    It sounds like you’re not actually terminating the app, but backgrounding it. When you launch the application again, it continues from where you left off: showing the drawn shape.

    If you’d like to clear the shape when the application moves from the background into the foreground, you could implement applicationWillEnterForeground: in UIApplicationDelegate (see here) or you could observe UIApplicationWillEnterForegroundNotifications (see here).
