The 6 Best Period Tracker Apps for 2021

And why you need to download one asap.

by | Aug 10, 2021

Have you ever been at the doctors and asked, “When was the first day of your last period?” And all you can say is something generic like, “Hmmm, a few weeks ago.”

Period trackers can be seriously useful tools for not only being able to answer that question correctly, but for helping you to learn more about your body: how your menstrual cycle is playing out, when you’re at your most fertile and which hormones are dominant, when.

They also play a huge part now in the women’s sport area – with the ability to identify when, during your cycle, you are able to hit peak performance – more about that here.

Are period trackers 100% correct?

They should be—that is, if you’re a woman who has a regular ovulatory cycle and who habitually updates the app.

While each app is different, using their own algorithms, they basically depend on your accurate input of info so that they can best generate an estimated day of ovulation, a five-to-six day fertile window, and the date of your next period. The longer you’re tracking your cycle, the more data the app’s algorithm has to work with, and the more likely it is to be correct.

Flo

Probably the most popular of the lot, the Flo app is used by millions of users daily to record ovulation and period symptoms, turning their data into super useful graphs that show exactly what your body is doing and when.

The Flow Premium offering goes a step further and offers personalised insights on your cycle & symptoms, health reports for your doctor, and a bunch of content that will answer basically every question you have about periods and conception.

Our favourite part: The chat feature.

The price: Free standard, from $19.49/6 months for FloPremium

Period Diary

A lot more basic than the other apps, Period diary allows you to log your period and symptoms, and provides information on your fertile window and potential ovulation date. In saying that it does have a pill reminder which ensures that you will never forget a dose ever again. Pretty neat.

Ovia

If you’re looking to get pregnant, the Ovia app might be your best bet.

It’s technically a fertility tracker so it really excels in helping you chart your basal body temperature, cervical position, and cervical mucus. But, unlike a lot of other fertility trackers, it has the ability to chart your period, too, and gives you predictions about your menstruation or fertility based on the data you input.

Clue

Clue is your choice if you’re not about all the flowers and glitter and just want a sleek data-based app that looks at your whole body. You can keep track of your cycle, fertility, mood, skin condition, digestion and energy. You can even log information about your period flow, menstrual products used, headaches, breakouts and cervical fluid.

Our favourite part: the multitude of options you have for what you can track

The price: Free standard, USD $5/month for Clue Plus

My Calendar

What’s cool about My Calendar is that it also includes programming to track irregular periods (we’re talkin’ to the 30 percent of women who experience irregular periods!), weight, temperature, moods, and blood flow, as well as sends reminders about birth control. With the ability to hide ovulation, fertility, and intercourse related data, this period tracker also works perfectly for girls and teens, as well as women who aren’t sexually active or have a partner who cannot get them pregnant.

Our favourite part: allows you to be discrete

Me v PMDD

If you experience particularly troubling systems just before your period like extreme sadness, hopelessness, irritability or anger, this app is for you. While you should first and foremost check with your doctor and find the support you need, this app is a great supplement to track your symptoms and hormonal changes in a clear way. The app uses a scale to track your mood, emotions, and physical effects like nausea, low energy and acne.

Our favourite part: it’s specialised to PMDD

How To Track Your Menstrual Cycle

What’s an example of them being wrong?

Your period tracking app can be wrong if you’re a woman with an irregular or variable cycle. “For example, if your cycle ranges from 28 to 32 days in length, the ovulatory window shifts three to four days each month,” says Dr. Kudesia, a reproductive endocrinologist and clinical assistant professor of obstetrics and gynecology at Houston Methodist. “Though the app shouldn’t miss the entire fertile window, it may be unable to pinpoint the exact day of ovulation.” Similarly, if you have a cycle longer than 35 days, there is, in Dr. Kudesia’s words, “a substantial likelihood” that you’re not regularly ovulating, which the app may not flag as possibility.

Can they ever be used as a reliable method of contraception?

First off, know that no period tracker offers 100% – or even 99% – protection from pregnancy. Secondly, there is a difference between a certified medical contraceptive app and period trackers. While period trackers certainly can show you your fertile Windows and in effect you can avoid sex during those periods (though the ‘fertile window’ they give may not be fully accurate), they can’t stop you from having unprotected sex.

Thankfully, there are a bunch of period tracking apps available for download that make tracking your period really easy. From the paid to the freebies, check out our picks above.

