# Best EKG Monitor With a Built-In Screen (No Phone Needed)

> Why a personal EKG with its own screen and no phone or subscription is easier to use during a symptom — and how the SonoHealth EKGraph delivers an instant on-device reading.

The best EKG monitor with a built-in screen is one that shows your result on the device itself in about 30 seconds — no phone to unlock, no app to open, and no subscription. The SonoHealth EKGraph does exactly this: an FDA-cleared single-lead ECG with its own LCD that classifies each trace on the spot, for \$79. It screens and tracks your heart rhythm; it does not diagnose.

<Warning>
  A personal EKG cannot rule out a heart attack. If you have chest pain, fainting, or severe shortness of breath, **call 911** — do not stop to record a trace.
</Warning>

## Why does a built-in screen matter?

Palpitations are often brief, so the moment they hit is when you want to record — and fumbling to unlock a phone and open an app can cost you the reading. A monitor with its own screen lets you touch the sensors and see a classification immediately, which many people find simpler, especially [seniors](/ekg/best-personal-ekg-for-seniors) or anyone who isn't phone-first. See [how a home EKG works](/ekg/overview).

## Screen-based vs. app-only EKGs

Many personal EKGs are **app-first**: the device is a sensor and your phone is the screen. That works, but it adds a step and sometimes a paid membership for storage. A **screen-based** device is self-contained — useful when you want to hand it to a spouse or parent, or record without your phone nearby. Compare the two approaches in [EKGraph vs. KardiaMobile](/ekg/ekgraph-vs-kardiamobile) and [personal EKG vs. smartwatch](/ekg/personal-ekg-vs-smartwatch).

## What to look for in a no-phone EKG

| Priority             | Why it matters                                |
| -------------------- | --------------------------------------------- |
| On-device screen     | See the result instantly, no phone needed     |
| Fast reading (\~30s) | Capture a symptom before it passes            |
| No subscription      | Storing your own history shouldn't cost extra |
| Optional app sync    | Export a PDF for your doctor when you want to |
| FDA clearance        | Confirms it's a real, tested single-lead ECG  |

The [EKGraph](https://sonohealth.com/products/ekgraph-portable-ekg-monitor-detect-afib-abnormalities) meets all five: an on-screen reading in \~30 seconds, free unlimited cloud storage with no subscription, optional Bluetooth sync to the free app (iOS & Android) for PDF export, and FDA 510(k) clearance — plus a 2-year warranty, 60-day trial, and FSA/HSA eligibility.

## Does "no phone" mean no records?

No. The EKGraph shows results on-screen *and* can sync over Bluetooth to store an unlimited, dated history you can export as a PDF — so you get standalone convenience without giving up a shareable log for your [doctor](/ekg/when-to-see-a-doctor-heart).

<Note>
  A personal EKG documents and tracks rhythm; it is not a diagnosis. Always review abnormal or worrying readings with a healthcare professional.
