Every woman deserves to understand her own body
Privately. Accurately. In her own language. On her own terms.
The Truth
Most period apps weren't built for you
80%+
of women don't have a 28-day cycle
Yet almost every period app on the market assumes you do. When your prediction is wrong month after month, it's not your body that's broken β it's the app.
900M+
women track periods on apps that sell their data
Your most intimate health information β when you bleed, when you're fertile, whether you might be pregnant β shouldn't be a product sold to advertisers.
7,000+
languages exist, yet most health apps speak only English
A woman searching for answers about her late period at 2am shouldn't have to translate medical terms from a language she barely reads.
1 in 5
women live with a disability
Most health apps are designed for sighted, hearing, neurotypical users. The rest are told to adapt. We believe the technology should adapt to them.
What We're Building
Cyra is the companion every woman deserves
Not a calculator. Not a calendar. A private, intelligent health companion that learns your unique rhythm.
Real AI, Not Math
Most apps use a simple formula: last period + 28 days. Cyra uses machine learning that studies YOUR history β every early period, every late period, every irregularity. It learns your pattern, not the textbook's.
Your Privacy, Always
100% offline. Data never leaves your phone. No accounts required. No tracking. Biometric lock keeps your information safe. Your body is not a data product.
Every Language, Every Woman
English, Hindi, French, Spanish, Portuguese, Arabic, Kinyarwanda. Health answers in YOUR language β not medical jargon you have to translate at 2am when you're worried.
Designed for Every Ability
Voice input. Screen reader support. High contrast. Large touch targets. Cyra is built so that every woman β regardless of vision, hearing, motor, or cognitive ability β can access her health information with dignity.
For Every Woman
She is why we build
The teenager who has nobody to ask
She got her first period. Her mother doesn't talk about it. Her school doesn't teach it. Her friends repeat myths. She's confused, maybe scared, maybe ashamed. She needs a private, trustworthy, judgment-free companion who speaks her language.
The woman whose app says she's "irregular"
She's been told for years that her cycle is wrong because it doesn't match 28 days. What that really means is the app was built for someone else, and pretended she was the default. She needs technology that learns HER rhythm.
The woman searching for answers at 2am
She's worried. Her period is late. She's searching online in a language that isn't hers, trying to understand medical terms, hoping the answer is "it's normal." She deserves reassurance in her own language.
The woman the tech industry forgot
She has a visual impairment, or a motor disability, or she processes information differently. Most health apps weren't designed with her in mind. She was told to adapt. We believe the technology should adapt to her.
Our Promise
What we will never do
What We Will Always Do
A LETTER FROM OUR FOUNDER
We're building Cyra in public.
Cyra has zero users today. I want to be honest about that before you read anything else on this site.
I'm Christian. I'm 23. I'm building Cyra from Kigali, Rwanda, because the women I grew up around β my mother, my sisters, my friends β were told for years by every period app they tried that their cycles were 'irregular.' What that really meant was: the apps were built for someone else, and pretended she was the default.
Cyra is being built for the 80%+ of women whose cycles don't follow the 28-day textbook. We use real machine learning that learns YOUR pattern. We let you upload photos of your old period records so the app can build your prediction model from day one, even if you've never tracked digitally. And your data stays on your phone unless you choose otherwise. Cyra is also built so no woman is left out: fingerprint or Face ID login, voice chat so you can talk to Cyra instead of typing, and full screen-reader support β because women with disabilities have been ignored by almost every period app, and that ends here.
If you're a woman who has been quietly told by technology that your body is wrong β Cyra is for you. We're not there yet. We're building. Thank you for being early.
