I would argue the calculator is still a fail. If I searched or Tweetbot, the top hit should obviously be Tweetbot, but I would argue that the other results should be other Twitter clients. A calculator simply isn't. Even worse, the 3rd result is for a different tapped named "Tweetbot" When you scan through the results, Calcbot is really the odd one out. Now, if I had searched for Tapbot (the maker of Tweetbot), then sure, Calcbot makes sense.

Running a search for "tapbots" indeed gives me Tweetbot and Calcbot in the 1 and 2 slots, but the rest of the results are shit. Some competing apps, and of course "Resturant Fan Logo Quiz" in slot 4 for some reason. (It's in slot 5 for "tweetbot".)

These results are still, not very good beyond position 1. Perhaps Apple should simply start thresholding results instead of inciting on an infinite scroll of results.
