It will suffice

My fiancé and I began nfp a few months ago. We've been taught to use the Creighton model (NaProtechnology and FertilityCare). As she's the one that makes the observations, I record the charting. I greatly appreciate the idea of not having to carry a chart around on our travels. The space to leave comments is great for observations. My only wish is that there could be an offline component (iPod user) so that even when I'm away from wifi, I could chart and sync up later. Is this possible? Five stars if you can do that!

Replaced my paper chart

Much more convenient than stickers. Compatible with Creighton chart. Has feature that allows you to email entire chart to yourself or teacher. Can comment as much as you want, too - especially great for yellow sticker users. Customer service is very fast and responsive as well and allows you to freeze time if you’re pregnant.

Paper Charts Were Easier

This app doesn’t make the charting process easier, and I honestly miss my paper charts. While I’m somewhat glad this app exists so I can continue to chart using Billings, it’s just too expensive for what it is. It crashes and freezes constantly. The losing graphics and design are unpleasing to look at. As another reviewer has stated, it’s annoying to review previous charts when you click “View All” because they are in order from oldest to newest. It’s just not a well designed app.
