Early tester feedback

Quietly working for the people who tested it.

CarbZen is brand new on the App Store. Here's what TestFlight users said while we were building it.

"I was able to easily figure out what the carbs were in pretty much any meal I was having. I never needed to describe anything — it seemed to always figure it out, even with a lot of components on the dish. My control has been better with the help of CarbZen."

"Fast to find the carbs and macros in anything I have got in front of me. Much easier for me to make good decisions on my keto diet."
