The Best Period Tracking Apps for Young Girls

Parenting

October 14, 2026

Let’s talk about periods.

‍

This is Abby from the PYE team. We didn’t let Chris write this one, although I know that awkward topics are no big deal to him. We had an OB/GYN ask us about the best period-tracking apps that she could recommend to young patients. This isn’t the first time we’ve received this question.

‍

To begin, we were surprised at how much other baggage comes with some of the more popular period tracking apps. I guess it’s no surprise – if you’re tracking your period as an adult, then you’re probably also interested in sex and fertility. But then there were the chat features on these apps, and this is where it got really explicit. No surprise! Anonymous sharing is often raw and extreme.

‍

Please note: apps appear in alphabetical order, not ranked by our preference or endorsement.

‍

Clue:

‍

Where can you find it?

‍

Apple
Google Play
Apple Watch

‍

‍

Tracking options: This app is FULL of tracking options; some are free while others are premium, but all are visible. The tracking options include everything from bleeding to sex life, with endless detailed sub options listed, including energy, cravings, basal body temperature, birth control options, and much more.

‍

Pros: Written in a more medical/matter-of-fact way and no chat feature. You cannot create an account if you are younger than 13. If younger than 18, the app requires parent or guardian help for permission to use the Clue App and help set up privacy settings. However, this simply requires checking a box confirming you showed it to a parent or guardian. There is no verification.

‍

Cons: Each of the tracking options has an info button that explains what it is and why you want to track it. For example, The “Partying” option allows you to track alcohol, hangovers, cigarettes, and “big night.” The “Sex Life” option allows you to track protected/unprotected, sex toys, and more. They do have articles/tips within their “Content” section. Each category is full of articles, but most require a premium upgrade to access. However, all of the titles are visible, and they're mature. For example: Trying to Conceive (How to Use Ovulation Prediction Tests), Fertility (Can You Get Pregnant from Precum?), and LGBTQIA+ (The Science Behind Periods and Gender).

‍

Our Thoughts? Adults only. We like that there isn’t a chat feature; however, there is a lot of information teens aren't ready for.

‍

Flo:

‍

Where can you find it?

‍

‍

Tracking options: When creating an account, Flo asks you what you need the most help with: tracking my cycle, learning about my body, managing my symptoms, or understanding changes in my body. Similar to Clue, Flo offers multiple options for the user to track. These include mood, symptoms, discharge, digestion/stool, physical activity, and others (travel, stress, meditation, journaling, Kegel exercises, breathing exercises, and disease and injury).

‍

Pros: When creating an account, the app explicitly states that “due to COPPA requirements, all our users must be at least 13 years old. Due to GDPR requirements, all EU users must be at least 16 years old.” After this screen, Flo asks if you have discussed your period with an adult, such as a parent or teacher. Flo is full of insights and articles, but most require a premium upgrade to access. Flo requires a subscription; new users receive a 7-day free trial before being charged. The articles range from cycle phases to reproduction, nutrition, mental health, sexual wellness, and more. There is a lot of information for young women if they have questions but don’t have a trusted adult to talk to. One thing to note is that some of the articles available in the premium account may be information you aren’t ready for your child to have access to yet.

‍

Cons: The Secret Chats feature contains explicit content. Really extreme sexual fantasy stuff. It is a place where users can anonymously ask and answer questions. Just a quick scroll through this section revealed a lot of mature content. We found questions about skincare, and then questions about “booty calls,” sexual fantasies, sexting, oral sex, etc. The responses to some of the questions in the secret chat were very graphic and detailed. Flo has an AI Health Assistant for girls who have questions but no trusted adult to turn to.

‍

From a PYE follower:

“I checked my FLO app today, and it has horrible explicit things that are available right in the daily insights. This is a place in the app where you immediately look, and the daily insights are designed (programmed) for anyone and everyone to look at (think of Flo’s version of Instagram stories). The particular story I saw today said that it has “life-changing” tips for m*sturbation. Previously, I have been horrified by explicit things that I’ve incidentally come across in the secret chats of this app (in response to this, I decided to just avoid that component of the app), but the daily insights are right in your face. I can’t ignore it and will delete the app. I would strongly encourage all women (young or old) to not support this kind of app or company.”

‍

Our thoughts? This app is for adults. While Flo is chock full of information, it also means there is access to a lot of information your child isn’t ready for.

‍

Google Health:

‍

Where can you find it?

‍

‍

Tracking Options: This app used to be the Fitbit app. It allows you to track multiple areas of health. As far as menstrual cycles, the app tracks bleeding, symptoms, mood, protected or unprotected sex, ovulation test, fluids, and other events (the option given here is the morning-after pill).

‍

Pros: You can actually use the Google Health app without owning any additional device. The app allows you to track multiple areas of your health.

‍

Cons: This app has a community option where the user can join any of the community groups once an email has been verified. There are different topics for each group and even options to join groups of people who are near your location.

‍

Our thoughts? The Google Health menstrual cycle tracker seems pretty straightforward. We feel this app seems appropriate for an older teen, but we're always cautious about any "community" feature and the chat that comes with it.

‍

The iPhone Health App:

‍

Where can you find it?

‍

Apple
Apple Watch

‍

‍

Tracking options: This app tracks temperature, weight, symptoms, moods, sexual activity, ovulation, cervical mucus quality, medicine, progesterone, and flow. You can choose to add other factors such as pregnancy, lactation, and contraceptives. Each of these trackers can be toggled off.

