Deriv is easy to use and very fast because it uses its own built-in engine for differentiating functions and hence doesn't rely on slow third-party services. The most notable features of this app are:
- Evaluation: after computing a derivative, you can quickly evaluate it by providing values for variables. It's very easy and convenient.
- Persistence: everything you do is stored in a database on your device, this way you can easily recover all your previous computations when you need them again.
- Beauty & Clarity: all mathematical expressions are rendered with KaTeX and look just awesome. Also, Deriv's differentiation engine tries its best to make the resulting functions as clear and readable as possible.

Small improvements in the underlying differentiation library.
