I have been working on this app for 3 weeks now and would love some feedback.
My overall goal was to build something that would make creating and managing Twitter lists easier. I added the ability that you can mark how frequently you want a user to be on a certain list and Twists will automatically generate a new list for you every night. This keeps your lists from getting too cluttered and hopefully only shows you the relevant information.
The main challenge of this app was getting the local data to sync with the remote data held on Twitter. If I made too many requests to the Twitter API I would get rate limit errors and be blocked out for 15 minutes. This got to be VERY frustrating when I was trying to test and build that app.
