Technical questions about OvuSense Sensor and App

    Is my mobile phone or tablet compatible with the OvuSense App?

    The OvuSense App is available for Android and Apple devices.

    The OvuSense App is compatible with Android devices that have built in NFC (near field communication). However, please note that the OvuSense App is not compatible the Samsung Ultra series and Huawei phones.

    For Apple devices, the OvuSense App is compatible with iPhone: 7, X and later models with built in NFC running iOS version 8 or later.

    What is the difference between a realtime prediction and confirmation from the OvuSense App?

    OvuSense uses separate algorithm methods for predicting and confirming ovulation. By using data from the OvuCore Sensor, your OvuSense App is able to tell you in advance during your cycle that ovulation may be about to happen using the current cycle data - that's what we call 'realtime prediction' and it's not possible using any other app or monitor that uses temperature.

    Along with your prediction, your OvuSense App will show a green shaded area of your 'ovulation window' on your graph, with the predicted day of ovulation shaded as a blue vertical line. The ovulation window is the four days immediately around ovulation, from one day before until two days after ovulation.

    The OvuCore Sensor data is then used by the OvuSense App to confirm the exact date of ovulation - again no other app or monitor can do that. Although other apps or monitors may provide you with an ovulation date, clinical data show the confirmations are only based on a window during which ovulation is detected to have occurred.

    The prediction method using the OvuCore Sensor has a clinically proven sensitivity of 89% meaning that it picks up 89/100 ovulations in advance, but a positive predictive value of 96% which means that 96/100 predictions it makes are correct. Combining the data gives an overall accuracy figure of 89% [1]. The OvuSense App algorithm that interprets the OvuCore data was deliberately designed not to give you the false hope of an ovulation if it might be wrong and that’s why it misses out some ovulations, but is good at getting them right when it does show one. The prediction message appears up to one day in advance of ovulation.

    Confirmation of ovulation with the OvuCore Sensor has a sensitivity of 99% meaning it picks up all but 1 in every 100 ovulations, and a positive predictive value of 100% meaning it’s gets them all right. Combining the data gives an overall accuracy figure of 99% [1].

    The confirmation of ovulation message is displayed by your OvuSense App 2-5 days after you have ovulated, by which time it has much more data to make the calculations and that’s the reason why it’s able to pick up more ovulations, more accurately.

    [1] The accuracy of ovulation confirmation by OvuSense is based on the data set originally published at the 2013 ASRM meeting as a quality index: Papaioannou S, Aslam M (2013), and developed in the key publication outlining the accuracy, sensitivity and positive predictive value of advance prediction of ovulation shown at the 2014 ESHRE meeting: Papaioannou S, Delkos D, Pardey J (2014).

    Do I need to be connected to the internet to use my OvuSense App?

    No, your mobile device does not need to connect to internet for it to work and connect your Sensor. The OvuSense App will work offline for up to 30 days and you will receive warnings when you need to connect again to the internet to back up your data

    Beyond day 30 all your previous data will be retained by the OvuSense App but you will no longer be able to connect your OvuSense Sensor until you have connected to the internet again.

    I work shift hours, which means I have irregular sleep patterns, can I still use OvuSense?

    You can use OvuSense if you work shifts as long as you have a regular pattern of sleep during a week or more. The most important thing is to wear the OvuSense sensor for a minimum of 6 hours while you are at rest.

OvuCore Sensor questions

    How is the OvuCore Sensor cleaned?

    The OvuCore Sensor is designed with medical grade materials that prevent growth of bacteria. The OvuCore Sensor is cleaned on first use, and before or after each use by washing it with unscented and fragrance free soap in warm water.

    Do I take the OvuCore Sensor out to have sex?

    Yes. We recommend that the OvuCore Sensor is reinserted after sex, to increase the amount of data collected.

Payment

    What will happen to my data if I stop for a month or so, or all together?

    You can stop and restart your subscription at any time. You will be able to access all the data you download from your sensors, and all the other information you enter in the OvuSense App indefinitely.

    Can I share my sensor with a friend and can she carry on with subscriptions to save money?

    As a regulated medical device, the sensor is strictly for your personal use only. Sharing it with others may present a hygiene risk. Each sensor is uniquely registered to your OvuSense App account, so your friend will need to set up her own account and purchase her own sensor.

    Are there any guarantees with OvuSense, or money back offers, if I am not successful in getting pregnant?

    At OvuSense, we never promise ovulation or pregnancy. OvuSense offers you extremely accurate information about your cycles that you can ‘do’ something with, even if that information isn’t great news. OvuSense is the only fertility monitor that will tell you if you have, and have NOT, ovulated each cycle . Finding out you haven’t ovulated consistently isn’t great news and that’s why we created the ‘OvuSense Ovulation Promise’. If you use OvuSense for 90 days in a row and ovulation is not detected, we will offer you the option to switch to an alternate sensor, or a full refund to help you seek clinical advice and treatment if that's needed.

The OvuSense App and OvuSense Pro and data security

    I’m worried about my data getting leaked. How is it protected?

    At OvuSense data security is the highest priority, your data is stored in an encrypted format in the cloud meaning it secure and cannot be deciphered. The cloud database we use complies with strict regulatory guidelines which includes security management to the ISO 27001 standard and personal data protection to the ISO 27018 standard.

    Who can see my data besides me?

    The data can only be seen by the users you have chosen to share your data with and the OvuSense Technical Support team. If you contact us with a question, our support team may view your data if doing so is necessary to solve your problem.

    We keep your Personal Information confidential and generally do not disclose it. Please note that we would never sell your Personal Information to any third parties, nor would we share your information to social networks or other public places unless we have received prior consent from you.

Subscriptions

    Why do I need a subscription?

    A subscription is required to download and process your data from the sensor. While a subscription is valid you can continue to press ‘Connect’ and download data to your OvuSense App. You can cancel your OvuSense subscription at any time

    What happens if I cancel my subscription?

    After you cancel your subscription, it will remain valid until the end of the current 30 day billing period. At that point, you can continue to connect to your OvuSense Sensor for an additional 7 days ‘grace period’. Once cancelled, you cannot reactivate your old subscription. However, you can simply purchase a new subscription from ovusense.com anytime you like and pick up using OvuSense where you left off. If you purchase a new subscription within the ‘grace period’ you will not have any gaps on your graph.
