Next Day

Thanks to Wikipedia, Xavier Gourdon & Pascal Sebah and AT&T, I have my initial list of memorization candidates:

I’m thinking that the app would have two main views.  One to display a list of numbers, and the other to test and train you on each.  A settings view may be necessary.

I’m storing my numbers in an SQL database, although I could easily have used a different mechanism for storing and retrieving.  With the SQL database, I presumably could, down the road, let the user add their own numbers or access a network database of numbers.  As it is now, there doesn’t seem to be any downside.

Here’s the screenshot for the first view.  The biggest challenge I had to deal with was getting the app onto my iPhone – I really wish Apple would make it a whole lot easier.

First View

Due to the width of some of the numbers, I have decided that the app can only be used in landscape orientation (the user has to hold the iPhone sideways).  I may revisit that decision later.

Touching any of these numbers, the user is moved to the next view.  My thoughts are that the view will sport a fulltime numeric keypad, plus an ara at the top that would be able to display the entire n digits of the numbers.  As you type a number, you will be timed and you will be corrected if you type a wrong digit twice in a row.

Now to program the second view.
