  I'm with you. Some open source app is all they need. However to answer your question: phone rules in classrooms vary enormously and the dedicated calculator is faster to interface when you're drilling problems in a homework setting I finished highschool in the (gasp) 20th century so the modern classroom is certainly something I've had to learn

  >kids have smartphones, what's the point of a graphing calculator? Many tests will not allow you to use a smartphone. My son couldn't even use the school issued chromebook on his PSAT, he had to get a loaner Windows laptop or use an approved hard calculator.

  Ironically builtin smartphone calculators are really bad, and one of the best ones you can download might be Graph 89 (a TI-89 emulator). Rant/Aside: Smartphones (or at least Android) are just generally really bad at being... smart, especially out of the box. No dictionary? No thesaurus? To say nothing of built-in encyclopedia (e.g. Wikipedia). Calculator worse than the $1 scientific ones? It's astounding how obvious it is that they're meant to dumb people down and just sell you crap when you look at the complete absence of basic functionality anyone from 50+ years ago might expect them to have.
