I am trying out Eisenhower GTD matrix and the design here is better and more simplified than other iOS offerings.
That said ...
- iCloud support is iffy. My iPad and iPhone rarely sync. I have tried all sorts of trouble shooting on this and my lists are different depending on device.
- The companys website is not accessible via my iPad. Sorta odd for an iOS developer.
- Some design decisions are not intuitive. For example, a category icon is required.
- Selecting the task color when creating something new is pretty, but the vertical text was difficult to figure out what do do with and took up a lot of space on iPad. Once figured out this works well, so I dont know if it is fixable.
- Items that are too long scroll back and forth. Have a couple of theses will make your head spin.
