Gold standard
This one is the gold standard. The best. The only one. Even Time Warner uses it as the engine for the speed test on their website.
Having it as an app is better as it saves the results as a list of all the days, times, and Types of connections.
The only suggestions I would make would be to be able to add a note to each record. For instance, I would want to add a note as to where in my apartment I did the test.
Also I would want to export all the results as a tabbed delimited file to merge in a spreadsheet.
I can currently "share" each test as an email. But its not all of them at once.
Perhaps Ookla would make this a paid upgrade version.
These suggestions are luxury features. They dont take away from my 5 stars.
