Speedtest by Ookla 4+

I’ve used your speed test app on various devices since you launched it. I do use it to challenge my service provider whenever they decide to steal some bandwidth that they think I won’t miss. This happens on a fairly regular basis. My router reports the capacity of the connection and I know my speeds are usually within 10% of that. Every now and again they try it on and bring the speed down 20% or more. I know this is the case no matter how much they deny it. The speed hits a very specific ceiling and maintains it throughout your app’s check. Thanks for a very useful tool. I have noticed rather a long delay in connecting to your various servers and wondered if that was a problem with my provider or are you having contention issues? It can take up to 20 seconds to start the test on occasion. Once it starts the test shows Nice short pings and consistent speeds but the delay is bugging me??

Having used the app for many years, in the past few weeks I've noticed strange behaviour when using it to test Wi-fi speeds.
Where previously speed readings were stable and consistent, now I find low and fluctuating download speeds on Wi-fi. For example, where I used to get a stable reading of say 400mbs download, now most of the time I get reading as low as 24mbs, or readings that fluctuate from 150 down to as low as 4 mbs during a single test. Occasionally, I can get a stable reading of 400mbs. This happens on an iPhone X with iOS 14.0.2 and Speedtest 4.2.7 and an iPad Pro 12.9" 3rd gen and an iPhone XR with the same software. However, when I test with an older iPad mini 4 with iOS 12.1 and Speedtest 4.2.4, or an original iPhone SE iOS 12.4.1 and Speedtest 4.0.2, I get stable readings of high downloads, 250mbs for the iPad mini 4 and 90 mbs for the iPhone SE.
I have also tested with an iPad mini 5 with iOS 14 and Speedtest 4.2.7 and get the same fluctuating often very low download speed.
Testing using a direct LAN connection on the same network gives high and stable speeds using an Apple MacBook. Is there a problem with 4.2.7 and ios14?

Happy to recommend this app to anyone, however I wouldn’t recommend 3 as your main internet provider. With internet speeds of 0.07 mb/s and under (yet they claim speeds of 75mb/s) no wonder my internet crashes all the time whenever I use it. I’ve used this app and quoted internet speeds to my internet phone provider numerous times, in a bid they do something about it, each time they tell me they’re end sees speeds of at least 35mb/s and over they’re end, and do absolutely nothing about it, yet I never see that on my side. Despite catching them out, the problem still isn’t fixed. So apart from being a great app for catching out scammer internet providers, it’s a shame those said internet providers refuse to listen. Highly recommend this app, but please do not use 3 as your internet provider.
