Good but needs to follow TCOYF rules better
I really enjoy using this app. I just wish it adhered more closely to the TCOYF book. I dont know what rule this app uses to determine a temperature shift and/or coverline, but its not accurate. I still chart on paper because of this. This app would be confusing/inaccurate for women who have not studied the book and understand the fertility rules. Please change the temperature shift and coverline to match the book!
