When I was trying to get pregnant with my 3rd child I went with the dates this app predicted would be my fertile days. A month later I found out I was pregnant! After I had my daughter I deleted the app but not the account, so it kept predicting when my period & fertile days would be. Well my husband & I "slipped up" once after having my daughter, so I downloaded Lady Timer again just to see if it was one of my fertile days, & of course it was. I ended up pregnant again! I'm now using this app to AVOID pregnancy instead of deleting it. Def a must-have for women!

Great tracking app that saves data

I previously used a different cycle tracker app, & it lost all my data when the app upgraded. So frustrating! So when I found Ladytimer, I was skeptical it would be any more reliable. Turns out the past 3 or so years I’ve used it I’ve not been disappointed! Every time I switch phones, so a software upgrade, or the app updates, my data is still there to see!

Simple and straightforward

With my busy life sometimes the days and weeks seem to just blur together. It's so nice to have an app that helps me track my period so I can tell when my period will start or how long it's been since my last one. And I don't have to log in or wait on ads to finish to see the info I need!
