I hate this app

Reviews looked good for most part but there was no trial period to see if you liked it. So I had to pay for it to try it. I knew I had wasted my money after just a few min! Food lists are ridiculous. Searches take you to another list that you have to scroll forever to find what you are looking for. Obviously the developers of this app never were on a diet and tracked their food intake. Awful, awful, awful.... too bad I can’t give it minus stars, guess I will settle for 1 star, but it does not deserve even 1.

Unable To Sync Devices

This is one of my favorite apps. I use it several times a day tracking what I eat and drink. It keeps me on track at maintaining my weight. I initially began using it on my iPad and since have acquired an iPhone. I would like to be able to sync the two devices, or at least transfer data between the two, but am unable to. Possibly this can be a consideration for futures updates?

Searching for food is horrible!!!

It takes more time to find the foods in the horrible food database search than to eat the meal. Imagine this, you have a 6 oz Sirloin beef steak for lunch and try to get it in the app. You search for "sirloin" and hundreds of entries come up. The first 23 (I counted) all say "beef, bottom sirloin, tri-tip ro..." you've got to pick one to see the full title to figure out what you want. Scrolling down through the list of hundreds of results, I notice there's pork, veal etc... So I try searching for "sirloin beef" which produces 5 results, not a one of which is nothing but sirloin beef, but instead all kinds of fancy vegetable combinations to go with beef. I try searching for "beef sirloin" and find NOTHING!
All of these gazillions of options should be question/answer not separate listings. I never did have the patience to find a way to do a plain 6 oz sirloin beef steak, so I had to choose "Restaurant food, beef steak 7 oz" (but it didn't say which restaurant) which had 0.0 g of carbs, whereas the 10oz sirloin in the same list had 23 g of carbs. It never did say which restaurant!
