Network Multimeter is an iPhone app that lets you move around your house, coffee shop, or any wifi location and determine where the best network speed is available--just like you'd use an analog multimeter to determine which batteries in your drawer have the most power left.
Unlike most network speed test apps this one is designed to give you a continuous and instant indication of the quality of the wireless network right where you're standing. Ever wonder why you get better wifi some places than others? This app is here to help.
It's also a quick and easy tool for comparing one access point speed to another, such as when presented with multiple options at a hotel, or just a quick way of verifying that you have sufficient speed for things like video conferencing or streaming video.
Network Multimeter can either time the download speed of a file from the internet or use "ping", a standard protocol for testing the response speed of an address over a network.
Limitations: Note that Network Multimeter is using actual download speeds and ping times to determine the quality of the wifi network and as such the output is not necessarily related to signal strength but rather reflects the real-world results of your overall network connection.
Supported Devices: Version 3 of Network Multimeter was designed for the iPhone and iOS 8. iPads with iOS 8 or higher are also supported. Older versions of Network Multimeter support iOS 5 and higher.
Updated so that even on the fastest connections the download test will continue for the full duration, up to 5 minutes.
