About this app

TetherFi uses a Foreground Service to create a long-running Wi-Fi Direct Network for other Connected Devices.


• What

Share your Android device's Internet connection with other devices without needing Root.

You will need at least one Android device with normal access to the Internet, either via Wi-Fi, or a mobile Data plan.

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.

• TetherFi may be for you if:

You want to share your Android's Wi-Fi or Mobile 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

• How

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.

Ratings and reviews

Works perfectly! Full cell network speed, can't ask for more! My current plan includes 3G Hotspot so my phone has Hotspot permissions; this review may be biased. I hope those with AT&T who opted out of Hotspot can confirm if this app works for them. That was my biggest gripe with most other Hotspot apps. Quick update: It's worth noting that Steam and Discord will not work. Steam because of the use of a proxy, Discord... No clue.

Works great. thanks for the W app, using this to finish my school work without using my hotspot data. The only issue I'm having, USB Tethering isn't working for me, I've done the steps that it says, like location, enabling USB Tethering, etc, but it says USB Tethering isn't enabled, but other then that, wifi seems to work well

App works perfect. It's a nice workaround when you're primary source of internet is your mobile, but you don't have a lot of Hotspot data. I connected to my pc, MacBook, and 2 ps5s just to see if it works, and it worked perfectly. Only issue I've come across is the ps5, it won't connect to a NAT that allows me to connect to the playstation network. I'm sure there's a workaround, just haven't gone into in depth troubleshooting. I still had connection though, and it downloaded updates. Great app
