I think this is a much more accurate characterization, especially in AutoTempest's case. Their experience on mobile has always been slow and glitchy. I'm not sure what makes their web "app" so heavy, but it's very noticeable.
Can you share details? Or feel free to email me directly, nathan at autotempest. I'd like to learn more about your device, browser, and search criteria so we can try and reproduce what you described.
