Why Luna exists
Most apps give you dates. They don’t tell you what to do with them.
Most apps stop at dates
They tell you when your period might start. Not why you feel the way you do.
Too many cycle tips pretend to be exact
A precise date. A fixed ovulation day. A ready-made explanation. Real cycles are rarely that simple.
Wellness advice is often too vague
“Rest more.” “Eat better.” “Listen to your body.” Sounds good. Doesn’t help much when something is actually happening.
Luna helps you know what to do
It connects your symptoms, energy, and timing. And gives you guidance you can actually use.
What Luna helps you see
More than a tracker. Real guidance for your day.
Your cycle patterns
See what actually repeats, instead of relying on a single date.
Recurring symptoms
Anticipate them, instead of just dealing with them.
Energy and mood
Adjust your pace to what your body is going through.
Daily decisions
Know when to slow down, when to plan, and when to listen to yourself.
Useful guidance. Not fixed rules.
Wellness that adapts to you
Four daily cards, shaped by your real cycle
Symptoms
Guidance based on what you actually feel, not generic advice.
Energy
Know when to slow down, and when you have momentum.
Nutrition
Simple guidance for what to eat, based on your phase.
Mood
Make sense of how you feel, instead of it coming out of nowhere.
Useful guidance, adapted over time.
Ask Luna anything
Ask your questions. Luna answers with your cycle.
Is this normal before my period?
Based on your cycle, not on averages.
Why am I more tired this week?
Linked to what you’ve logged, and your patterns.
What should I do today?
Guidance adapted to your situation, not generic advice.
Luna doesn’t diagnose. It helps you navigate your day.
When your cycle stops feeling random
“I used to dread certain weeks without really knowing why. Once I could see the timing, it made more sense. Not fixed, but less confusing.”
“My symptoms felt completely disconnected from each other. Seeing them together in one place helped. I stopped thinking something was wrong.”
“I showed my partner the cycle view once. He got it faster than I expected. We argue less about timing now.”
“I used to feel anxious every month, like something was about to go wrong. I still have hard days, but they don't feel random anymore. That changed a lot.”
“I tried a few apps before and most felt like too much. This one is calmer. It just tracks what I need.”
“I mostly chose it because I didn't want my data shared. I didn't expect to use it this often. That surprised me.”
Understanding your cycle shouldn’t make things harder. It should make them simpler.
Privacy panel
Data stays yours
Partner guardrails
Shared guidance can help a partner understand your phase. Notes, intimacy, temperature, and raw symptoms stay private.
Account control
Delete account in one tap from Settings.
Privacy
Private by design, in ways you can actually check
Your cycle data stays yours.
What matters is easy to check: where your data is stored, how you delete it, and what your partner can’t see.
Partner sync, with boundaries
Helpful when you want support. Still private when you do not.
Share context. Not your journal.
Your partner never sees your notes, your intimacy, or sensitive data.
It’s built for support. Not for tracking you.
Partner sync
Helpful, not intrusive
Situation
Likely in the luteal phase. Energy may feel lower. More sensitivity would not be unusual today.
Who built Luna
We built Luna because we needed it.
We tried apps that record data. None of them helped us understand.
That’s why we built Luna. An app that helps you understand what’s happening, and what to do with it.

“As the partner, I didn’t want surveillance. I wanted context. Luna is the difference.”

FAQ
Frequently asked questions
Is period tracking data safe on a cycle app?
Yes. Hosted in Europe (Frankfurt). No data selling. Delete everything in one tap. No email. No waiting.
Can I share my cycle with my partner without sharing everything?
Yes. Your partner sees helpful context. Not your private data. You control everything.
Does a cycle tracking app work for irregular periods?
Yes. Luna adapts to your real cycle. Not a perfect model. It shows ranges when things are uncertain, not fake precision.
What is the difference between Luna, Flo, and Clue?
Flo and Clue are good at tracking. Luna helps you understand what’s happening, and what to do with it. Less tracking. More useful guidance.
