Works Well when it works, but "Error: Check your internet connection"

Why this app needs internet, I do not know. Maybe because it was ported from a mobile version, the devices were not powerful enough to run the conversion. It works sometimes, and it works well, it's very helpful. However the large majority of the time I get this error that renders the app useless. Also, it would be nice if they implemented inputting an image. Currently, only iPads have the ability to emulate a mouse on Macs, but I have a device that I could create .pngs or .jpegs of my drawn formulas.

The two star is for the inconsistancy, when it works I really like it. Hopefully this problem can be ironed out in a software update.

Mostly a waste of $

I purchased this app to make note-taking for my statistics class easier, but it wouldn't fully convert the first equation I tried. I attempted it at least 3-4 times, but it would only convert 1 out of the 2 p-hats in the equation.
