MathKey - LaTeX Converter

My goal was to find something that could transform handwritten mathematical equations into text/images. This app does, in fact, accomplish this. However, when the variable involves multiple subscripts, the app fails to recognize this and places a single value instead. Seeing as I was using the geodesic equation to test the limits, I can understand the issue and would not have any qualms about it if the app allowed me the chance to correct the situation. Since I can’t see what the text value converts to, it’s difficult to know if something has to be fixed. Furthermore, when converting it into an image, the written equation vanishes, leaving you to rewrite it blindly which ends up resulting in the same problems. This means I have to edit the image on a separate app which defeats the purpose in my opinion. There also seems to be certain elements it has trouble with converting to image, such as angstrom. A solution would be to have the written equation remain after copying it so that you can adjust accordingly. This would also help the issue of not being able to see what the text result would produce (unless you are fluent in LaTex or MathML). That being said, I find myself reverting back to using word on a computer instead of being able to use my iPad which makes this a waste of $8. If there was also an option of a math keyboard with the ability to type mathematical symbols (like Greek letters, subscripts, etc…) I would feel the price was worth it. Hopefully my $8 will assist in getting this app up to the standards I expected for future use.

This app should be a little clearer in informing potential users upfront that it works by adding a new keyboard to iOS or iPadOS. It’s math recognition engine is *very* good, and it’s quite handy. Why only four stars, then? I feel that it’s missing one key feature: a built-in scatchpad or viewer of some sort. Currently, you have to use a third-party LaTeX app or notepad app (the built-in Notes app is … okay for this purpose — it doesn’t directly support LaTeX, so it’s little help there, but it can work with the images created). If the developers would add a scratchpad feature that could render the LaTeX *and* accept the images, also, that would ideal and the app would earn five stars from me!

I like the concept of this keyboard, and as far as handwriting recognition with the Apple pencil goes, it is pretty accurate, though not as accurate as MyScript Nebo, which is a standalone app. MyScript Nebo will recognize my handwriting even if I write sloppy, whereas with this app, I have to make sure I’m writing slower and more neatly, which makes it less efficient. Most importantly, the main reason I bought this keyboard was to input MULTI-line expressions in the form of images, like you can in MyScript Nebo, into Word and PowerPoint documents. As far as I can tell, there is no way to do this with this keyboard. Anytime I attempt to write more than one line it bunches the expression together into one long line with multiple equal signs. Very irritating. I have to input each line separately, which is time consuming and defeats the purpose of me getting this app to begin with. If the developer can add this feature, that would be great. Looks like I have to go back to using MyScript Nebo in multitasking mode in the meantime...
