Awesome App! Great Update :)

No extra clicks lends itself to use at the bedside! It's just so convenient to use!

Love the simple and easy to use interface. The recent update is great, hope the author keeps it coming!

Recently downloaded the EM DDx also and it's a great tool too!

Won’t take a reading

My IQ is in the 99 percentile but maybe I’m just dumb. I can’t figure out how to take a reading with this app. I get all different kinds of problems I could have with a nice looking image with information but no way to take a reading.

I clicked on the support and I got a box to put in my Feedback but when I submitted it, even though it was the first time, it said I have used the maximum limit for entries.