8 Of The Best Exercise Shorts That Will Power You Through A Summer Of Movement

It’s official: Shorts Season is officially here. While lockdown has seen many of us realise that activewear is less something to be worn for a workout and more a uniform we choose to do any and all daily activities in, when the warmer temperatures roll around, that favourite pair of sweatpants and leggings sometimes don’t cut it. Sure, they might be a staple in any wardrobe, but the Aussie sun doesn’t listen to reason, no matter how comfortable or cute it might be. And when it comes to summer, working out in leggings can feel like being trapped in a sauna, the sweat pooling at your ankles and around the waistband – as well as those other areas we won’t mention here. 

But as we transition from leggings to shorts, it becomes clear pretty quickly that not all shorts are created equal, and certainly not all shorts are fit for a workout. Take it from us at Women’s Health HQ, we’ve been there, tried it and lived to see the consequences. From the shorts that look cute but ride up to show your undies on the run, to those that feel like being strapped into a harness that’s digging into your hip bones. Then there are the fabrics that can cause chafing – a big no – and those that basically shine a spotlight on any area you might be sweating. 

Thankfully, a number of brands are here to cater to your exercise needs with innovative materials, fabrics and sustainable options to see you through a summer of movement. Regardless of your workout preferences or daily activity, we’ve selected the best shorts that will ensure you feel good in your body, shorts that get you excited to embrace the day and attack it with energy, that make you want to get outside and enjoy the outdoors, whether it be walking, running, or socialising in the park. Here are our pick of the best bike shorts below. 

Nagnata

Uptown Biker, $240

What says summer more than a pop of orange and the sleek shape of these Nagnata biker shorts? With its mid-length and horizontal raised rib side detail, these are shorts you can wear both for a workout and out to meet the girls. Made in Australia with a technical knit fabrication, the double-layer jacquard provides gentle sculpting qualities for the body, making it an excellent choice for light to moderate fitness activities like yoga, pilates or barre.

New Balance

Q Speed Fuel Short, $70

We love the colour of these shorts from New Balance which are cut with a sleek, speedy look that also helps to elongate the legs. Featuring NB DRY moisture wicking fabric, these are the shorts you want for high intensity exercise or long runs, keeping you comfortable and dry. There’s also an interior brief for added comfort and a stash pocket to keep your essentials. 

All Access

Ultra High Rise Zip Front Biker Short, $78

Yes, the colour is amazing but the fit is equally sensational on these All Access shorts. For those who love a high-rise fit and wide waistband that holds you in at the waist, look no further. The sleek, shiny look offers mid-compression and the fabric is moisture-wicking, so you can stay comfortable even during your sweatiest workouts. 

Nike

Nike x Naomi Osaka Utility Short, $90

Few things are worse than heading out the door for a run and realising your shorts offer no pockets for those essentials you need. You’re left to hold your iPhone, keys, and anything else you might need in your sweaty palm. Thankfully, Naomi Osaka knows what we need when it comes to exercise shorts and these utility shorts from her collaboration with Nike offer all that and more with a relaxed fit and elastic waistband. 

Tracksmith

Session short Tights, $72

When it comes to bike shorts, you want to feel supported and held in but you also want to be able to breathe. These Tracksmith session short tights are exceptional in offering support while still ensuring comfort remains a priority. Forget about chafing, these shorts won’t ride up and down and the fabric offers more coverage and support against the body. 

Outdoor Voices

Relay 3” Short, $48

Who said summer shorts have to be boring? Outdoor Voices brings fashion-forward style and playfulness to their collections with fun prints and exciting colours. We love the relay 3” shorts for their ultralight, quick-drying fabric that also happens to be made from recycled polyester. But more importantly, we love the print and Poppy Swirl is as good as it gets. There’s even a hidden pocket for your valuables, too. 

Lululemon

Align High-Rise Short 6”, $69

If you’re familiar with the buttery-soft feel of Lululemon’s tights, you’ll want to get your hands on a pair of their shorts, too. Made with the same Nulu fabric that their tights are known for, these shorts feel weightless and super soft. They might be our go-to staple for any workout, but the feel is so second-skin that it’s hard to not wear them for every other activity, too. 

Spiritual Gangster

Seamless Biker Short, $112

These biker shorts from Spiritual Gangster move with you, thanks to a three-tiered compressive waistband that offers a flattering high waist that hugs you in all the right places, without proving constrictive. They offer medium compression but are built for all day comfort, and the colour is a true summer staple because, let’s face it, who doesn’t love tie-dye?
