Not so great

I have been using this app for a few weeks now and there are pros and cons. It is one of the few apps that keeps track of carbs on the home page and even on the face of the app so you can see at a glance how many carbs you have had so far. When you are counting carbs that is a great feature. it's pretty simple to use for the most part.
My cons are that a least a half a dozen times I have logged my meal, each thing I ate and even though I hit save it disappeared after i put everything in. That is very frustrating! The other thing I don't like is that sometimes its hard to find foods and there is no way to search. On a scale of 1 to 5 I give it a 3 at most. I'm looking for another app to use now. The disappearing meal log has happened one to many times for my liking!

Some developers forget about Dev and QA before deploying to the public

1-Dl the free version, and I was able to figure it out after some poking around. Tried to enter my weight and no response, so I figured maybe this feature is locked and so I bought the full version
2-Hey I am still unable to enter my weight on the full version app, and the app is not responsive like the free version.
3-Let me try to use the "Migrate to full version' feature from the free version.. The progress circle spins endlessly.. The app is unresposive again.
4)Crap now my phone is unreaponsive too..
5) Hope you all get my point.. First impressions are what the matters the most.. That certainly did not happen here.. The app had so much potential..

Nice but flawed - DO NOT BUY TO TEST THE PAY APP

It would be a weight and carb/calorie tracker, it not so flawed.

The database organization is terrible - the names of foods are so long that you have to go three clicks deep to see if "chicken" is broiled or breaded, so it can take twenty clicks to find youir food!

You can add (some! not tuna!) foods to your Favorites, which makes it quick.

Don't count on trying out the free app and migrating your diet history to the pay app. I have an up to date iPhone 4, and it does not work. Support acts (?) dumb about he problem, and tells you to do impossible steps like backup the data and restore to the pay verion. (This function is disabled in Free.)

Watch out - it will often jump back to the first day of the month, so even though the current day is highlighted, your weight and foods go on day 1. You cannot change tht date on an entry and once you make an entry, IT CANNOT BE REMOVED. Don't make any mistakes!
