Crashes Often and lacks some basic functionality

I recently purchased Todo for Mac to better enable me to use the application across all my platforms (iphone and iPad) using iCloud. After installation, i have found that the application is somewhat of a dissappointment. It regularly crashes with the current shipping OS version, and lacks some very basic functionality, like being able to set the completion date and time of a task. It seems like this product was an afterthought, and needs some work. I would not recommend purchasing it, at this time, until it at least provides all the same functionality as the IOS counterpart, and is more stable.
