I would like to have en mobile software programmer to make a mobile applikation with the following features.
Exact price for Android and exact price for iOS is preferred.

The app is about comparing voice frequency graphs.
On the phone you got a number voice frequency graphs. By choosing one, the phone plays the sound by the loudspeaker. Afterwords the user off the applikation, are going to imitate the sound played by the phone. The phone records the imitated sound, and makes it into at voice frequency graph, and compares it to the original played voice graph by telling how many % the sound was imitated correct.

All in all the user are going to imitate the sound/voices from the Phone, and get a score in %, off how much is was imitated correct.
