amazing LaTeX renderer
The ability of Mathkey to render LaTeX expressions is excellent. I use it exclusively to generate complicated expressions on my iPad, with delivery to my Mac via the Mathkey webpage (i don’t typeset on iOS devices). In this mode, full keyboard access is not needed, in fact no keyboard is needed at all. I now agree with the author that full keyboard access *is* safe, as long as you don't typeset your credit card info in LaTeX, it has no access to what you type with the other keyboards (of course, since the rendering is done server side, the information is disclosed no matter what, but my research is not classified).
Developer Response ,
I think you already read my reply in the other review about Full Access. You know how Apple cares about privacy. Do you think that they would let developers access what you type or have typed with other Keyboards ?
In other words:
The only interaction MathKey can do with iOS is to say : « insert this text at the cursor position » (it can even move the cursor) and « delete the last character ». MathKey is totally blind : it can’t see what it has deleted or what is around it has inserted.
So if you don’t use MathKey to write sensitive information, we absolutely have zero way to access it.
We used to have an offline conversion engine in the first version but many users reported that it kept crashing. Indeed, MyScript’s engine uses more RAM than iOS allocates to Keyboards so it just kills the keyboard. It’s a shame because newest devices are fully capable of providing more RAM to Keyboards... So we quickly moved to online conversion because it was the most reliable solution. And in order to let MathKey access the conversion server, it need to be granted the Full Access ability. Believe me, if we had the choice, MathKey wouldn’t ask for this option.
I really understand your concerns but you really should trust this app. That is just the way Keyboards work : the only things with they can read is what you type with it.
If you have some basis in development, I invite you to read the third-party Keyboards API docs: there isn’t any method allowing you to read the document.

Makes equation writing so much more accessible
I have been using Latex for a long time, but lately only sporadically. That means I have to look things up a lot to find the proper commands. This app makes writing equations so much easier. No more wasting time to find what to type in Latex to generate the proper result.
The app’s writing recognition is very good, but not infallible. However, since the app’s keyboard allows me to individually delete parts of the input and redraw them in a more readable manner, this is not a big issue in practice.
The part that was a real nice surprise was the app’s ability to recognize multi line equations. Most others I have tried turn that into a fraction of some sort.
The remote keyboard connection is a welcome addition. While I think I could manage with copy and paste between iPad and Mac, having the ability to draw equations in full screen mode on my iPad and have the results appear on the desktop makes it really easy to work with, especially since that’s where I usually need my equations.
A really great app that makes good use of the iPad combined with the pencil

Thank you for your amazing review ! I’m glad that MathKey helps you be more productive.
Feel free to email me at firstname.lastname@example.org if you have any suggestions.
Not good for any equations that actually require LaTex
With a few tries it can get simple expressions, but it is near impossible to do something like a definite triple integral. I could not get it to work for a simple center of mass triple integral. What really bothers me too is that when it doesn’t work it asks me to check my internet, even though I have functioning wifi and if I immediately after getting that message write something simple (like “x”) it works. The app simply cannot convert most equations I need it too, it is not the fault of my wifi. The equations it can convert you may as well do in google docs for free. I regret buying this app. As cool and useful as the app seems, I have certainly wasted more time trying to get it to recognize equations than I would have if I wrote them anywhere else. Thanks for reading and please consider my warning.

I am sorry to read that MathKey does not work as well with you as it does with others users.
I would recommend you to switch the recognition engine to one that works better for your handwriting.
To do so, go to https://mathkey-app.com/user/engine and click on Sign in with Apple ID. This is totally safe and it will allow you to switch the recognition engine for all devices connected to your Apple ID.
Please let me know if it works better by emailing me at email@example.com.
