The response is quick and the reporting is reliable, free from all the overhead of the browser and any cache etc that can and would be in the way. This app is well put together and the options it gives you are just what is needed with no extra fluff. I always found that depending on your web browser you could get different results and its far better to have a local run application to cut out as much of noise from applications to get a truer picture of what your results are. I retired from IBM in 2008 with 30 years of working with computers/networks Speedtest has been my go to network test for as long as I can remember. I have been a longtime Ookla Speedtest user for many moons….

How do software engineers let stuff out the door like this? I’m still rating this a 3 because I like this app so much, but these bugs need to be addressed FAST. If your speed is 95, the needle point back at like 0 or 5. So if your speed is being measured as 30,the needle points to the exact other side of th dial and says soething like 400. But the new “added feature” of this current release is that the indicater needle on the dial now points in the 180 degree opposite direction of the measurement. Now it is set to 500 and there’s no way to change it. You used ot be abe to calibrate the dial so that….for example….if your connections are generally in the range of 0-100 mbps, you could set the top end of the dial to 100. The most recentupdate has some obvious bugs that I can t beleive they did not catch before releasingthis to the public. I love this app and have used it for a longtime. Best speed testing app out there and also the prettiest interface IMHO. I appreciate their super-fast attention to this. The major bugs disussed below were fixed by the developer only a day after they were reported.
