Finding the best period tracker app for teenage girls can be surprisingly difficult!
Most period apps focus on fertility, pregnancy and hormones that simply aren’t as relevant for 11 to 18-year-olds.
Pre-teens and teens need something different: an app that explains their body clearly as it goes through changes, tracks their cycle in a way they understand, and answers the questions they may be too embarrassed to ask you.
That’s where luna comes in – the first ever and largest period and wellbeing app built from the ground up specifically for teens, with safeguarding at its core and medical experts behind everything.
Here’s why luna is the best choice for teens starting or navigating their cycle.
Why teens need a period tracker designed specifically for their age
Most mainstream period tracker apps assume the user is trying to conceive, has decades of cycle data to look back on or wants ovulation predictions.
Teenagers? Not so much.
Teens are dealing with: irregular periods, puberty changes, body image struggles, new emotions, unpredictable moods and often, a whole lot of confusion.
A teen-first period tracker needs to explain things gently, remove shame and give them a safe place to learn about themselves and build patterns over time.
luna does exactly that – all in a tone and style teens actually like.
What makes luna the best period tracker app for teenage girls
luna focuses on puberty, hormones and teen health – not adult fertility
Open any adult period tracker and within seconds you’ll find references to “fertile windows” and “ovulation scoring.”
These features are usually irrelevant (and often inappropriate) for pre-teens and teens.
luna focuses on what teens really need: what’s normal during puberty, why moods shift, what cramps and discharge mean, how hormones affect skin, how to prepare for their period and so much more!
It’s accurate, teen-appropriate, and never overwhelming!
luna gives teens a full wellbeing tracker, not just a period calendar
luna’s tracker gives teens everything they need to manage their period: a cycle calendar, symptoms, moods, physical changes and daily wellbeing logs.
As a result, it’s even suitable for pre-teens or teens who haven’t yet started their periods, but would like to start tracking things like moods, skin changes and discharge.
This helps them spot patterns early – from energy dips to skin breakouts to emotional changes.
At the end of each month, teens even get a personalised wrap-up video of their logs and suggested content off the back of that.
luna premium adds even more teen-friendly tools into the tracker itself, like Rate My Day and a custom avatar, making tracking more engaging (because teens love anything customisable).
luna offers anonymous expert support
Teens often have dozens of health and wellbeing questions…and zero desire to ask a parent or teacher.
In fact, in a luna poll over 2 in 5 teen girls (41%) told us they’ve used AI to ask for health advice!
And in another luna poll we learnt that more teen girls turn to Google or TikTok (31%) than to doctors (2%) for health and wellbeing help.
luna fixes that by offering teens anonymous access to real medical experts who verify the advice they’re given.
Access to luna premium gives your teen unlimited anonymous questions.
This means no more “I Googled my symptoms and now I’m panicking,” and no misinformation from TikTok or AI!
Teens a part of a safe community
luna is NOT a social media platform – teens cannot talk to each other, and that’s to keep everyone safe.
But we understand that a sense of community can also help teens feel like what they’re going through is normal, and make them feel less alone.
So all anonymous questions that are asked by others can be read through in a feed – access is tailored based on age, too!
By reading these questions, teens on luna quickly learn they aren’t alone, and that their worries are completely normal.
Expert health content teens can trust
luna’s educational content library is entirely reviewed by GPs, dermatologists, mental health experts, adolescent specialists and designated safeguarding leads.
Topics cover the full spectrum of growing up: periods, hormones, sleep, anxiety, body image, acne, relationships, puberty changes and more.
Free users get access to a limited number of articles, videos and quizzes. Premium unlocks the full library!
luna is built with safeguarding and safety from the ground up
Unlike adult apps that rely on ads or data collection, luna is designed for under-18s.
That means: no ads, no data selling, no private messaging, no unsafe content, all questions moderated, all answers reviewed, everything age-appropriate.
Whether on free or Premium, safety never changes – and that’s one of the main reasons parents trust luna over any other period tracker.
Teens actually enjoy using luna (which means they stick with it)
It sounds simple, but it matters: teens only use an app consistently if they actually like it.
The whole point of period tracking is to do it consistently and make it a habit, so wanting to come back to a tracker matters!
luna’s design, imagery, features and tone are all co-created with teen ambassadors and inspired by what our teen members have fed back to us.
It’s all about making sure the experience feels friendly, comforting and relatable.
This also makes Premium an easy purchase for many parents – because they know that it won’t be a waste when their teen loves using a tool that’s improving their health and wellbeing.
