EQ Editor is an app for iPad that lets you create math equations and export them in PDF, MathML or HTML formats. The iTunes page for the app is here. The current version is 3.0 or later and it requires iOS 7. The official website: http://www.eqeditor.com/ has more information on the current version. Previous versions (which used iOS 6.0 or earlier) have been retired and are no longer available for download.

There is also freeware EQ Reader app that let’s you view saved MathML and TeX files and export image versions of them. The iTunes page for that is here.

You can contact the app writer through email: support–at–eqeditor–dot–com or by commenting on this site.


Retired apps

There used to be a universal version of the app called EQ Editor Lite as well as two other apps, EQ Notebook and EQ Writer. These are currently retired, though some of their features may come back in some form in the future.

    Hi,

    I enjoy using your app however am unsure on how to load a saved equation?

    Thanks,

    Shane

  2. Hello and thank you for your purchase. Are you talking about EQ Editor 1.02 or EQ Editor Lite or a different app? It was basically export only for EQ Editor v1.02, but the new version 2.0 has been submitted and should come out in 10 days or so.

    In any case, with EQ Editor Lite and EQ Editor 2.0, you can save them in a local directory by first using the “bookmarks” button on the toolbar, and then clicking the “Save current equation” line in the table view. This should let you edit that line to give it a name and then you click the green “+” sign to tell it to save and click “done” to actually save it. You can retrieve it by just clicking on the name you gave the equation.

    You can also import MathML files into the app by syncing your iPad in iTunes, going to the “apps” page, and telling iTunes which files to add from there. After you’ve added the MathML file, you should be able to load it by clicking the “+” icon and choosing the file name from there.

    Finally, if you email the MathML file as a .xml file to yourself (Mail app has a problem with .mml files) you should be able to choose to open it in EQ Editor or even EQ Reader from the app and it should open that way.

    Hope this helps and let me know if you need more information. Short answer: if you’re using EQ Editor 1.02, wait until version 2.0 comes out in 10 days, otherwise, you should be good to go.

  3. I just bought your program. How to input derivatives. I do not see a menu for them.
    Thanks in advance

  4. Hello and thanks for the purchase. Assuming you’re talking about the full version, you can get all of the ‘, ”, etc. by pressing and holding the “,” button for 0.5 secs and then releasing. A tiny window should pop up with a number of punctuation marks including the primes. If you want the partial derivative, then that can be reached by doing the same thing (pressing and holding for 0.5 secs) to the “/” button.

    Some of these marks and other special symbols can be reached by going to the script tab in the keyboard at the bottom and pressing and holding the aleph or ! buttons as well. Let me know if this helps or if there’s still a problem for you, or if you have any other feedback on this.

    Thanks!

  5. Thanks for your reply. I was able o see the rest of the symbols including the partial derivative one, but I can not see the simple one variable derivative. I have to input it like d/dx manually and then open parenthesis to input the function. (time consuming ). Am I missing something?

    Also, is there any user guide or manual?

    I am using The iPad. Also, I think your website in safari is using onswipe and has some shortcomings. (not your site but onswipe itself). How can I display the normal site?

    Thanks again.

    • I had something like that in the previous version, but I didn’t add it when I did the re-coding for the new version. I will look into adding those back into a future version but that won’t be for several weeks.

      The help file is reached by pressing the “i” button. It’s in the lower right hand corner of the toolbar when you’re in view mode in the regular version and edit mode in the lite version. The swipe style is part of the default settings for wordpress. I think there’s a link on the first page after swiping that lets you choose the normal site.

    My question is how to insert matrices with more than two rows? I’m using version 2.0 of EQ Editor.

    Thank’s
    Kurt

    • Hello Kurt, thank you for your question. Unfortunately, there is no way to do that in EQ Editor as I haven’t written code to handle larger matrices. I believe it may be possible to get it to display in EQ Reader if you know enough MathML (or TeX) to build a larger matrix in a different program and then paste the code for it into EQ Reader, but I haven’t tested it.

    i HAVE A DISABLED SON. HE HAS FRIEDREICH’S ATAXIA AND CANNOT WRITE. HE USES A COMPUTER WITH DIFFICULTY DUE TO POOR HAND-EYE CO-ORDINATION. WE BOUGHT AN IPAD FOR HIM MAINLY TO DO HIS MATHS IN CLASS EVEN IF HE ONLY DOES THREE OR FOUR ALGEBRA PROBLEMS THE ENTIRE PERIOD. HE IS IN GRADE 10.

