Keeps crashing and freezing!!!

I have had nothing but trouble with this app on my iPhone 6. I love the concept except for the fact that it crashes EVERY SINGLE TIME I want to add a new item to my daily food log. After it crashes I then have to go back in and repeat the steps...and it works as long as I select the exact same thing I tried the first time. If I select something different it crashes again. So every single new addition requires two attempts. That would be tolerable because I can put all my regular items in the "favourites" and can just pull from that list for my most common choices - EXCEPT for the fact that the whole thing FREEZES on me every other day and I have to DELETE IT and re-install it which causes me to LOSE ALL MY DATA!!!

I wouldnt care if I hadnt paid for it, but because I did, Im very disappointed in this app. There has been no response from the tech support so Im forced to give this review. Im going to have to buy a different app. :-(
