No guide no instructions No guidee cant know how ita works wolfram is better in that

A Google User

Ads need phone info? So it seems like the ads need my phone state and identity. Somethings wrong with that so I'm uninstalling. I'd happily buy an ad free version.

A Google User

This thing is really cool! I hate having to do hard integrals so this thing is a life saver. Indefinite ints would be a cool addition.

A Google User

Pretty cool! Implement it for indefinite integrals as well and I'll throw another star your way.
