As I’ve mentioned before, I’m a big fan of OmniFocus, the premiere GTD-oriented series of task and project management apps for OS X. That said, it’s not the only horse in the GTD race. I wanted to let what little audience I have know that Cultured Code’s Things is Apple’s App of the Week, so it’s iPad and iPhone apps are both free right now. They typically sell for $20 and $10, respectively, so grabbing them now, even if you may not need them now would be a great idea. They’re also running a limited time discount on the Mac version of Things for $35, about 30% off the normal price (there’s also a free demo version available from their website.)

Things has really embraced iOS 8’s design language, while keeping it’s own bit of style. It alos uses Cultured Code’s own free Things Sync service to sync tasks and projects across all three devices. The iOS versions include integration with Siri, a Notification Center widget, and Share Sheet extension for quickly adding tasks or info from anywhere in iOS. The Mac version includes a quick entry window that can pop up from a keyboard shortcut, and a Notification Widget showing your current task list. It even supports Handoff, so you can quickly jump from Things for iOS to OS X.

I’d highly recommend checking this out because this promo won’t be around for much longer.
