I've found it impossible (nearly) to dig through all the crap on the iPhone App Store, and I'm sure many of you have too. So I thought it would be a good idea to compile a list of good productivity apps and maybe even review them here. I'll start off with GraphCalc. It's extremely easy to use and you can graph some pretty advanced functions. GraphCalc is pretty and the customization is pretty nice. However, you can't plot your own data set on it and it's definitely not a replacement for a TI-84. There's no way to export your graphs either, other than taking a screenshot and exporting the picture. And if you have a Mac I can't really see a purpose for it since the computer comes with Grapher, in the Utilities folder. Second would be Omnifocus. It's not as well known as Things, but it's pretty well laid out. The syncing with MobileMe is pretty sweet, it makes it easy to recover backups. Some low points is that to really be useful, right now since some key features are missing, you need to have Omnifocus (the desktop version) which is $70! That's a $90 investment vs. Things' $60 price tag. PS: I searched, but if this post belongs in another thread I'll gladly ask a mod to move my post.
