Wolframalpha can’t understand

I though it could be a perfect companion with Wolframalpha, but both the Latex and MathML interpretation are not compatible with it.

Please improve this.

Developer Response ,

Have you tried to enable the option « Remove spaces » ? WolframAlpha LaTeX interpretation is very strict and removing spaces seems to improve compatibility.

If you’re issue is persisting, please email me at with some examples of equations that can’t be interpreted by WolframAlpha.

Best regards

Awesome app!

This app works great! It can save me so much time, why type when you can do this?!

I just hope they add the ability to view and save the code on the iPad so I can just paste into LaTeX later.

Works well.

It’s able to convert my rather terrible handwriting to Latex, can’t complain.
