Cardiologs

iRhythm Zio Service

Best overall

For everyday users, neither Cardiologs nor iRhythm Zio Service is a direct consumer tool — they are both clinical-grade cardiac solutions. iRhythm Zio Service wins for patients who need a simple, doctor-prescribed wearable monitor with clear instructions, while Cardiologs is built for hospitals and clinics that process large volumes of ECGs. The single biggest difference: iRhythm is a full-service monitoring patch you wear and return; Cardiologs is an AI analysis platform for existing ECG devices.

High diagnostic yield — catches arrhythmias other monitors miss
Patients can log symptoms easily with the MyZio app

Common questions

Can I use Cardiologs on my phone?

No. Cardiologs is a cloud-based web platform for hospitals and clinics. There is no mobile app for patients.

Is iRhythm Zio Service covered by insurance?

Often yes, but it depends on your plan and medical necessity. You'll need a doctor's prescription, and the cost can vary from a copay to several hundred dollars if not covered.

Which tool is better for a small clinic?

Neither is ideal for a small clinic. iRhythm is a patient service you refer out, not a clinic tool. Cardiologs is too expensive and complex for small practices. A simpler, cheaper ECG analysis tool would be a better fit.

Can I get my ECG data out of iRhythm Zio Service?

Not easily. You receive a diagnostic report, but raw waveform data is not typically provided to patients. It's designed for clinical reporting, not personal data access.

iRhythm Zio Service is the practical choice for patients needing a simple heart monitor; Cardiologs is a powerful but expensive AI tool for hospitals — they serve completely different people.

If you're a patient with a suspected heart rhythm issue, talk to your doctor about iRhythm Zio Service — it's a straightforward, wearable patch that does the job without any tech hassle. If you run a hospital or large cardiology practice, Cardiologs can save your team hours of manual review, but be ready for a significant investment and setup time. For everyone else, these tools aren't designed for you — look for a consumer-friendly ECG app or device instead.
