatible with Feem v4 ?

Feem v4 only detects other devices with Feem v4. Feem v3 only detects devices with Feem v3.

Can I use Feem without an Internet connection?

Feem doesn't use the Internet to transfer files. All file transfers are done over your local Wi-Fi network. In fact, you don't even need a server !
This makes file transfers over Feem faster than using the Internet. Feem is the perfect local sharing utility for schools, homes, offices, and any other institution with an internal Wi-Fi network.
No Wi-Fi, No Problem. Create a portable wifi hotspot on your device, and share your connection with other devices.

My devices do not detect each other !

The number one reason Feem doesn't detect other devices is because the devices are not in the same local/Wi-Fi network.
Follow the checklist below:
Have you installed Feem v4 on all your devices? You need at least two devices running Feem v4 in your local network.
Note that Feem v3 is not compatible with Feem v4. You need to install Feem v4 on all of your devices. Feem v3 and Feem v4 both have different logos.
Have you checked that all your Feem devices are on the same Wi-Fi network ?.
Have you checked your Firewall settings for Feem ? If your firewall is on, ensure that Feem is allowed by your firewall. For Windows 7 users, ensure that Feem is allowed in your firewall settings in both Public and Home networks.
Can you make sure that your router/firewall doesn't block UDP broadcasts from Feem? If it does, you'll need to ensure your router/firewall allows traffic from UDP port 45001.
Can you make sure that your router/firewall doesn't block TCP traffic from Feem ? If it does, you'll need to ensure your router/firewall allows traffic from TCP port 45001.

Is the privacy of my files guaranteed ?

Yes. To a very great extend.
File transfers over Feem are directly between devices. Your files are not transmitted over the Internet. This means your ISP cannot spy on your file transfers.
File transfers over Feem are not stored on any server. This means we cannot access your files.
File transfers over Feem are "PUSH", and not "PULL". This means no one can access your files using Feem unless you explicitly send those files.
If you buy the business license of Feem, you'll get a more robust version of Feem with extra privacy and security options.

What is Wi-Fi Direct on Feem and how do I use it?

Wi-Fi Direct on Feem creates a personal Wi-Fi hotspot for you, without a router.
Transfer speeds with our Wi-Fi Direct feature are even faster than using your Wi-Fi router, since file transfers go from your device, directly to the other device, without passing through an intermediary router.

If your device supports Wi-Fi direct, you will see the Wi-Fi Direct option inside Feem. Activate Wi-Fi Direct Mode by clicking on the Wi-Fi Direct option in Feem.
Only one of of your devices needs to have Wi-Fi Direct enabled.
Upon activation, a random Wi-Fi hotspot is created with the name of the device, with a random password.
Your other devices are expected to join this new Wi-Fi hotspot, which will show up in their list of Wi-Fi hotspots.

Transfer Speeds Are Slower Than XYZ

If your transfer speeds are slow, you are probably not using our Wi-Fi Direct feature. Read about our Wi-Fi Direct feature above.

My file transfers are too slow !

If your Feem displays speeds below 500 KB/sec, your file transfers are too slow. Follow the checklist below:
Your device might be equiped with a weak Wi-Fi antenna. This is especially true for android phones. The farther away your device is from the router, the weaker the Wi-Fi signal on your device. Put your devices as close as possible to your Wi-Fi router for faster file transfer speeds.
Also, you might be using Feem to transfer files to multiple devices simultaneously, which might slow down individual file transfer speeds.
Finally, note that the heavier the files you wish to transfer, the longer your file transfers will take.

How is Feem different from other 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.

How do I launch Feem v4 on Linux.

Feem v4 on Linux requires a 64bit Linux Operating System. The installer for Feem is distributed as a .AppImage
Feem v4 for Linux also requires libgstreamer:
$ sudo apt-get install libgstreamer-plugins-base0.10-0
Note that you don't need root to run Feem.
To run Feem v4 on Linux, give executable rights to the Feem v4 AppImage you downloaded. You can either right click on the file and give it executable permissions, or chmod u+x Feem.AppImage
Every time you wish to run Feem, simply double click on the AppImage file.

Note that gstreamer-0.1.0 has been deprecated in Ubuntu 16.10.
Find below an alternative way to get gstreamer-0.1.0 on your box

# download with wget

$ wget
$ wget

# Now install with dpkg

$ sudo dpkg -i libgstreamer0.10-0_0.10.36-1.5_amd64.deb
$ sudo dpkg -i libgstreamer-plugins-base0.10-0_0.10.36-2_amd64.deb

$ sudo apt-mark hold libgstreamer-plugins-base0.10-0
$ sudo apt-mark hold libgstreamer0.10
