Idea for braintraining excercises

Last night I came up with an idea for the brain training part of my game concept:

At first I had the idea of doing this exercises with a computer program on your PC, but I got inspired by a little game on my mobile phone called 'braintraining'. It is a 'Dr. Kawashima's Brain Training' copy.
This game gives you daily exercises that can only be played once a day. It also keeps track of your progress and saves the data in a calender.

I would like to use this kind of program for a few things:

-Training (reality check, prospective memory)
-Keeping track of ones sleeping schedule (by entering when you go to bed and with an alarm function which wakes you up. Also the use of the snooze function can be tracked.
-Using the sleeping schedule data for the stimulation of ‘mnemonic induction of lucid dreaming’.
-Giving the user the option to record his dreams (with sound or text) immediately after waking up.

The data of the program will be user specific. The program will generate codes(passwords) based on the user information and the progress he/she made. These codes can then be entered in the PC game to unlock new abilities.

In this way your mobile phone will keep you aware of the game and your dreams and will be a tool to help you get lucid dreams.

I think that this program should also work as a stand-alone program. People can download/order and play it. This could work as an advertisement for the game.
