Everything I needed

I waited about a year before leaving a review to make sure I was being accurate.
This offers simple and comprehensive tracking and amazingly accurate predictions. It is incredibly user-friendly, with a clean and intuitive interface that makes tracking my period a breeze. Logging my cycle data, including start and end dates, symptoms, and mood, is quick and simple, even on busy days. I've been consistently impressed by the accuracy of its cycle predictions. It learns from your input and provides personalized forecasts for your next period and ovulation window, helping you plan ahead with confidence. I appreciate the app's commitment to privacy and security. My data is encrypted and stored securely, giving me peace of mind knowing that my sensitive information is safe.
Overall, it has truly transformed the way I manage my menstrual cycle. It's reliable, easy to use, and packed with features that empower me to take control of my reproductive health. Whether you're trying to conceive, prevent pregnancy, or simply track your cycle. I am definitely not disappointed!

This app is buggy and customer service is non responsive

I have yet to have a good experience with Modern Fertility and I’m very confused as to why there’s so much hype around this brand. From the moment I ordered my fertility test I encountered issues. The first issue was the purchase confirmation email didnt include any details about what I ordered or paid. My employer reimburses employees for fertility treatments and such so I needed to be able to send them a receipt. When o reached out for support I was met with nothing but incompetence and it took weeks to get what I asked for, which was simple receipt! Now my order doesn’t even show up in my account and I didn’t bother following up about that because trying to get a response from someone takes so long that it’s not even worth the wait.

Another issue I’m having with the app is I wasn’t able to select the correct start date for my cycle because the calendar was cut off. I emailed and texted for assistance, asking them to adjust it, but it’s been nearly a week and no response. How am I to even rely on this app to accurately track my flow and other things when I’m not even able to enter in my data correctly? Also really annoying that it’s not adjustable in the app. I shouldn’t have to reach out about simple stuff like this. Overall I’m very underwhelmed with this brand and won’t buy anything else from them and I’m deleting this app.

Great idea, frustrating app

I love these ovulation tests and app. HOWEVER, when I go to log my LH surge , it is soooo annoying how I have to hold it steady and it keeps saying “perfect this will take a few seconds” then it’ll say “it’s too close” then “try holding it over the strip” THEN it’ll do that so many times!! Over and over! Also, it’ll give me 4 different numbers on one test back to back! I’m looking at a test now and the line is as dark, if not DARKER than the control line and it says it’s only 30 LH! HOW?!?! On the package it SHOULD BE 65+ ! That’s what I would manually log! Soooo how is this possible? Also, it is pretty accurate about the days I ovulate as well as when my LH will be most elevated! That’s impressive that it gives me that knowledge!
This company should sell vitamins to help men and women conceive! So, all in all, yes I love the product. The app is great. HOWEVER, It’s soooo frustrating and annoying to take the photo and it always takes at least 10 min for one!! And it’s super annoying it doesn’t give me accurate LH numbers! Other than that, it’s ok. If there was another company that does this same thing, I honestly probably would try their app and test. I hope the app gets fixed for all of this bc otherwise this would be wonderful. Good luck.
