One thing I wish would be accessible is the ability to send one chart at a time to my CrMS practitioner and/or fertility doctor- especially when I talk with them both frequently and they have my previous cycles on file. ### 1/5 — Unable to log in *2022-04-29, version 6.8* So after paying the one year subscription I’m able to log in, contacted the support person and receive no response . The app was nice when it was still working , very identical to the paper charting ### 1/5 — Can’t login *2021-09-25, version 6.8* We’ve used this app for years and liked it. But it stopped working this week and the website is down. Is this permanent? Would love to be able to use the app again. ### 1/5 — Stopped working *2021-09-24, version 6.8* Loved it till Wednesday mid day (Sep2021) ### 4/5 — Ok charting app *2021-09-17, version 6.8* I like how this is pretty compatible with creighton charting but it does not align with my phone! I have an iPhone 12 so maybe this app needs to be updated? I have to rotate it on my screen in order to click around and input anything. Please fix this! Thanks ### 1/5 — HELP! Not working on iPhone 12 mini *2021-07-02, version 6.8* Everything is overlapping . We switched from android to iPhone and it works on my 12pro but not on her mini please help it’s has always worked before ### 2/5 — Not printable *2021-04-01, version 6.8* Very frustrating that the email version of this chart cannot be printed. ### 4/5 — Helps get you pregnant (and not) *2020-11-29, version 6.8* My wife and I used this to help track her body signs for fertility. Using it now to bond together after having kids. Interface is a bit old. Not renewing membership for this reason. ### 2/5 — Paper Charts Were Easier *2020-05-28, version 6.8* 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. ### 2/5 — No way to chart temps or ovulation *2019-12-27, version 6.8* I studied NFP when I was married. I have used paper charts forever but wanted something digital for when I travel. This app appears to only track mucus and your period no way to track temperatures which is a huge part to charting your cycle. Sadly this app isn’t for me. ## Frequently asked questions about NFP Charting ### What is NFP Charting?
