Smart women's health assistant
Your cycle.
Finally explained.
Neia connects dates, symptoms and entries to show you what it knows, what it estimates and why.
No ads. No selling health data. No medical promises.
Inside Neia
Less noise. More understanding.
It all starts with a simple question: what do you need to know today? The app speaks English and Portuguese; the screens below are from the free version in Portuguese, with made-up data and a sample conversation.
Trust before certainty
A prediction is not a guess.
Neia shows real dates, estimated windows and confidence level separately. When you confirm a period or add an entry, the reading is recalibrated.
- Real
- What you logged.
- Estimated
- What the cycle suggests.
- Explained
- The data used in the reading.
Privacy without the small print
