The best part of this wheel is that
All the info you need is on the same screen as your input screen....so, when you scroll to enter LMP, you see the EDD, gestational age, gestational age at a certain date (very important when you know she had a certain test done on a certain date and you want to know what gestational age that date was), which trimester etc etc... ALL on the same screen. Therefore there is no need to push an extra button to get to the next screen to access the info you need. Im doing my Ob rotation and time is important. I needed something that took the least amount of button pushing to get the job done. I had the free app listed here on iTunes before purchasing this and it erroneously states that LMP as Last Missed Period. As far as I know our clinic uses LMP as Last Missed period. Therefore the free app you get from iTunes store gives you the wrong info.
