I am using Appirater also for rating my app.Will it be ok if i append code in that to get my task done?
or is there any other way to acknowledge launching of my app every 3rd time?

Here you can store in NSUserDefault for the App launch count and can show the alert every third time app launching.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    if(![[[NSUserDefaults standardUserDefaults] valueForKey:@"firstTime"] isEqualToString:@"Yes"])
    {
        [[NSUserDefaults standardUserDefaults] setValue:@"Yes" forKey:@"firstTime"];

        [[NSUserDefaults standardUserDefaults] setInteger:([[NSUserDefaults standardUserDefaults] integerForKey:@"ApplaunchCount"] + 1) forKey:@"ApplaunchCount"];

        [[NSUserDefaults standardUserDefaults] synchronize];
    }
    else
    {
        [[NSUserDefaults standardUserDefaults] setInteger:([[NSUserDefaults standardUserDefaults] integerForKey:@"ApplaunchCount"] + 1) forKey:@"ApplaunchCount"];
        [[NSUserDefaults standardUserDefaults] synchronize];

        if([[NSUserDefaults standardUserDefaults] integerForKey:@"ApplaunchCount"] % 3 ==0)
        {
            UIAlertView *lanuchAlert = [[UIAlertView alloc] initWithTitle:@"Your Message Title" message:@"Your Message Text" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
            [lanuchAlert show];
            [lanuchAlert release];
        }
    }

    // Add the tab bar controller's current view as a subview of the window
    [self.window addSubview:navigationController.view];
    [self.window makeKeyAndVisible];

    return YES;
}
