Help457 – Kids Learning to Read - Little Reader CVC Words Review

I have purchased this App and 2 others from this company. All three Apps will not open on my iPhone. They try to open for about 2 seconds, then nothing. I have tried to reinstall with no success. Does anyone know how to fix this? I would really like to use the Apps..., thanks
