Your watch said "irregular rhythm."
Before you spiral — let a cardiologist look.

Smartwatch alerts save lives. They also produce an enormous number of false alarms — and every one of them costs someone a sleepless night, a panicked search spiral, or a four-figure ER visit for what turns out to be a shaky sensor reading. Alarm Check is the missing middle step: send the actual strips, and a board-certified cardiologist tells you what they show — within hours, for $39.

Hours

not weeks — an answer the same day, with the reasoning

When NOT to use this: chest pain, fainting, severe shortness of breath, or an alert accompanied by feeling truly unwell — that's a 911 call or emergency department visit, now. Alarm Check is for the alert that arrived while you feel fine.

How it works

Export your recordings — Apple Watch ECG PDFs, Kardia recordings, or screenshots of the alert history. We show you exactly how (it takes about two minutes).

A cardiologist reads the actual tracings — not the watch's algorithm, the raw strips. Any device, any brand.

You get a signed answer: what the rhythm is, why the watch flagged it, whether it needs follow-up — and if it does, precisely what kind and how soon. If it doesn't, you get the reason in plain English, plus the specific things that would make it worth re-checking.

Why this exists

Device makers legally can't tell you "you're fine" — their alert has to end with "consult your doctor." A licensed physician reviewing your tracings can actually answer the question.
We explain the mechanism — why a skipped-beat run at 2am is usually benign ectopy, what adrenaline does to your rhythm — because understanding is what actually lets people stop checking their pulse 40 times a day.
