  • 99% accurate in predicting your fertile window
  • Pre-programmed with a complex algorithm

Cons


  • Not 100% accurate as a means of birth control

  • Requires internet connection to access the app and sync data
  • Only records the first reading of the day. Mistakes can't be erased

Daysy Fertility Tracker Review: Pricing

There is an initial cost involved in buying the Daysy fertility tracker, which resembles a thermometer. There is also a monthly fee payable for the app. You are paying more for the fertility tracker than you would for a normal thermometer, however, Daysy's thermometer records your temperature to two decimal places rather than one. This accuracy makes a big difference when you are tracking daily basal body temperatures. Also, the fertility tracker is pre-programmed to sync to an app, removing all the guesswork and manual calculations that can result in errors.

Prices are as follows:

Daysy 2.0 - Your personal fertility tracker: 299 EUR

Daysy 2.0 & Period Repair Manual: 311 EUR

Daysy Fertility Tracker Review: Main Features

1. A precise temperature sensor Using the sensor, you will take your basal body temperature every morning as soon as you wake up. You will manually add your menstruation to the period tracker at the click of a button.

2. A self-learning, intelligent algorithm Based on a database of five million menstrual cycles, Daysy will get to know your cycle and, after two to four months, be able to predict to 99% accuracy when you are most fertile.

3. A precise tracking app Syncing your temperature sensor to the app on your mobile device means you don't have to guess where you are in your menstrual cycle because not all women ovulate at the same time every month.

The Daysy display makes use of different color dots to notify you where you are in your cycle. Daysy may even be able to detect pregnancy - but this should be confirmed with a pregnancy test.

Daysy Fertility Tracker Review: How to Use

The Daysy fertility tracker is easy to use:

  1. When you wake up, before you eat or drink anything, put the sensor under your tongue on the same side of your mouth every day.
  2. The sensor will 'beep' after about 60 seconds when it has recorded your temperature.
  3. Sync your sensor with the app on your mobile device.
  4. Daysy uses the recorded data to determine where you are in your menstrual cycle.

Knowing where you are in your cycle will make it easier for you to conceive - you will know to have intercourse when you are most fertile. Knowing when you are fertile can also work as a contraceptive if you are trying to avoid falling pregnant because you will know when to avoid intercourse. However, using Daysy as a contraceptive is not a 100% guarantee against pregnancy.

Daysy Fertility Tracker Review: Worth It?

Daysy is registered with the FDA as a fertility diagnostic proceptive, and not as a contraceptive. If you are looking for a safe, easy-to-use fertility tracker, then Daysy is worth your consideration. Rather than trying to guess when you are fertile, and to remove any errors associated with manually tracking your temperature with a normal thermometer, Daysy gives you peace of mind.

Daysy is safe to use and accurately predicts fertility 99% of the time.

How to Use OvuCore OvuCore consists of a data reader and a personal sensor. To use OvuCore, you need to enter the first day of your menstrual cycle into the reader as a "new cycle." You can use OvuCore the day after your bleeding ends. Place the sensor into your vagina overnight, where accurate temperature readings are taken every 5 minutes. In the morning, please the sensor on the reader and download the data. Once the reader confirms you are ovulating, you can stop using the sensor for the remainder of that cycle. Using OvuSense For Conceiving and Contraception The data from the sensors give you an accurate reading of when you will be most fertile. This can be used in cases where you are trying to conceive because OvuSense gives you a window where you are ovulating. However, OvuSense can also be used to avoid pregnancy where you stop sexual intercourse over the period where you're most fertile. Ovusense Fertility Monitor: Is It Safe? OvuSense is completely safe to use because no radio waves are transmitted from the sensor while applied to your body. OvuSense is FSA and HSA approved. Ovusense Fertility Monitor: How Accurate Is It? The main question is, "Does Ovusense really work?" OvuSense confirms ovulation by specifically looking for a continuous rise in your average core temperature. Generally, an increase of at least 0.3°C over three days indicates ovulation, although your unique pattern may vary. OvuSense claims its devices have a rate of 99% accuracy for ovulation detection, with its predictive abilities clocking in at 89% with a positive predictive rate of 96%.
