Where did you get this app? Is your phone jailbroken?
What do you mean by "reset"? What Apple means by Reset is to reboot iOS, which is done by holding the HOME and SLEEP buttons until an Apple logo appears, about 10 seconds of holding.
If you mean to clear the phone, it's in the Settings app, General/Reset - Erase all content and settings. This should take about 5 seconds on a 4S.
If you mean something else, what do you mean?
