DuckDuckGo is fantastic on mobile (iPhone). It feels way faster than Google for me — part of that is not getting the "Can I use your location?" pop-ups which then trigger a re-search.

Plus there's no AMP junk in the results! And links are real links — when you copy them you get the URL, not some huge tracking string.

Occasionally I've felt like I'm not getting good results so have gone to Google to repeat the search. There hasn't yet been a case where that's helped, so I've stopped doing it.
