Simple, easy to understand
I like that it’s set up for three different methods of calculation depending on your insulin sensitivity at various times of the day. I also like that it saves your settings instead of re-entering them every time. Would love an and be willing to pay a decent amount for IOB and exercise adjustment to be included as well as it keeping your records permanently in the app for your review. I had the Rapid Calc app but lost it when I got a new phone and it’s no longer available in the USA App Store. I’m dying for someone to duplicate it. But in the meantime, this is about the best anyone has to offer here in the US App Store, not to mention, it’s free with no adds. Can’t beat that.
