Sinoa started with a moment that's hard to forget.

A sudden cardiac episode. Alone in the back of an ambulance, not knowing what was happening, thinking about family and whether everything would be okay.

After that, the episodes didn't stop. But capturing them proved difficult, even with modern devices.

The data didn't always line up with what was being felt in the moment.

That gap between experience and data became the problem to solve.

Sinoa was built to help close it.

How Sinoa Works

Apple Watch (1-lead ECG)

KardiaMobile 6L / EMAY (6-lead)

Google Pixel Watch (with ECG app support)

Step 1

Capture a recording

Use your Apple Watch, KardiaMobile 6L, EMAY device, or Pixel Watch to take an ECG when something feels off—or as part of your regular routine.

Step 2

Upload to Sinoa

Import your recording in seconds. Sinoa supports both 1-lead and 6-lead ECG formats from everyday devices.

Step 3

See what stands out

Sinoa analyzes your recording and highlights patterns, showing where they appear and how consistent they are.

Step 4

Understand and track over time

Get clear, structured explanations and build a history of your recordings so patterns don't get lost.

Step 5

Be ready for real conversations

Share Pattern Summaries and bring something clear into your next conversation with a clinician.

If you are experiencing severe symptoms or think you may be having a medical emergency, seek immediate medical care. Sinoa is not designed for emergency use.

What Sinoa Helps You Do

Capture what matters—even when it's hard to catch

Import ECGs from Apple Watch, KardiaMobile 6L, EMAY device, or Pixel Watch and bring everything into one place. No more relying on a single recording at the wrong time.

See where something actually shows up

Sinoa doesn't just flag a pattern—it shows where it appears in your recording and how consistent it is across segments. Because not everything happens all at once.

Not everything shows up in every recording. Sinoa helps you see what actually did.

Understand what your data is telling you

Each pattern comes with clear, plain-language explanations, including what it can mean, common symptoms, and what may affect how it appears.

Get more than a yes or no

Instead of a single label, Sinoa surfaces pattern context—including partial matches, uncertainty, and when something may be limited by the device used.

Track patterns over time, not just one moment

Compare recordings across days, weeks, and months so recurring episodes don't get overlooked.

Walk into appointments prepared

Bring structured, readable Pattern Summaries that combine your history, pattern insights, and supporting detail in one place.

Keep your data private and in your control

Minimal retention and clear control over what you keep or share.

Why Sinoa

Clarity when it matters most

When something feels off, waiting for answers is the hardest part. Sinoa helps you make sense of your heart data so you're not relying on memory, guesswork, or a single snapshot in time.

Pattern-aware, not just label-based

Most tools give a simple result. Sinoa shows how patterns appear across your recording—even when they're partial or inconsistent.

Transparent, not a black box

See what was detected, where it appeared, and when results are uncertain or limited by the device.

Built for real-world ECGs

Built around everyday device recordings such as Apple Watch and 6-lead monitors including KardiaMobile® 6L and EMAY.

Explanation built into every result—not just a label

Each pattern includes context, symptoms, and considerations so you can actually understand what you're seeing.

Designed for real conversations

Sinoa helps you show up informed and prepared. It does not replace medical care.

Segment-aware ECG analysis

Sinoa shows where a pattern appears, not just whether it appeared.

Typical ECG Experience vs Sinoa

Understanding your heart shouldn't feel like guesswork

Typical ECG Experience

A single result like "Normal" or "Possible AFib"

No explanation of why that result appeared

No visibility into where patterns occur in the recording

One snapshot in time, easy to miss intermittent events

Limited context for symptoms, risks, or next steps

Data scattered across apps or devices

Hard to bring something meaningful into a care conversation

"Looks normal"

With Sinoa

Pattern-aware insights, not just a single label

Clear explanations in plain language for every result

See where patterns appear within your recording

Segment-by-segment breakdown for deeper clarity

Track patterns over time—not just one moment

Everything organized in one place

Structured, shareable Pattern Summaries designed for real conversations

"Stronger match in 1 of 3 segments" — worth discussing

The difference between a single reading and a pattern over time can change the conversation.
