KNOWN is your smarter, science-backed cycle tracking app that actually *gets* your body. No more “why do I feel like this?”. Just clear answers, better decisions, and feeling in control again. KNOWN helps you move with your body, not against it. We transform self-understanding into shared connection, helping women, partners, and friends move through life together.
YOUR BODY, BUT WITH CONTEXT
KNOWN learns your patterns over time and turns them into daily insights. How you might feel, what to expect, and how to plan your day.
It’s like finally having the cheat code to your own body.
WORK WITH YOUR CYCLE, NOT AGAINST IT
Every phase (menstrual, follicular, ovulatory, and luteal) hits different. And now you’ll know how to move with it:
- When to push vs. when to rest for YOU specifically
- When your energy is high (and when it’s not)
- How to eat, train, and focus smarter
No more forcing the same routine every day.
BRING YOUR FRIENDS AND PARTNERS ON THE JOURNEY (ONLY IF YOU WANT TO)
Let your partner or close friends in on what’s going on to feel more supported throughout your cycle.
Less explaining, more being understood.
BUILT WITH PRIVACY IN MIND
Your data. Your body. Your rules.
We don’t sell your data. Ever.
You control what’s shared, and you can delete everything anytime.
TRACKING THAT DOESN’T FEEL LIKE A CHORE
Log symptoms, mood, and daily habits in seconds. No overwhelming inputs, just easy check-ins you’ll actually stick to.
Consistency feels easy.
IT GETS SMARTER WITH YOU
The more you log, the better it gets.
KNOWN picks up on your patterns and starts predicting what’s coming, before you even feel it.
WORKS WITH YOUR FAVORITE WEARABLES
Works with Apple Watch, WHOOP, Garmin, and Oura Ring to bring in sleep, activity, and recovery so your insights get even sharper.
Your cycle isn’t random. You just haven’t seen the pattern yet. Let KNOWN help you guess less, know more.
1. Signing in is now seamless. We completed major native OAuth integrations, so Google and Apple Sign-In are fully stabilized on iOS. Fewer taps, fewer hiccups.
2. Onboarding is easier and more protected. We built secure, user-id-based recovery flags to prevent duplicate profile states when logging in with social accounts, so your data stays exactly where it should be.
3. “Tips” got a redesign. The tab formerly known as Rituals is now Tips, with a vertical, stacked card-swipe interface that feels much more like scrolling on your favorite social media apps.
4. Symptom displays are now more descriptive. We’ve updated the Circle feed to show logged intensity levels for your symptoms, making communication with friends and partners more detailed.
5. Insights and patterns feel more seamless. We updated the patterns view to make it feel more intuitive to analyze your own cycle.
6. Logging is faster and covers more ground. We streamlined the logging experience and surfaced additional symptoms to track, so your data can get richer without taking up more of your time.
