I apparently purchased TWO KetoDiet apps - KetoDiet and KetoDietBasic. I have proof in the form of two receipts from the Apple Store that I paid for what I thought was the same product twice, first in Feb 2017, then later for an enforced update. The app (not sure which one), told me I could not use it unless I updated) in July 2017. So it appears that I paid twice to use KetoDiet.
My review experience with these apps has been upsetting because their surprisingly unpleasant “customer support” told me it was impossible to buy it twice, but I guess they FORGOT there are two KetoDiet apps with the same icon (confusing), but one is a Basic version. I still have them both on my phone. Instead of being helpful, and suggesting maybe I’d gotten the two versions confused, they were sarcastic and accusatory. They threatened to report me to Apple for inventing my complaint about paying twice. I did pay twice, unfortunately, Basic or not, and I still think, like their customer service, the interface(s) are not at all user friendly. I recommend CarbManager, better interface, nicer customer service, and their free version is very accessible.
I just saw another complaint about there being two versions, both are labeled “the original” version. This is double-dipping by being intentionally confusing.
