App crashes after launch – Su Chef: Healthy Recipes by Ingredients, Diet or Food Allergies (Paleo, Vegetarian, Gluten Free, Low Calorie Recipes and more) So you Always Know What to Eat for Dinner Review

The idea of the app is phenomenal. However, like the person right above, the app started to crash after I installed/bought the full pack. Not sure if this is an app problem or an apple problem. Any help would be truly appreciated!
