Freezes after round end but cool app

This game Is the most realistic pool app Ive played,but if ur in comp. or just shooting around the app freezes after u sink last ball. Really hope you guys can fix with an update cause me and my friends love it. iPhone 4S ISO 7.0.4 & iPad mini ISO 7.0.4 freezes on both.
