Dash 1.7.2
Dash is an excellent viewer for Mac OS X developer documentation (via Matt Gemmell). The searching and browsing features are great, and it’s nice to have the reference information in an application separate from Xcode.
It’s well worth the $9.99 price in the Mac App Store, but strangely the actual app is free and there’s an In-App Purchase for the “Full version”:
Dash is not free, you will have to purchase Dash using an In-App purchase. Dash is free to download so that you can test Dash out as much as you want, in order to determine if it’s the right tool for you.
If you haven’t purchased, it adds a delay and nag screen when you try to search. I’ve not seen other demo/trial apps in the Mac App Store, probably because the guidelines clearly say:
2.6 Apps that are “beta,” “demo,” “trial,” or “test” versions will be rejected
