What’s New

Version 1.3.3

This update fixes the use of MathKey with a Smart Keyboard or Bluetooth keyboard. If MathKey doesn't appear with your physical keyboard, long press the arrow at the right if there is any or press the Eject key if you have one.

● Version 1.3 ●
- Supports 2nd generation Apple Pencil double-tap feature : you can easily switch between the pen and the eraser or display the color picker.
- Supports new iPad Pro 11 inch display.
- Pencil Lock : automatically disable finger input while writing with an Apple Pencil.
- MathML support : choose between LaTeX and MathML in the app's settings.
- Better support of WolframAlpha® with an option removing spaces.
- New installation tutorial.

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).

Hi,
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.

Missing a crucial feature...

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...

Edit : multi-line equations are now properly rendered. I would love if you could update your review ! Enjoy using MathKey.

Hi,
Thank you for your review.
I am currently working on a fix for multi-line equation images. No update will be required and it should work by the end of the week.

As of recognition being better on Nebo, I will have to run some tests and may be do some adjustments. It should be as efficient as Nebo as it relies on the same engine.

If you have other suggestions, feel free to contact me at contact@mathkey-app.com

Best regards,

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
