This is a good idea, and I could really use something like this, but there's some problems.
i. The interface is a bit counterintuitive. It's very easy to delete tasks accidentally, and not all that clear how you navigate the different options.
ii. The timer in the menubar only ever shows 0:00, but it does show the time when you click the menubar icon
On the plus side, its very nicely presented. All the graphics are very nicely done.
I'll revisit this when it gets a bit further along in the development cycle. I like the idea, but it's not quite polished enough on the usability side for me just yet.
I'd happily pay $3.99 for this if you can get it a bit more user-friendly.
