Sextuplets free

We had the application loaded on two of our phones. It freezes on one phone and on the second phone you have to exit the application to go to the next round. We like the game and we wouldve given it 5 stars but it just doesnt work well on an iPhone. We tried deleting the app and reinstall it several times and nothing changes.
