PEMDAS Widget 2.0 Released!
November 16, 2010
Version 2.0 of the widget has been released! You can download it over on the PEMDAS Widget page. There are a lot of new features, among them a new refined interface (below), a new equation history view, and many small fixes and improvements.
Here is a link to the screencast, which covers most of the major new features. You can also read about them on the PEMDAS Widget page, and in the PEMDAS Widget Documentation.
And if you have any issues or feedback on the new version, let me know!
PEMDAS Widget 2.0 Development Update
March 23, 2010
The new update is pretty significant, and in fact the code running the widget was almost entirely rewritten. There are many new features, the biggest of which is a heavily renovated interface. Many of the features are borrowed from the PEMDAS iPhone and PEMDAS Desktop apps.
Back in Action
July 14, 2009
There is some good news today -- Version 1.1 of PEMDAS Touch has been released! Right now it's only available in the US store, but I'm working on bringing it to other stores soon.
The biggest new feature is probably support for binary, octal, and hexadecimal numbers, but there are a few other things that may be useful, an well as an updated icon and keypad interface. Feel free to send me any feedback you may have.
To see an overview of the Version 1.1, you can watch the screencast below:
I'm already working on Version 1.2, which I think may be the biggest update since 1.0. I also have something else in the works, which I hope to post more info about soon!
PEMDAS App Version 0.2.4 Released!
March 19, 2009
Version 0.2.4 is now released! This is a quick update to add a bugfix and a new version of the calculation engine, which includes a cbrt() function and changes to the way the "ans" variable works. An update to PEMDAS Touch is coming very shortly that includes the new version of the calculation engine among other things. Enjoy!
PEMDAS App Version 0.2.4 Release Imminent
March 17, 2009
Version 0.2.4 is almost finished and should be released in the next few days, sorry for the long delay. Version 0.2.4 will add a cbrt() function, will fix a bug where typing an equation like 1 + 0.1 and hitting enter wouldn't do anything, and even more importantly has behind-the-scenes updates like a new version of the calculation engine. Version 0.2.4 will be the last of the 0.2.x series of updates.
PEMDAS Touch 1.0 Released!
February 14, 2009
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):
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.
