## What is iPerf 3 Wifi Speed Test?

Online performance tests will tell you how fast your Internet connection is overall, but your service provider's speed is not the only factor: Wifi itself can significantly affect speed, latency and reliability. And with broadband Internet connections getting faster and faster, Wifi usually already is the bottleneck.

This app requires an iPerf 3 server and will help you set it up on your computer. You will then be able to test your Wifi connection in isolation of your Internet connection across your home or office and tell your exactly what bandwidth you can expect in every room. You can then adjust your settings and move access points around or decide to upgrade your equipment until you achieve super solid Wifi.

If you are already familiar with iPerf 3, here is what you can expect from this app:

* tiny: the app only embeds the iPerf library and UI code

* modern: based on the latest open source stable iPerf 3.6 codebase

* stable: we ran extensive tests to assess stability and give you the most accurate performance numbers

* fast: the app has been tested for memory leaks, does all the processing in a background thread and has been analysed with Instruments to make it as fast as we can

* simple: the UI is really simple and maps straight to iPerf command line parameters, and the embedded help section will assist you in getting started and provide advice on how to achieve the best possible Wifi performance

* open source: no surprises, you can look at the source code on GitHub which is what we use to build the app

Tiny app bundle size, simple UI - ideal!

## Frequently asked questions about iPerf 3 Wifi Speed Test

### What does this app do?

This app allows you to test your Wi-Fi connection's speed and performance independently of your internet service. It helps you set up an iPerf 3 server on your computer to measure the actual bandwidth available across your local network.

### How does this app measure Wi-Fi speed?

The app requires you to set up an iPerf 3 server on a computer connected to your network. It then uses this server to conduct tests, measuring the data transfer rate (bandwidth) between your device and the server, effectively isolating Wi-Fi performance.

### Is this app free to use?

Yes, this application is free to use. It does not contain advertisements or in-app purchases, and its source code is available on GitHub.

### What are the benefits of testing Wi-Fi speed with this app?

By testing your Wi-Fi speed in isolation, you can identify if your Wi-Fi network is the bottleneck in your internet performance. This allows you to pinpoint areas with poor signal strength or slow speeds within your home or office and take steps to improve your network, such as adjusting access point placement or upgrading equipment.

### What devices is this app compatible with?

The provided information does not specify exact device compatibility beyond being a mobile application. However, it is designed to work with an iPerf 3 server that can be set up on a computer, implying it's for users who have both a mobile device and a computer on their network.
