Cant figure this app out!!

I really want to like this app because it is simple and basic. All I want is an app where I enter my BG readings and the app keeps track of them and then lets me produce a report for my doc. I dont want it to track my meds, food, exercise, etc. like so many other bloated apps do. This app basically does what I want but it is confusing. First, there are two apps one is free and the other is $1.99. What is the difference? I bought both and even did the in-app upgrade to get rid of ads. Looks like both apps are the same though. Did I waste my money on the full app? Second why does the app want me to track my weight every time I check my BG? All I really want it to do is keep track of my BG. Anyway I will use the app because it mostly does what I want but it is kind of strange. Hopefully a future update will decouple BG and weight.
