A smarter way to track ovulation.

Embry is a cycle tracking app for couples trying to conceive (TTC). It helps you understand your cycle and ovulation in real time and stay aligned with your partner on what to do next.

The TTC journey can feel uncertain, with so much out of your control, you're never quite sure if you're doing the right thing at the right time. Embry is built to reduce that uncertainty and share the mental load with your partner.

What makes Embry different

Real-time ovulation estimation

Surfacing real time ovulation insights as you enter new data.

Embry uses a Bayesian Inference model to estimate your ovulation. We are working on how to visualize the outputs of a model like this in a way that helps you understand how confident it is about its estimation.

What we're improvingHow do we make ovulation predictions easy to understand and trust as they update during your cycle?

Partner access

Building what “Partner mode” looks like.

Configuring secure backend connections between you and your partner — what they see, what they can log on your behalf, and how consent is granted, paused, and revoked. The shape of being in this together, without surveillance.

What we're improvingWhere does “informed” end and “overshared” begin?

Chat interface refinements

Continuously redesigning how Embry interacts with you.

Making Embry more safe, thoughtful, and sensitive to the TTC journey. Tone on a hard cycle day is a design decision — we're writing, testing, and revising it with you rather than guessing from outside.

What we're improvingWhat should Embry say, and what should it stay quiet about?

Privacy & security

Your privacy is a core priority — beta or not.

The protections that ship with v1 are the ones you get in the beta.

What's protected

Encryption
All data is encrypted in transit over HTTPS, and at rest with a key tied to your account.
Data minimum
We only collect what you choose to share. Nothing about your cycle is inferred from elsewhere on your device.
No tracking
No background tracking. The app runs only when open, and does nothing when it isn't.
Your data
You can clear local data from the app any time. Delete means deleted.
Beta access

Open the app. Add it to your home screen. Start tracking.

If you're already on the list, you'll be signed straight in. If not, you'll land on the waitlist — we onboard a new group every two weeks, but it might be sooner.
