5 Popular Fertility Monitors: Which One is Right for You?

This post contains affiliate links.  You can see my full disclosure here.

I don’t know about you, but I’m so grateful that we live in a time when we have so much technology to help us in our fertility journey.

Think about it… we are the first generation whose family-building efforts have been assisted by apps, monitors, home test kits, and reliable medical information online.

Lately I’ve seen lot of ads and reviews for different fertility monitors.  I wondered if they’re really worth the extra money.  (After all, those trusty Wondfos and other basic ovulation test strips are pretty cheap). What makes them so special and what differentiates one from the other?

So I decided to do a comparison of five of the most popular fertility monitors and share them here with you.  I hope you find it helpful if you’re interested using one.

Ovusense Real Time Fertility Monitor


The Ovusense overnight monitor is worn internally (yes, up there).  It claims to provide a day’s notice of ovulation in real-time and a 4-day ovulation window with 99% accuracy.  It syncs with your iPhone or Android and is recommended for women with PCOS.  It requires a subscription (there are several different price points) and is approved for sale by the FDA*  in the United States.  If you want a detailed review, check out my friend Elisha’s hilarious (and informative) review.

Available on Ovusense’s website.  Use discount code FERTILITY25% for 25% off.   Also available on Amazon.  

OvaCue Mobile Fertility Monitor



Ovacue consists of an internal sensor (yup, another one you put up there) AND an oral/saliva sensor that you use each day, within the recommended 2-hour testing window.  It syncs up with an app you can use on your iOS device (or select Android devices) it and will store your cycle information for up to four months.  It does not require any subscription fees or test strips, so it saves you money in the long-run and it’s better for the environment.  It claims to predict ovulation up to 5-7 days in advance with 98% accuracy, and the manufacturers say it will work for women with irregular cycles and PCOS.  An added benefit is that OvaCue specialists at FairHaven Health are available to help you make sense of your results and charts.  How cool is that?!  If you want to see more pics, check out the brief review I did in 2015.

Check out the video below for more information on how OvaCue works.  You can also watch two video reviews (here and here).

ClearBlue Fertility Monitor

Unlike the other two monitors I’ve mentioned so far, the ClearBlue Fertility Monitor is a stand-alone model; it doesn’t sync with a mobile device. And for those of you who were turned off the by internal sensors of the other monitors, you’ll be happy to know the ClearBlue Fertility Monitor doesn’t require you to insert anything into your body! It reads urine test sticks (purchased separately) and detects both the LH and estrogen (it’s the only non-invasive monitor that does this) to help determine your 6-day fertile window. The touch-screen monitor stores up to 6 months of information and is appropriate for women with cycles of 21-42 days. It claims to be 99% accurate in predicting the LH surge (which is an indicator of ovulation).

Monitor and urine test sticks available on Amazon.  

Ava Ovulation Tracking Bracelet 


The Ava is definitely unique in that it’s a bracelet!  If you’re someone who might have trouble remembering to test at a certain time and doesn’t want anything to do with pee sticks or internal sensors, the Ava might be an option for you.  You wear it at night and sync it with your iPhone or Android in the morning.  It claims to use your resting pulse rate, along with some other physiological indicators, to determine your 5-day fertile window with 89% accuracy.  This FDA-registered* device also tracks your sleep and stress levels.  The Ava is best for women with regular cycles between 24-35 days, and it has not been tested for women with PCOS.

Bracelet available on AvaWomen.  

KNOWHEN Advanced Ovulation Kit


If the idea of spending over $100 on ovulation-tracking doesn’t sit well with you, the FDA-cleared* KNOWHEN Advanced Ovulation Kit might be a good “in-between” choice for you.  At a price range of $50-$75, it claims to pinpoint your 5-day fertile window with 98.9% accuracy.  It works by letting you look closer at a drop of saliva (almost like a microscope) first thing in the morning to determine your level of fertility.  It’s perfect for your inner science-geek!  No test strips or internal sensors required.


Available on KNOWHEN’s website  and Amazon.

Naula: A New Fertility Treatment Tracker App

Note:  This is NOT a sponsored post. I was NOT compensated for this post and I purchased Naula with my own money. I just really believe this app will be helpful to many readers and wanted to share it with you. This post does contain iTunes affiliate links, which means that I make a few pennies if you purchase this app after clicking on one of my links. You can see my full disclosure here.


When I was getting ready to do my IVF cycles in 2014 and 2015, one of the first things I did was search for an IVF app for my phone. I loved using Fertility Friend while trying to conceive naturally, but it didn’t work for me when I transitioned to treatments. I remember feeling so frustrated that I couldn’t find anything to help me track my IVF cycle.

A few weeks ago, I was browsing Facebook and I saw a post about Naula, a new IVF tracker app! (It can also track IUIs, egg donation, egg freezing, surrogacy, and FET cycles). I was intrigued by the screenshots in the iTunes store, so I sent an email through Naula’s website and received a lovely response from the creator, Paula, the next day. She was kind enough to chat with me for a few minutes on the phone and tell me more!

Paula created Naula because just like me, she was frustrated when she couldn’t find an app during her own IVF treatments. She wanted to create something that would let fertility patients keep track of their medications and appointments all in one spot.

Here’s How It Works

First, you add your treatment dates and details. Naula has pre-set options for the most common medications and appointment types, but you can also add your own. You can also add appointment locations and phone numbers, too. It’s okay if you don’t know all your appointment dates and medications at the start of your cycle. You can add them as you go, and you can always go back and make changes.


The beauty of the app is that each day it generates a calendar of all your appointments, tests, and medications. It lists them in the order you need to do them and will give you reminders if you want. So you can just check them off throughout the day and not worry about forgetting or getting confused.

It also has videos and instructions on how to administer medications. This is very helpful, especially at the beginning of the cycle when you’re still getting used to it.

Check out the video for more details!

My Thoughts

Since I’m not currently going through a treatment cycle, I haven’t been able to put the app to a true test. But I’ve been playing with it for awhile, and I like what I see.

No app is perfect, of course. I wish Naula had the ability to record blood test results and egg retrieval results. I guess it could be recorded in the “notes” section for those appointments, but it would be nice to have a specific place for those. Also, I think it would be really useful if Naula would let you record past treatments. I really wanted to enter my details from my previous cycles, but it wouldn’t let me create start dates more than a few weeks ago. (It will, however, keep your entries from treatments after you have finished that cycle).

Overall, I think Naula is a HUGE step forward for iPhone / iPad users who want to keep track of their fertility treatments. (Sorry, Android users, it’s only available on iOS). I’m definitely planning on using it when we do a FET cycle later this year, and will probably do an update on how the app performs for me then.

Naula has been selling for $19.99, but it’s currently on-sale for $5.99. If fertility treatments are in your future, I think it would be well worth your money to buy it now!

OvaCue Mobile Fertility Monitor Review

This post contains affiliate links.  I was not paid for this post, but I did receive a free OvaCue Mobile Fertility Monitor and pre-natal vitamins in exchange for my honest opinion.


Last month I received an email from FairHaven Health with an offer to test out some of their products.  I let them know that I was getting ready to start another round of IVF so I wasn’t trying to conceive naturally, but they generously sent me some products anyways.

Three years of TTC have made me very familiar with a basal body thermometer, but I had never tried any other sort of monitoring on my own.  So, I was intrigued when they sent me the OvaCue Mobile Fertility Monitor.   Continue reading “OvaCue Mobile Fertility Monitor Review”
