What is it? An app for testing the data connection speed of your phone.
How is it of use to journalists?
If you are out in the field, perhaps on a 3G connection, and want to stream live video or transfer large files, a speed test app is really valuable.
This one comes recommended by BBC 5 Live's Nick Garnett, who is well known for iPhone reporting.
Garnett mentioned the need for a speed test app at the recent BBC News Festival, an internal BBC training day held last month. He highlighted the need to find a reliable, fast connection before attempting to livestream video or go live to a radio studio using an app such as Luci Live.
There are a number of other speed test apps available. This one is made by a company called Ookla.
