TetherFi works by creating a Wi-Fi Direct legacy group and an HTTP proxy server. Other devices can connect to the broadcasted Wi-Fi network, and connect to the Internet by setting the proxy server settings to the server created by TetherFi. You do not need a Hotspot data plan to use TetherFi, but the app works best with "unlimited" data plans.
- You want to share your Android's Wi-Fi or Cellular Data
- You have an Unlimited Data and a Hotspot plan from your Carrier, but Hotspot has a data cap
- You have an Unlimited Data and a Hotspot plan from your Carrier, but Hotspot has throttling
- You do not have a mobile Hotspot plan
- You wish to create a LAN between devices
- Your home router has reached the device connection limit
TetherFi uses a Foreground Service to create a long-running Wi-Fi Direct Network that other devices can connect to. Connected devices can exchange network data between each other. The user is in full control of this Foreground Service and can explicitly choose when to turn it on and off.
TetherFi is still a work in progress and not everything will work. For example, using the app to get an open NAT type on consoles is currently not possible. Using TetherFi for certain online apps, chat apps, video apps, and gaming apps is currently not possible. Some services such as email may be unavailable. General "normal" internet browsing should work fine - however, it is dependent on the speed and availability of your Android device's internet connection.
