Trace, extrema, inflection points, tangent lines are all readily available with a few taps of your finger. On the downside, there is no simple scientific calculator. It’s also a minor bummer that there’s no 3D in an app that’s 100% focused on graphing, but there’s only one app on this list that has 3D.
