I've been waiting a long time to say this -- PEMDAS is now on the iPhone (and iPod Touch)!

This app has been in relatively quiet development since last June, and I really hope the wait has been worth it. I've been using it for the past few months, and I really like it.

However, unlike the widget, this app won't be free -- I've priced it at $4.99. I put a lot of thought into how much it should cost, so hopefully you will find that it's well worth it.

So, to buy it, you can visit the PEMDAS page on the iTunes store. And for more information, visit the PEMDAS Touch page on the Donkey Engineering site.

I've also linked the screencast of the PEMDAS Touch app, hopefully this gives a good idea of how it works (it's very similar to the widget):

PEMDAS Touch 1.0: An Introduction

An introduction in how to use the app, 4 minutes long

And here are a few screenshots:

The Keypad tab.

The Variables tab.

The Equations tab.

The Settings tab.

As always, I hope you like this app too, and please don't hesitate to send me any feedback you have on it.

Finally, like I said in the previous post, the widget is still under in development. I'm trying to have the new version out sometime in the next few months, and I'm sorry it's taking so long, because the widget is really hurting for an update. But hopefully now with the PEMDAS for iPhone release, you can see where some of the time I would have otherwise been working on the widget has gone.

Hey everyone, not sure if you've noticed, but I've gradually been moving all PEMDAS related pages over to the Donkey Engineering site. Today I uploaded the new page for the PEMDAS Widget. Besides being a lot nicer than this page, and I also added an update on the status of development on the widget.

I also released an update to the PEMDAS App, Version 0.2.3. I definitely recommend checking it out!

I haven't quite figured out what to do with this site. I might move this news section over to a news section on the other site, or leave it available as an archive here. I'll leave this page up for the time being, but pretty soon I'm going to have it automatically redirect to the new site.

Equations App 0.2.2 has been released! (On a side note, I changed the name of this app again, it used to be called Formulas). Visit the Donkey Engineering site to download it. I definitely recommend everyone who uses PEMDAS to check it out.

Also, this 0.2.2 update was not the major update I was referring to in the last post. That one I'm still working on, and I'm hoping to have another release out sometime in the very near future.

Formulas App 0.2.1 has been released! Visit the Donkey Engineering site to check it out... there's still a lot of work left to be done, but I think it's a pretty good update.

In the meantime, I'm going full steam on another big update, I hope to have it out soon. I hope everyone is having a good holidays!
