BeatLog
The symptom diary your Holter or patch monitor came with — in the browser
One tap stamps the exact clock time the moment a symptom hits, then you pick the symptom and activity from the AHA picklist. Set your monitor's start time and ID once and hand the clinic a clean timestamped report instead of the paper sheet. Free, no account.
Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.

What you can do in BeatLog on the web
One tap, exact time
The big LOG NOW button stamps the clock to the second the instant a symptom starts — no typing, no recall, no reconstruction hours later.
The AHA picklist, built in
Palpitations, dizziness, chest pain, shortness of breath, near-fainting, unusual fatigue or other — and sitting, walking, exercising, eating, taking medication, sleeping or stressed.
Set the monitor once
Holter, patch or event recorder, its label, device ID, exact start time and planned wear days — every entry is measured from that moment.
Diary timeline against the wear
Every event grouped by day with its seconds tick and how far into the wear it fell, e.g. 1d 03h 12m in.
A clinic report you can hand back
Session details, symptom breakdown and the full chronological list — download it as a printable text report or a CSV, or copy it.
Severity, notes and corrections
Rate 1–5, add a line like “fluttering, about 20 seconds”, and nudge the time if you tapped a moment late.

The empty-day nudge, your local data counts, backup, sample data and erase.
Try it with sample data: Adds a 7-day Zio XT patch wear started 52 hours ago and eleven timestamped events across it — palpitations while stressed, near-fainting on a walk, shortness of breath on the treadmill and more, each with an activity, severity and note. You can start fresh at any time.

Questions
Is the web version of BeatLog free?+
Yes. Sign in with a free All Things AI account and use every screen — no subscription, no in-app purchases.
Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Do I need an account?+
You can read about the app without one, but you must sign in to open it. Sign-in is free and takes a few seconds with Google.
How is the web version different from the BeatLog iPhone app?+
A browser tab cannot post a local notification through a 7–14 day wear, so the logging reminder appears as a nudge on the Log screen when you open it rather than as a push. The clinic report downloads as a printable plain-text file or a CSV rather than the formatted multi-page PDF the iPhone app renders. Your monitor session and every timestamp live in this browser's storage — a different browser or device starts empty, so export a backup before the clinic visit.
