Exceptional!!
Been using this app daily for a month now and I have not seen any bugs. I started with the free trial and made up a few things to track. Then bought the full version and transferred my tracked items seamlessly. Created a large set of new items to track and added a category or two. After a week added a few more items. This all worked as expected.
Features that stand out for me are that the badge reminds me how many items I have not filled in today, and I can export the data to a spreadsheet to do any fancy analysis that I want. The badge reminder can be set to ignore any items that I deem optional, and the built in graphing is good enough that I have not felt a great need to export the data to excel but I tested the capability.
You can make multiple entries for each item each day and they get time stamped and you can add a comment. Also you can change the time stamp so if you want to record your blood pressure at 2 pm but dont make the entry until bed time, you can set the time stamp to 2 pm, and for each item you can add a comment such as "just ran a mile" to note why your blood pressure might be high. Finally, I like that I can go back and edit entries. This helps if I made an error or if I later want to clarify something with a comment.
Setting up new items and categories seemed a bit clumsy at first but I think that it was mostly a matter of the iPad standard user interface (got the iPad only a couple of weeks before). My advice is to just experiment and the UI becomes easy and intuitive in a short time.
I have now tried hundreds of different apps from games to painting, and this one stands out as intuitive (wrt filling in the tracking data), no nonsense (does one thing well without unwanted bells and whistles), robust (no crashes), and well designed. I havent seen any iPad app that would compete with this for tracking whatever you want.
