Dropkick is a simple, elegant iPhone app we covered a while ago that lets you manage to-dos and sync them back through the cloud to a free Mac companion application. Dropkick, in fact, is free if you want to enter up to 10 tasks, and it goes paid to unlock unlimited access to task management. The app is really minimal and focused on entering new tasks, and completing them. Cloud sync happens through a free Dropkick account, and it’s really fast. For many, Dropkick has become the best way to quickly capture and manage to-dos, keeping them always available thanks to the comfort and reliability of online sync.

An update to the app was released earlier today, which now happens to also be available in the Mac App Store for $4.99. While Dropkick retains the underlying philosophy of simplicity, the developers have implemented a much requested feature: Lists. You can now organize your tasks in different lists or “projects” – something like “personal” and “work”. But that’s really it: no additional contexts, tags or due and start dates. Just tasks, lists and cloud sync.

The Mac version lets you navigate between tasks with the keyboard, the iPhone app now can add tasks one after the other without going back to the homescreen. Again, cloud sync works just fine.

Dropkick is a free download for iPhone, with a $1.99 in-app purchase to unlock unlimited tasks. A free trial of the Mac version is available on the developers’ website, and you can buy it for $4.99 on the Mac App Store.
