YOUR AI HEALTH COMPANION

More than an app.
Your health partner.

Stella is trained across the full spectrum of women's health — hormones, cycles, mood, sleep, nutrition, and more — and grounds every answer in your personal tracking data, not generic textbook averages.

Unlike generic health tools, Stella combines the world's leading women's health research with your personal health history, ensuring every answer is evidence-based and specific to you. Because Stella learns continuously from your evolving health data, guidance becomes more accurate and more personalized over time.

HOW STELLA WORKS

Not just answers.

The right answers,

for you,
right now.

Tracking one thing in isolation never tells the whole story, the full picture of your personal health data, and the ability to act on it- so every response is evidence-based specific to you, and built to move you forward.

01
Deep Knowledge

Research that goes
far beneath the surface.

Stella is built on the latest peer-reviewed women's health research — not surface-level information you can find anywhere. Every answer is grounded in how hormones shape your health.

No opportunity is wasted to help you understand 
why hormones matter and how to work with them.
02
PERSONAL CONTEXT

Answers built around
what you're experiencing.

Research only matters when it meets your reality. Stella integrates your cycles, hormones, symptoms, mood, and conditions into a picture that gets richer with every cycle — so every answer is specific to where you are right now. Not a generic response.

Stella’s
Superpowers

01

Cycle-Aware Responses

Every answer Stella gives is filtered through where you are in your cycle. Advice about sleep, exercise, or nutrition automatically accounts for your current hormonal phase and recent logged symptoms.

02

Pattern Recognition

Stella analyzes your historical data to identify meaningful patterns — recurring symptoms, mood shifts, sleep disruptions — and surfaces them proactively, not just when you ask.

03

Symptom Triage

When you describe a symptom, Stella helps you understand whether it's likely hormonal, lifestyle-related, or something worth discussing with a doctor — and helps you articulate it clearly.

04

Nutrition & Movement Guidance

Get phase-specific nutrition recommendations — iron-rich foods during menstruation, complex carbs during luteal — and movement suggestions tailored to your body's current energy reserves.

05

Hormone Education

Ask Stella to explain estrogen dominance, progesterone deficiency, PCOS, perimenopause, or any hormonal concept — and get clear, non-clinical explanations grounded in current research.

06

Doctor Visit Prep

Stella prepares a concise summary of your recent cycle data, notable symptoms, and pattern observations — formatted specifically to make your healthcare appointments more productive.

"Stella explained in one conversation what three doctors had failed to connect over two years. Suddenly my symptoms had a name, a pattern, and a plan.

Stella · Day 14 Insight

Hi Adriana! You're in your ovulation phase right now — estrogen is peaking, which usually means you're feeling sharper and more energetic than your cycle average. Is there something specific on your mind today?

I've been getting really bad headaches around this time every month. Is that related to my cycle?
S
Stella · Personalized Response

Yes — and your tracking data actually supports this. Looking at your last 4 cycles, I can see you've logged headaches on Days 13–15 each time. This pattern is consistent with "estrogen headaches" or ovulatory migraines, caused by the rapid estrogen surge right before the LH peak triggers ovulation.

This is genuinely common — about 20% of women experience hormonally-triggered headaches specifically around ovulation. A few things tend to help: staying well-hydrated in the days before Day 14, magnesium supplementation (some research supports 400mg/day), and reducing high-histamine foods around this time. Would you like me to add a reminder to your Day 11–13 notifications, or would it help to have a summary to share with your doctor?

Yes please — can you add the reminder and give me the summary?
S
Stella · Actions Completed

Done! I've set a gentle reminder for Days 11–13 to increase water intake, and I've prepared a 4-cycle symptom summary for your records — you can find it under Health Reports. Is there anything else you'd like to understand about what your body is doing this week?
