Visual progress is important, and it's currently done in the following way: when you complete a routine, it goes away, and it stays away until it requires your attention.
The second version will give you exactly what you expect: a historical chart of your progress, and also a nice surprise: a view to seeing how you're performing on all of your routines.
Haha, thanks! I watched the WWDC sessions to learn about the frameworks, features and see the intricacies of Interface Builder. And then spent a lot of time in iOS developer docs, stackoverflow, and cocoacontrols.com.
For the website, it was designed in photoshop, and coded using Zurb Foundations, SASS and Skrollr.js.
I'll be doing a post on how I got started on iOS and lessons I learnt to help others get ramped up quickly. So look for that in the next few weeks!
Thanks for the feedback! This is definitely something that's on top of the priority list. The first version collects the history, and as soon as the second version is released, you'll have a new "Performance" view so you can see how you're doing on all of your routines, as well as performance graphs for each one.
