App Store Reviews
“Best app among similar ones I love this app so much! After installing and uninstalling a dozen of similar apps I tried this one and it hasn’t disappointed me in nearly 2 years. Amazing layout, no ads, I can enter as much or as little as I want. Keep up the great work!!!!”
“This app rocks! Really great app and I like the new widget. Not sure why some rate it so low. I find it easy to use and attractively designed.”
“New and improved!! I love the new widget this app has. Very discreet, yet let’s me know my next cycle is! The app itself is customizable, and very easy to use! Loving the new improvements!”
“I downloaded several apps for NFP and this has been the best (and it’s free!). I almost paid for a subscription to natural cycles and am glad I waited to test them both out at the same time. I put all the same information in both apps and lady cycle accurately determined when my period would start and was only a day off estimating an ovulation date. I’ve researched how symptothermal methods work and I could see the program utilizing the same methods, including advising to abstain from sex the three days after your temperature spikes. I’m only about two months in, but very pleased as someone with regular cycles trying to use NFP to avoid pregnancy.”
“Excellent Out of the apps I’ve tried, ladycycle is the most comprehensive and allows me to record the exact data I want. I found it complicated at first but the online tutorial really helps. I haven’t got to grips with everything yet but I’m prepared to make the effort just because this app is so detailed and genuinely committed to providing women with contraceptive choices that are hormone free. If I stay pregnancy free for a year I will definitely be donating!”
“Easy to use, good tutorial, nice interface, add free 🙂 Just started to use it, looks much better than others I tried.”
I have been using NFP for several years (both fertility and contraception). More than a year ago I finally found Lady Cycle, an app that evaluates reliably and applies all the rules. THANK YOU!