    MY PROBLEM IS THIS: I PAID FOR AND INSTALLED THE MATHBOT APP ONLY TO FIND OUT THAT THIS APP CAN ACTUALLY ONLY TYPESET AN EQUATION. THUS YOU CANNOT DO THE MATHEMATICAL PROBLEM AND SOLVE IT STEP BY STEP AS IS EXPECTED FROM A MATH STUDENT. iHAVE ALSO INSTALLED AND PAID FOR OTHER APPS WHICH MOSTLY TURNED OUT TO BE SOLVERS OR CALCULATORS. CURRENTLY, WE USE MICROSOFT WORD’S WINDOWS 7 EQUATION PROGRAM WHICH IS EXCELLENT.

    I AM LOOKING FOR AN APP WHICH HE CAN USE TO PHYSICALLY DO SOME MATHS EXERCISES FROM HIS TEXT BOOK ON IPAD AND IMPORT THAT TO AN APP LIKE PAGES TO BE PRINTED OR SAVED FOR HIS TEACHER TO MARK.

    CAN YOUR APP (EQEDITOR) DO THIS OR DO YOU KNOW OF ANY APP THAT CAN HELP ME?
    PLEASE! PLEASE!

    KIND REGARDS

    • Hello Elsabe, I’m sorry to hear about your son’s disability. From what I’ve seen, most of the other programs like this on the iPad run on TeX, which is okay, but probably not something useful to people who are still learning math as it is geared more towards the University and publisher type of person.

      Eq Editor is similar to the Windows equation program or the MathType program in that it uses symbols to let you enter and navigate the equations you are laying out (unlike Mathbot which uses TeX macros like “\over” etc). It handles multiple lines so you could go line by line through the problem and give the solution to the problem. It also lets you print directly from the program, assuming the printer is set up to handle wireless printing, or you can copy your math to the clipboard as a picture and paste it into Pages.

      My suggestion would be to try EQ Editor Lite (which is here on iTunes). It is $1 cheaper than the pro version and has a simpler interface, but the main difference is that the pro version requires the user to do a “press and hold then release” gesture to access its extra symbols. This might be annoying for your son.

      In any case, I hope this helps.

    Is it possible to export to TeX? If not, can you add that feature?

    • Hello Ken,

      I had some (limited) ability to export to TeX in the 1.0 version, but in the 2.0 version I changed the data model to use a DOM Tree rather than a custom datatype. This led to a number of improvements, but it made it much more difficult to convert to TeX as I went from have a custom model that could handle it to something that would require a full MathML to TeX convertor. While there are stylesheets that would let you do that (see: http://www.orcca.on.ca/MathML/texmml/mmltotex.html ), you currently don’t have access XSL engines unless you import alot of extra libraries that are available on iOS, but not officially supported due to their memory requirements.

      • Ken permalink

        Thanks for the answer. Even without that support, this is terrific math editor for iPad. My interest in TeX is primarily to support easy import into our learning management system: we can use MathJax to translate the TeX to MML for display in the browser. But MathJax will also take the MathML directly–it’s just a lot more to copy and paste and impossible to edited directly.

    Hello,

    I just purchased the pro version of EQ Editor for the iPad and I read through your information page, included in the app. However, I’m confused on the layout and operation of the app. The purpose of my buying the app is to write my own practice exercises for my algebra class. But I’m having trouble with the instructions you gave for importing data into the app. I’m using the app in conjunction with the Pages app. I use the Pages app to write my text (e.g., directions for each numbered math exercise in my textbook). I copy this text in the Pages app in order to paste it into your EQ Editor app, but I don’t see how this is possible.

    I read the importing equation data paragraph on your information page, but it is very unclear to me. It seems I can only input data to a new file or edit data in a saved file using the edit button, not the view mode “+” button.

    I choose to use the Pages app to write any long text I need because the keyboard layout in EQ Editor is strange, and not user-friendly for typing large amounts of text (e.g., instructions, explanations, etc.).

    Please help. Thanks!

    • Hello and thank you for your purchase.

      For what you’re wanting to do, the best method is to probably type most of your text in Pages. When you need a math equation, set it up in EQ Editor then go into “view” mode and click the “camera” button. This will turn the math into an image and let you crop and save it to the clipboard. From there you can switch back into Pages and paste it and it will work just like any other image.

