Welcome to the support/contact page for the iPad app. The developer can be reached here and updates about this app will be added here as well. The app is now live and can be found on the iTunes store here.

    I just purchased EQ Editor on i-tunes and my first impression is that it is a great app with an intuitive user interface. A limitation, however, from my point of view, is that I did not find out how to use square roots in my formulas, which I really need. My apologies if I have missed to find how to do it. If it has not been implemented yet, please consider to do so in one of the earlier updates. Thank you.

  2. Thank you for your purchase. I did, unfortunately, leave square roots out of the first build mostly because by the time I noticed it was missing I was at the point where adding that kind of feature would cause another long round of debugging.

    I am planning on adding it in the first update I think.

  3. Just an update, I’ve posted 1.01 which has 2-, 3-, and 4- roots and it is waiting for review, so it may take a few days or a week. If I add n- roots, it will be at a much later date as those are more complicated because they do not have existing unicode values that I can use.

      Thank you very much for your quick response. This will help a lot, and I am looking forward to test this out. Thanks again.

    Great app. But it looks like its missing subset superset signs. I need those, so it would be great if you could have them added.



    • I can certainly do that, though it will most likely be in the next patch (along with any other feedback between now and then). I will post here to let people know when it is released, but most likely 7-10 days.

    Thanks, that would be very useful. Other than that this thing works great. Thanks for creating it.

    You really need to improve the quality of the formula, when pasted in keynote they are unaceptable. The only value this program has is if the formula can be exported or copied to a presentation, paper etc. So this should be your priority……..

    • Thank you for your feedback. Most of my testing was done by exporting into Pages, and the PNG files seemed fine to me, although I didn’t spend as much time working on Text only. However, you may have come across something new. Could you please explain a bit more about what were exporting. For example, were you using PNG or Text mode to export, and also what was the resulting issue with the display?

      • Dr. Ray permalink

        Copy and paste in keynote, and you will see the formula, looks good, but them increase the size to the whole page, and you will see all the pixel

      • I can see how that would be a problem. This happens because the output is as an image, not text. The distortion happens pretty much any time you take a smaller image and try and make it larger. The only way around this would be to make the image have a very large number of pixels (so basically be a very large font size). I currently don’t have a way to adjust the image size, but this is something I will look into in future versions.

  7. Just a final update, but the new free EQ Reader app has the ability to zoom and crop the equation before sending the image out. This is probably the best solution until more features are added to EQ Editor.

    How do you go to the next line ?i don’t see a carriage return key!

    • Unfortunately, with the 1.0 version you have to edit things a line at a time. I have finished writing the code for multiple equations and it will be in the 2.0 release, but it probably won’t be out for a few weeks yet as there are other features I am adding.

    I would like to be able to read the “welcome” screen and the help information WHILE I have the editor open (maybe side by side), so I don’t have to keep toggling back and forth to find what I need, try to implement it, then toggle back, etc.

    Also, it would be helpful if the help screen would “remember” where I was last. When I go BACK to it, it brings me to the TOP of the document, and I have to scroll down to where I was…Help is not very user friendly just yet.

    • Thank you for your feedback. I will do some work on the help system in the next revision. Feel free to let me know if there you have any other feedback or issues with the program.

    Hi, Sorry if this seems stupid, but in most of my work with your app I find myself just wanting to create the equation, expression, whatever…and then tapping and holding to activate the “Copy” functionality built into iOS. Then off I want to go to my document and tap and hold to bring up “Paste” to insert it into whatever document I am composing. The functionality you currently have in your app is great for more demanding composing situations, but normally I just want to get in and out of your app and back to work ASAP. I am assuming there is a good reason why this functionality is not available, but thought it was worth a question.

    Best, Mr. Luigi

    • Hello Mr. Luigi,

      It is a good question and I have thought about it some. To answer your last question, the reason why the app doesn’t work like that is because there isn’t support for complicated math built into iOS. What my program does is gives you an easy way to enter MathML into the a data tree, and then it takes the MathML back out and turns it into an image. I have some ideas about how to make it work more like the text views work, but they involve probably 2 months of doing alot of low level stuff like testing exactly where your finger taps on the screen and turning that into information the program can use to figure out exactly which equation or math symbol you’re tapping on. By the time I had finished 2-3 months of training the OS to draw complicated math onto the screen, which it didn’t know how to do either, I was needing to move on to something else.

      Hope this makes sense, and I will try and do more work on it in the future but I have another app or so in between then and now.

      • misterluigi permalink

        That makes total sense. Thanks so much for the explanation and good fortune with your future app endeavors. Cheers, Mr. Luigi

  11. Nice WYSIWYG tool for making electronic equations. I only miss the Greek letter Ω (ohm, resistance).

    • I’m glad you like it. The Ω should be there. In the case of Lite, it will be at the bottom of the full Greek letter menu with the αβγ symbol.

      In the case of EQ Editor Pro, the Omega key is available on the keyboard at the bottom of the edit view. You just need to switch it to the Greek keyboard tab by pressing the αβγ button. If you want capital letters, you should press the shift key. To view additional options for these keys, press and hold the key for 0.5s then release.

      There is also a reverse ohm symbol available. To reach that, you select the special characters keyboard tab, which is the third keyboard option with the script letters. Press and hold the ℵ symbol in the bottom right for 0.5s, then release. A view will pop up containing the Ω and ℧ symbols.

      Hope this helps!
