Review
Since it's only available at $0.99 for today, I thought I'd post a quick gallery of screenshots of the initial setup of Checkmark which should show you a lot of the care that went into making this app. After I've played with it for a while I'll post a more thorough review.
My initial impression is that it's a great looking app with lots of little touches (like the ability to set the range for how far from your location the app's "radar" should alert you) and better usability than Apple's own Reminders.app included in iOS5.

- This is the first time I'm using the new Carousel feature added to WordPress' Jetpack plugin. They look pretty good in my opinion. Let me know if you see any issues or bugs. ↩
