Okay but the functionality doesn’t work
I used this app the first time I got pregnant two years ago and had issues with the camera picking up the ovulation strips. Second time around, having the SAME issue repeatedly. Doesn’t matter how many times I try it. Super frustrating.
VERY ACCURATE!!!!
I had no idea how ovulation and stuff works everything was new to me and it was my first time. I purchased the kit from Walgreens. I was diagnosed with PCOS and was afraid of infertility. I used the ovulation for only one month and I was so very surprised how accurate this thing is that I thought it wasn’t accurate I have a hard time trusting things. Anyways had intercourse around the time the kit told me I was fertile and I got pregnant within a month on first try! I was so shocked thank you MODERN FERTILITY for making me be at peace!!! 🫶🏾💕
Glorified cycle tracker
This app is just a glorified cycle tracker. Anything that you want to see results wise opens your browser. Their contact page says they address concerns or inquiries in 5 days. VERY slow results processing and no updates on received/processing. The site shows “processing” from the time the test is ordered even if it hasn’t been sent yet. Awful service that has not improved since partnering with Ro. Won’t be ordering other tests and certainly won’t track since they operate so heavily in browser.
Worked in 2021. Now? Not so much
3-4 years ago I found app, and test kits, to be helpful, easy to use, and (as far as I could tell) accurate. I have been using it again for the last 3 months and found myself frustrated with the app being unable to “capture” the picture of my test strip (literally: never). Also, despite frequency of my testing, I never had a strip result in anything more than a “low” result… despite obvious physical indicators saying otherwise (I realize this could be user error, which is why it’s my 2nd reason).
This month I switched to a different brand/app and was able to see the nuances in, even just, a few hours of testing - plus this other brand’s app captured test result images so fast, with *zero* issues - AND test strips found my peak LH no problem (lined up with my biological indictors). That is what I have been looking for, and wish Modern Fertility could still do.
All this to say: other features of the Modern Fertility app work nicely but, because of the reasons above, I’ll be moving on.
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!
5 star review
This app is truly amazing it helps tracks and calculates everything all you have to do is enter the information. If your looking to get pregnant or wondering like me if you are pregnant this app is for you.
Terrible!!
So unbelievably inaccurate. I would not recommend this kit if you are trying for pregnancy.
The strips don’t match the blood work that my doctor office is using when measuring LH. Same test at home and in the office are yielding drastically different results. Even to test in one day are yielding dramatically different results.
Photos Don’t Work Well
I’ve only been using the app for a few days but when I try to take photos of my OP test, the app never gives me a number that matches the test. The test will look dark enough to match the “high” level on the packaging but the app will give me a “low” designation 0-15. I end up putting it in manually
Can this be synched with Apple Health?
Would be amazing if it could sync with Apple health to pull all previous cycle history
