So far I found Joke Book to be an ideal app with clean user interface. However, they only have 10 pre-loaded jokes in each category (as being posted by someone on iTunes App Review). So the entire idea of this app is for you to add your own jokes. Wonder is there any jokes app out there that offered hundreds of joke which can be viewed offline (online to update more jokes), have multiple selectable categories, ability to add/edit own jokes, ability to add favorites, features to email a certain jokes to someone else. Similar features applid for Movie Quotes. I also checked for Movie Quotes and noticed that their user interface is quite badly designed and you can't view a list view of your added favorites. Instead, once you tap on the favorite you can only read your added items linearly. So far the AppStore is seriously lacking these apps with nice user interface and features. I will develop one IF I could... Sadly I used Windows.
