Ava Fertility Tracker: Features

What Does Ava Track?

Find Your Ovulation Period

You don't need to fuss with ovulation test strips first thing in the morning. You only need to wear the Ava bracelet on your wrist at night while you sleep and then sync it with the Ava mobile app in the morning to get a detailed analysis of what's happening in your body.

Ava monitors changes in your temperature, heart rate, breathing rate, pulse rate, and the finer details of your sleeping patterns. The idea is that all these physiological variables can predict your peak fertility window more accurately.

The user interface is well designed, so interpreting the data is rather easy.

Track Your Breathing Rate

Before menstruation, a woman's breathing rate ranges between 10-25 bpm. Many medical professionals use the breathing rate to measure physiological stress. A lower rate of breathing on Ava signifies a reduced state of stress. Several studies have shown that the breathing rate is lower in the follicular phase (from the first day of your period until ovulation). Knowing when this happens could increase your chances of conceiving.

Measure Your Sleep Rate

With the Ava Bracelet, you can keep track of your sleeping patterns. It not only measures how much sleep you're getting but also the quality of your sleep. These are important parameters that you want to track to predict your fertility window.

Measure Your Skin Temperature

To identify fertility phases better, Ava measures your skin temperature. Why is this important, you ask? After ovulation, the skin temperature increases by 1.5 degrees and remains high until the next menstrual cycle. The device carefully monitors and records the incremental shifts in your skin's temperature, alerting you to your ideal fertile window.

This is a much more accurate and convenient way to keep track of temperature changes in your body and eliminates the chore of having to take your temperature right when you wake up.

Ava Fertility Tracker also tracks your bioimpedance and perfusion movements - factors that also change with your menstrual cycle.

How Do You Use Ava?

The Ava bracelet is made of soft silicone and comfortable to wear all night, plus it comes in attractive colors. The sensor flashes a green light when it touches your skin, letting you know that it is working. You need to sleep at least four hours to allow the Ava fertility bracelet to do its job. In the morning, open your Ava app on your phone to synchronize your data from the night before. All the data you need to accurately detect your most fertile days will be at your fingertips.

Is Ava FDA Approved?

Ava is the only FDA-approved fertility tracker, which means no prescription is needed from a health provider to buy Ava. This fertility tracker has been tested by rigorous clinical trials , and its makers claim that the algorithm can detect your fertile window with 90% accuracy.

Is Ava Worth Trying?

Unlike LH tests that only predicts one or two days of your ovulation period or period tracking apps that provide inaccurate data, Ava is the most comprehensive solution to learn about your body insights while you sleep.

Although Ava carries a heavy price tag, it is still a reliable and accurate tracking device to eliminate the stress and uncertainty of figuring out your best time to conceive.

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.

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%.
