    I just LOVE the update, correct all the issues and layout I was crituc about. I would only advise it to include the symptothermal method beyond the NFP, and maybe put basic and advanced mode for manual changes (like determining end of fertile period)

    The app doesn't indicate fertile days and doesn't predict ovulation or even confirm my ovulation when it's very clear from temperature/mucus data...

    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. A couple of negatives...1) the design, the woman silhouette put me off at first, I really liked the simple, clean design of natural cycles. Worth it though, because it works. 2) most importantly, I haven't found a way to share the app with my husband. I really liked that natural cycles had a log in so he could've downloaded it too and followed through my account.

    It's a shame that a comprehensive app with so much potential has an interface that is clunky, outdated and difficult to navigate. To be fair, I have similar negative observations about even popular apps like Ferility Friend, though Lady Cycle could be much superior thanks to its adherence to highly efficient Sensiplan rules (a rarity, especially on Android), and I would be using it right now if it wasn't for the unfortunate design. I keep installing it and trying to adjust because it's a diamond in the rough, but I just cannot get past it. Gonna keep checking and hoping it all gets simpler, cleaner and more streamlined. Until then, Kindara and OvuView are the best compromises for me.

    It's really easy to use NFP and keep track of my cycles with this app. In fact, I'm no big fan of the app's design, but neither is this what matters most in birth control. (I really like OvuView's bright and clean design, however, this app doesn't allow using NFP.) I have a couple of wishes that would make the app even more useful to me. - display of number of cycle day in calender and form - display of temperature measurement time in cycle sheet - clicking on temperature dots in cycle sheet to automatically open the form of that particular day - display of menu when clicking the 3 stripes instead of automatically going back to "home view" - I have a bug where sometimes temperature disturbance factors are selected and displayed automatically; one factor I've added manually is usually selected but not ticked in the variable list, so that I have to tick and un-tick it so that it's not selected anymore One thing I haven't figured out yet is how to use the correlation display (which I can't wait to check) - maybe there's just not enough data yet/too many missing values? Also, I can't select variables in the analysis sheet - how do I do that?

    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!!!!