‍

Pros: It’s already on the iPhone! Nothing extra to download.

‍

Cons: Not available on Google Play. No way to “lock” trackers in the toggle-off position.

‍

Our thoughts? We feel this app could be a reasonable option for a young girl, provided all extra tracking features are toggled off. However, there is no way to lock these features in the off position. Lastly, there are a few articles accessible within the app about the basics of fertility and ovulation, spotting, and factors that can impact a cycle.

‍

MagicGirl:

‍

Where can you find it?

‍

Tracking Options: This app tracks bleeding, mood, symptoms, diary notes, hygiene, weight, sleep, and exercise.

‍

Pros: There isn’t anything related to pregnancy or fertility on the premium version. The design is geared towards a younger audience and includes a video library of introductory period topics such as 10 Period Life Hacks, My First Period, and more. The premium version requires a one time payment and allows parental controls to be locked and removes ads.

‍

Cons: You have to pay to remove ads and lock the parental controls, which can turn off these features: intimacy, cervical fluid, ovulation test, pregnancy test, the pill, and chat. It contains access to Twitter, Facebook, and TikTok inside of the app. There is a chat feature that cannot be turned off unless paying for the premium version.

‍

Our thoughts? While we love the look of this app for young tweens, there are too many risks inside the app. The video content and graphics are geared toward younger users and won't appeal to older teens or adults, but the access to social media and the inability to turn off features like chat and ads make this app not worth the risk. This app could be useful if a parent wanted to use the video library as an aid in discussions with their tween.

‍

Period Tracker Period Calendar:

‍

Where can you find it?

‍

Tracking Options: In Teenager Mode, you can choose your goal for the app: track my period, try to conceive, track my pregnancy. In period tracking mode, it tracks: flow, medicine, physical symptoms, moods, energy, skin & hair, breast self-exam, and lifestyle. These tracking options can be turned off if desired, but can’t be locked off.

‍

Pros: This app has a “Teenager Mode” that can be turned on during set-up. This shows up as an option when entering the user's birth year. In “Teenager Mode,” there are mini-courses that cover appropriate topics for teens, such as: Tired All the Time on Your Period? Here’s Why, Period Acne? 4 Ways to Calm It, and Which Type of Headache is Hitting You?

‍

Cons: There are ads (mine was for Adobe Photoshop), but going premium removes ads. Sexual activity lists unprotected sex, protected sex, masturbation, and kissing. There is also a section to mark increased or decreased libido.

‍

Our Thoughts? This app looks fairly safe in “Teenager Mode” and would likely be appropriate for a high school student. We like that there isn’t any user-generated content and that there is an option to toggle off options you don’t want visible. However, those can’t be locked in place. The settings section also links to an external browser. The mini courses are nice for girls to learn more about their bodies, but we always believe that these topics are better addressed through conversations with trusted adults than through Google searches and period tracker apps, if possible.

‍

Stardust Period Tracker:

‍

Where can you find it?

‍

Tracking Options: This app has several tracking options: feelings, cravings, symptoms, fluids, gut health, physical connection/intimacy, flow, activities/exercise, cycle disruptors, birth control, medications, supplements, endometriosis, and even customized options that you create yourself.

‍

Pros: Tweens/teens often struggle to understand why their mood, skin, or energy changes drastically from week to week. Stardust provides clear, non-judgmental explanations linking emotions and cravings to specific hormonal shifts based on cycle phases. It reframes period tracking from a clinical, chore-like task into a fun, relatable experience, which makes it very popular with tweens/teens.

‍

Cons: Includes ovulation and fertility features, as well as content related to sex. Additionally, there are links to Instagram, TikTok, and a browser through the settings page of the app. We also don’t like the connection to horoscopes, which seems like an unnecessary nod toward astrology.

‍

Our thoughts? While Stardust's blend of science, horoscopes, moon phases, and zodiac alignment makes it appealing to teens, families who are uncomfortable with astrology-based content will want to steer clear. Privacy is an additional concern: independent audits found that the app begins tracking and sharing device identifiers and usage data with third-party analytics services the moment it is opened.‍

‍

Teen Cycle:

‍

Where can you find it?

‍

‍

Tracking options: This app is literally as basic as the name. It only tracks your period. You choose between normal flow and light flow. There is no tracking of ovulation or fertility.

‍

Pros: The most simplistic tracking app that only tracks your period - nothing else. No ovulation windows, no intimacy logging, no fertility content anywhere. It works completely offline. Privacy is where this app truly shines. There is no account, no server, and no data collection of any kind. Everything stays on the device.

‍

Cons: No true cons for this one. However, users should be aware that under settings, if you click “support,” it opens the company’s website in a web browser.

‍

Our Thoughts? We feel that this is the perfect app for tweens and teens. There are no bells and whistles with this one. There is often a free trail, followed by a one time payment required for this app.

‍

Concluding thoughts about our research.

‍

You’d think that finding an app appropriate for young girls who just want to track their periods would be easier than this, but it’s a good reminder to always check the apps your kids are using (7-day rule). Always check apps for chat features and mature content. User-generated content (i.e., chat) always increases the risk of inappropriate content.

‍

A period tracker app is a great tool to help your daughter understand her cycles (I wish I had these when I was younger!), but nothing beats a trusted adult to come to with embarrassing questions about how her body works and sexual health. We highly encourage you to make conversations about our bodies, sex, periods, and hygiene the norm with your daughter.
