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

Why do I need to use the remote keyboard on another computer? Couldn’t I access the information from the browser on my IPad? I was looking for an app that will allow me to write LaTex or MathML on my IPad without the need of using another device. So, in this sense, it defeats the purpose for which I purchased the app in the first place.

Is there a way to use the functions without having to connect to the remote keyboard?

Developer Response ,

Actually Remote Keyboard isn’t the main feature of MathKey.

The main feature is the keyboard itself. As shown on the screenshots, you can write equations anywhere you can write text.

To enable the keyboard, open the app, tap Guide and follow the instructions.

If you need more help, please email me at

If your issue has been solved, please update your review.

Thank you for using MathKey.

Best regards
