TAKE BACK CONTROL OF YOUR FERTILITY: OvuSense™ is an extremely accurate cycle monitoring system, unlike any other fertility tracker on the market. OvuSense can predict ovulation up to a day in advance, in real time, and detects the exact date of ovulation with clinically proven 99% accuracy.
“I have been trying to conceive for five years. I signed up for the OvuSense App User Study when I saw they were looking for participants. Last month, I had my blood drawn to confirm ovulation, and the Doctor said I did not ovulate for the month of May. However, OvuSense said I did. My husband and I had sex all around the time OvuSense said I was in my ovulation window, and I woke up to...a positive pregnancy test. I’m so happy!” Courtney, 2016

“I want to express how horrible ovulation predictor kits are for women with PCOS. I never had a positive or even close to one in all the months I used them. OvuSense confirmed ovulation on Wednesday Feb. 24th 2016 and I’m now pregnant! This OvuSense machine is amazing!! If you are considering buying…do it. So worth the money.” Eden Nicole, 2016

“I am pregnant after using OvuSense for two months. We were trying for 8+ years before that.” Kirsty, 2015

“OvuSense confirmed my exact ovulation date. I was amazed how late it was in my cycle! I had no idea how late I ovulated and I would have never guessed on my own. I knew that I might not ovulate every month, but at least I knew that I had this month. I never would have of have known that, or ‘when’ it was, if I didn't have OvuSense!” Jenny, 2015

Amazing product, app, and company!

I am very pleased with my experience with OvuSense. I have unexplained infertility and have a history of very irregular cycles. While taking a break from medicated cycles, I decided to track my temperature with OvuSense. I have tried to measure BBT manually and with the Ava bracelet, but neither have worked for me in the past. OvuSense was the first product I saw that was marketed towards women with long/irregular cycles. My first cycle I started using it a few days after my period ended. To my surprise it still identified my ovulation date and I had a 28 day cycle! My next (current) cycle I ovulated later than the previous month. I ended up ovulating on cycle day 25 and OvuSense did not miss a beat. It successfully identified ovulation again!! This was especially exciting to me because I have never been able to confirm ovulation on my longer cycles. Honestly I wasn’t sure if I was ovulating at all. For me, this product has brought peace of mind. I put all my trust in this little guy. The updated app is user friendly and I haven’t had any issues connecting the device. Customer service has been amazing as well. 100% recommend!!

Game changer

Best investment we have yet to make on our fertility journey!! After a series of test revealed no abnormalities for my husband or myself, we felt lost and powerless. I decided to purchase OvuSense with the hope of gaining more insight on my cycles , ultimately empowering us to take back some control.
I travel a lot for work and have little consistency in my days, so traditional BBT monitoring is unreliable. Moreover, OPKs testing haven’t always correlated with other markers & therefor has made timing difficult. OvuSense has taught me so much valuable insight about my cycle and has also enabled our medical team to tailor testing based on my charts. I love the ease of using it and the real time, reliable information it provides me daily. The recent 2.0 upgrade allows you to input other relevant insights/events into the app, which is another feature I love. Lastly, the amazing customer service and support from a large network of other women using the device make you feel like your not alone on this journey. Thank you OvuSense for helping us take back control of our fertility!

Amazing! Amazing! Amazing!

I cannot recommend this app and product enough! I would not have my 2 year old daughter or be preparing for our second daughter without Ovusense! This is the only product on the market that has helped me accurately pinpoint ovulation! I have pcos and was told I do not ovulate at all. Turns out I do!!! Just not when my doctors thought I should. They’ve always treated me like a woman that has a normal 28 day cycle/period when I don’t! Clearly I don’t when I can go months without a period. I had blood tests done at the wrong time because my doctors just didn’t understand. Ovusense taught me what I needed to know about my own body, my own cycles, and gave me back the control of TTC! It is amazing and so worth it! Customer support is always super and amazing! They show that they care and truly want to see all their users achieve their pregnancy dreams! ⭐️ ⭐️ ⭐️ ⭐️ ⭐️
