★★★★★ I set it to remind me every 21 days. Did not work. Would only recognize every 28 days. Reminding me of the correct day is it's only function and it cannot do that? Pretty bad!
★★★★★ I loved the app and it worked perfectly for months. It doesnt have a lot of fancy features which I love because I just need it to remind me to remove my Nuvaring and it stopped reminding me and Ive checked several…

★★★★★ Horrible, you have to pay to even change the time of your alarm!
★★★★★ I understand that the developers need to eat (get paid) but I would've definitely been more willing to buy the app if I would've just been offered the paid version upfront instead of being lured into downloading it and…
★★★★★ I tried to change the time but was told I have to pay to change it.

★★★★★ I take my pills late in the day and the app only notifies me at 9:00am. I tried to change the time but was told I have to pay to change it. This is bs, I should not have to pay $2 to set a proper time for my alarm.
★★★★★ App is very easy to use and I like the look of it, but there have been multiple days when my reminder hasn't gone off!
Nothing stands out.

★★★★★ Really easy and simple to use.
★★★★★ Would be great if that was addressed but other than that it's great and simple.
★★★★★ While other apps like these are super complicated to understand and work around with this app is simple and useful to remind me to take my bc.

★★★★★ While other apps like these are super complicated to understand and work around with this app is simple and useful to remind me to take my bc.
★★★★★ I love this app because of how easy it is and never fails to remind me daily! The kalender also tells you monthly when your placebo week is so you can even plan your vacation weeks or months before so you know when…

Straightforward app. I’ve never missed a day of birth control thanks to it!
Horrible, you have to pay to even change the time of your alarm! At this point, just use your built in calendar.
Has been a lifesaver. Has kept me consistent on changing my patch on time to void any unplanned pregnancy. Gives me a peace of mind.
I swear this app requires updates once a month (I don’t get it, it’s a single-task calendar? Like my bank app only needs updates a few times a year, what is causing this to require such constant revision?) and kind of fails to serve its purpose if you don’t have auto-update for your apps. I’m usually reminding myself to update the app so that it updates me on what I already know and am now late on!
Just makes it so easier, better than my period tracker app at sending notifications.
Awesome
