Ratings and Reviews



Great, simple app. Would like to see dates descending instead of ascending after hitting the "view all" button. To see the current month you have to scroll all the way to the bottom.

Nice to have


Use this for charting Creighton but it works fine. My biggest complaint is the file it emails. It doesn’t send a file that can be printed. Please have it send a pdf or any printable file. Would love to keep us this app but if it cannot be printed for my doctor, it’s useless.

Using this app for the Creighton Model


I am a FertilityCare Practitioner for the Creighton Model of NFP. This app makes charting so convenient. Although it's for the Billings Method, I have found it to fit my needs. I like that it's simple and to the point. This app is not for couples trying to chart without instructions. You need to be getting one on one instructions from a teacher in your area. The only thing keeping me from continuing is the price. I would be more likely to use it if the price was 99 cents a month. Great app and I hope Dr. Hildgers follows suite. Thanks!!
