iPhone 4 Applications

Hi, I am looking for someone that can write two applications for iPhone 4. Application 1: The user taps (using UIButton) on the screen twice and the will write the time duration between taps to a local file named (this will be refered to as “time”). After the second tap the program will ask for the user to enter in a textbox a number (this will be refered to as “N”). After pressing OK the program will save both time and N to a local file name “[login to view URL]”. Application 2: Four threads that will work in parallel: 1. This thread will read the input signals from the microphone and will fill a buffer in memory of the last 10 seconds of audio sound. 2. This thread will receive two taps (again using UIButton) from the screen and will save the time duration between taps in a file “[login to view URL]”. After doing that the thread will wait again for another set of two taps and will perform the same action and so forth. 3. This thread every 2 seconds will go over the 10 seconds of memory buffer and will calculate the average sound level and will put the result in the file named: “[login to view URL]”. 4. This thread will look for a file named ”[login to view URL]” and if the file exists it will vibrate a short vibration as long as the file is there if it cannot find this file it will do nothing. NOTE: The applications has to be developped in a MAC OS Snow Leopard so the Xcode has to be for Snow Leopard also. If you do not have the Xcode 4.1 for Snow Leopard you can download it from: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL]
