Usability: On the home page, you could have made the display of times internally consistent by putting it in an accordion. Right now, displaying everything in a bulleted list is very unfinished compared to the rest of the application, as well as an inefficient use of screen real estate. You could increase efficiency by adding a way to schedule workouts for multiple days, as it takes a long time to input a days worth of workouts. On the stopwatch page, having all of the workouts on small buttons aligned to the left isn't a great use of screen real estate. In addition, it's initially unclear what happens when you hit reset--am I overwriting times? Also, there's no indication how many repetitions the athlete has finished, though you can tap their name multiple times. The Group Results tab takes all times from all workouts that an athlete did on a particular day and plots them, which will be problematic for athletes that complete in multiple events. Therefore, it will be difficult to get much out of the results page if the coach can't somehow filter by workout.
Completeness: There are definitely some bugs that need to be worked out still. If I delete an athlete, all of his/her results don't also delete. In addition, if I select all athletes for a workout and go to immediately create another workout, the text still says ""deselect all""  and the box isn't checked. In addition, I got some javascript errors when I initially tried to plot workout results.
Overall: Though your final product was missing many elements, you identified a number of ways that your design could be improved in the final interview.
Thanks for all your hard work this term!