      Most of the import type instructions you were reading are geared toward taking the MathML data used to typeset math and importing it into EQ Editor or exporting it from there. While you can copy it to the clipboard using the “copy” button, if you need the files themselves, the easiest method is to plug your iPad in to your computer and move files using iTunes. More information on that is on the official site.

    Thank you for responding. Unfortunately, after using the app for over an hour I cannot seem to get it to save the equations I’ve created in it. Using the “edit” button to create the equation I’m left with selecting the “done” or “copy” buttons. And in an attempt to figure things out I tap the “done” button. From this point I tap the “folder” icon to export the file, but where is it being exported to? It doesn’t give me an option to choose. I assume it is being saved for me to view in iTunes, using iTunes File Sharing. Now I see the same equation I just created, but how do I save it in your app? I ask this because I’d like to refer back to it in the app. I tap the “camera”, “crop”, and the “save to clipboard” buttons, but these don’t seem to save the file either. Also, I’d like to create more equations and save each one in the app. I assume the “bookmarks’ icon is used for this purpose, but the only thing I see there is a file I created somehow, which I tried to delete, but it will not delete. At this point I want my money back, unless you care to rewrite your instructions in a more thorough format, explaining each feature and detailing how things work in your app. I have read and reread the information page included in your app, and I’m still confused. Hopefully, you can write back with clear instructions. I’ll tell you exactly what I need to do.

    I need to write practice exercises for my algebra class. Each exercise needs to show the exercise number and the exercise itself. After this information is in place, I need to have this copied in a WYSIWYG format to paste into my flash cards app. For example, if the exercise is x + 2(3) = 10, solve for x, on the front side of the card I need to show the following details:

    Section 2.1
    Solve each equation, and check your solution
    9. x + 2(3) = 10

    When using your app to “crop” and then “save to clipboard”, it will not paste into my flash cards app, in a WYSIWYG format. It will paste into my Pages app as an image file, but this won’t do for my needs. And with the equation image pasted into the Pages app I can copy it from there and try to paste it into my flash cards app, but only the file name of the photo is pasted (e.g., pasted-image.png). For now I have discovered a way to get around this by using my devices default method of taking screen shots, and then cropping the image in another photo app I have installed. This photo app automatically creates a copy of the cropped image into the devices “camera roll”, which I think if your app did this it would save me the trouble of using so many apps. And yes, after all of this I can finally copy the image file from my devices “camera roll” into my flash cards app. However, I still don’t have the equation saved in your app. Every time I want to write a new equation I find myself writing over the previous one, and not knowing how to save each equation leaves me with no work saved in your app. All of this is for the front side of each card in my flash cards app.

    The back side of each card in my flash cards app needs to show the work of each exercise (i.e., show the work of each expression or equation being solved). I need this written out line by line. For example, if the exercise is x + 2(3) = 10, solve for x, on the back side of each card I need to show the details of how to solve this exercise as follows:

    x + 2(3) = 10 Multiply
    x + 6 = 10 Subtract 6 from both sides of equation
    x = 4 Solved

    I need to do this for each practice exercise. I realize your app is not a flash cards app, and I don’t need help with my flash cards app. I just want to get the information from your app, in the equation editor styled format (WYSIWYG) or an image file saved to my devices “camera roll”, to my flash cards app. And I’d like this information saved in your app for future reference. I need this quick. My classes start next week. Maybe you could make some videos and post them to your website or YouTube. Otherwise, please explain in detail how I can use your app for the needs I explained above. I hope I was thorough in the explanation of my needs. If your app will allow this, I’d like to know how. If not, I’ll contact the App Store for a refund.

    Thanks

    • I’m sorry that you seem to be having these issues with the interface. I will try to respond to your questions via view email as I think it will be better than using the comment system. I think you are right that a quick start post or something would probably be useful.

    I’m an economist, so sometimes we use phrases (with spaces between words) as variables. Any chance you could offer a space key?

    • Hello,

      There is a space key, though it may not be the standard symbol for it. It’s the blue button located to the right of the equal sign. Also the same symbol in the lower right corner in the grey bottom buttons gives you a choice of three space sizes. You can reach the extra characters by pressing and holding the button for 1.0 secs and then releasing.

      Hope this helps!
