Bellabeat Leaf Tracker – Is It Worth it?

There’s a good reason why the fertility tracking industry in the wearable tech is expanding rapidly.

We are increasingly feeling the need to have a better understanding of our own bodies with respect to everything, including fitness, nutrition, chronic disease, and reproduction.

It therefore comes as no surprise that fertility-awareness-based methods and fertility technology are mirroring this trend. Now, even smart jewelry such as the Bellabeat Leaf Tracker can help women track their fertility.

How Does Bellabeat Leaf Compare with Other Fertility Trackers?

I have used quite a handful of fertility trackers and reviewed some of them here: Ava bracelet, OvaCue, Clearblue Fertility Monitor, and Generation Guard, etc.

Each of these tools has something to offer, and if you’re wondering whether Bellabeat Leaf might be right for you, it is worth taking a look at what it can offer.

What You Need to Know about Bellabeat Leaf

Leaf Urban Rose Gold Edition

This leaf-shaped accessory was designed to track your activity (steps and distance moved), calories burned, sleep pattern, stress levels, and monthly cycles.

However, this post will focus mostly on how the Leaf can help you track your overall reproductive health.

The video below gives you an overview of the Leaf, including how you can wear it.

Period Tracking

After purchasing the Leaf, you have to download the Bellabeat app (download link for iOS and Android). When you log into the app, a period tracking ribbon will be visible on the apps’ home screen.

You can choose not to have your period tracked or enter the data about your last menses, duration of menstruation and cycle length.

After entering the data, your cycle will displayed as a circle, with different colors representing a specific phase of your cycle.

Red drops will denote days that you have your period, purple stars will indicate your fertile days, and a purple oval will indicate when you’ll most likely ovulate.

The app can help you determine your fertile period and when you’ll most likely have your next period. You can determine this by sliding your finger across the circle to see these dates.

To log your period, you have to press the “Start date of last period” on cycle day 1 and “Period last day” on the last day of your period.

It is possible to change the last day of your period by pressing the “Extend period” button if you continue bleeding after entering the last day of your period.

Fertility Tracking

The manufacturer claims the Leaf is accurate and can be used by women with regular or irregular cycles. Actually, the Leaf calculates your fertile days based on the input data.

According to the manufacturer, the app grows smarter as you input data during every cycle, giving you customized advise specifically meant for you.

Sleep Quality

Poor sleep is increasingly recognized as a determinant of a woman’s reproductive health. Although little is known about whether sleep quantity and quality can affect fertility, some researches point to a possible association between melatonin, a key circadian hormone, and fertility.

The Leaf can compute sleep quality metrics such as total hours in bed, total sleep time, and movements during sleep. It can then tell you whether you’ve had enough sleep or not.

Some women have reported difficulties getting the Leaf into sleep mode, especially when it is worn as a bracelet. However, others have reported being able to obtain more accurate data by clipping the Leaf to their sleepwear.


This is another factor that has been associated with conception, with high levels of stress being associated with a delay in conception.

The Leaf was also designed to help women manage stress and offers exercises that can help relieve stress.

Bellabeat Leaf versus OvaCue

Appearance and Build:

When it comes to build quality, both products are winners. If you fancy design, the Leaf wins in terms of appearance in that you can carry this beautiful piece of jewelry around and no one can tell that it’s a smart device to help track your reproductive health.

In fact, many people will simply think you’re wearing a beautiful piece of jewelry. On the other hand, who cares whether you’re tracking your fertility except you and your spouse?

You don’t need to carry OvaCue with you all day long for it to effectively track your fertile days.

Fertility Tracking:

OvaCue is the winner. The oral sensor can measure the electrolyte resistance in your saliva and determine low and high (peak) fertile days.

The vaginal sensor can measure changes in the reproductive hormones estrogen and progesterone to confirm ovulation.

On the contrary, the Bellabeat Leaf is more of a calculator that uses data that you enter to predict your fertile days, which is not a selling point for this purpose.

Bellabeat Leaf versus Ava Bracelet

Appearance and Build:

These two products diverge in terms of design. The Leaf is definitely functional piece of jewelry that many fashionable women pick it over Ava.

In addition to wearing it as a bracelet, you can wear it as a pendant or brooch. Both Leaf Urban and Nature come in rose gold and silver editions, giving you the option of choosing your preferred design and color. Additionally, the Leaf comes with a leather bracelet and a necklace chain.

Ava comes in one color only; however, I doubt many women would care about this detail because Ava is worn only at night. Ava’s strap feels soft and is made of biocompatible silicone.

A few women have reported getting rashes around their wrists after using Ava; however, only very few individuals develop allergies to silicone, which is considered one of the most inert materials in the world.

Another winning point of the Leaf is that Bellabeat Urban is waterproof. It is sweat- and rainproof and can be worn in the shower or when doing the dishes.

However, the manufacturer warns that it can withstand water immersion for 30 minutes at a depth of one meter. Bellabeat Nature, on the other hand, is not water resistant.

Like Leaf Nature, Ava is not waterproof, and the manufacturer warns users to remove it before taking a shower or going for a swim.

Fertility Tracking:

Both devices collect several parameters that can help you track your reproductive health; however, the Ava bracelet is an incredible fertility tracking device compared to the Leaf.

Everything is streamlined for fertility tracking with Ava, while the Bellabeat Leaf is cluttered and optimized as an “activity tracker” with additional features to help women track their reproductive health.

Ava tracks nine different physiological parameters and can effectively help women pinpoint their fertile days.


As far as fertility tracking is concerned, the Bellabeat Leaf Tracker is not among my favorites. While this smart jewelry is well designed and has other interesting features, the fact that it relies on the data entered by the user to calculate the fertile period doesn’t make it more accurate than other fertility tracking apps.

Additionally, it is very expensive and isn’t worth buying if you just wish to use it to track fertility. Otherwise, it is worth buying if you wish to track other health metrics.
