App is perfectly converts equations to LaTeX, MathML, or image format

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...

I have been using MathKey Keyboard app on my iPad Pro to insert math equations when I am using the PDF Expert App.In PDF Expert I would click on the insert "text" button which would bring up the iPad's default keyboard.Next I switch over to MathKey App's KeyboardSelect the "Image" insert option Hand write a math equation and click "copy"Usually at this point it would bring up prompts "Converting" then "Generating" and then display an image of the equation i had written in the bottom right hand corner, which I could copy or drag and drop into PDF Expert.However, recently after clicking "Copy" it will give me the "Converting" then "Generating" prompts and then tell me "Check Your Internet Connection"I have tried multiple different troubleshooting attempts, checking internet connection, making sure App keyboard has Full Access, deleted the App and reinstalled it. I finally downloaded MathKey App on a second iPad connected to the same network and used it exactly as described above and it worked.Could someone please help me solve this issue. I have emailed the App developers but haven't gotten a responce. I had been using this App successfully for several months and cant figure out what has changed so that it doesnt work any more on my iPad, but works on a different iPad.Appreciate any help! Thank You!Prior to this issue would give 5 star review. If you could help me solve this issue I would be happy to change my review :)

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.If you need more details, please email me at contact@mathkey-app.comBest,Nicolas
