Illustrative conversations. Beta in development.

Life keeps moving, and Cyster keeps up.

Add context from the devices you choose to connect.

Notice what keeps showing up.

Tell Cyster about a late period, a rough night, or a change in your skin, and it surfaces the connections worth a closer look.

  • Share a detail instead of filling out a form
  • Check in on how you’re feeling
  • See what’s repeating and what’s still unclear

I’m thinking about fertility
My result was called “normal” 🤷‍♀️
The hair growth is getting worse
I started a new treatment 💊

Keep up with your routine.

Tell Cyster what you want to remember and when. It follows up by text and keeps track when you reply.

  • Reminders for the routine you already follow
  • At a time you choose
  • A quick reply keeps your record up to date

Your iron reminder, as requested.

Make sense of your results.

Send a lab report or ask about a study. Cyster explains the unfamiliar terms, shows its sources, and helps you work out what to ask next.

  • Results explained in plain language
  • Research you can read for yourself
  • Questions to take to your clinician

bloodwork.pdfwhat does HbA1c mean?
It reflects your average blood sugar over about three months.
This one was drawn right before your metformin dose changed, so it may already look different. Worth asking your clinician if it’s due for a recheck.
is there a real link between PMOS and sleep apnea?
Frontiers in Endocrinology, 2025A meta-analysis found sleep apnea in about 37% of women with PMOS, versus 6% without it.

Go in with your questions ready.

Cyster pulls the changes you noticed and the questions you saved into a short brief before your appointment.

  • Your updates, gathered in one place
  • Review and choose what to share
  • A check-in after your appointment
