BP, ABPM and lifestyle journal — in development
ABPM is gold standard but home logs are a mess. £0 PWA gives GPs structured 24h data without hardware change.
The gap we're addressing.
Around 14 million UK adults are estimated to have high blood pressure, and ambulatory blood-pressure monitoring (ABPM) is the gold-standard diagnostic. NHS ABPM hardware is in short supply, and home BP machines are now under £30 — but the data they produce is usually a scribbled paper log a GP cannot trust. We're wasting clinical time on bad data, not bad patients.

What's actually novel.
HeartLog turns the cheap home BP monitor into a clinic-credible logging device. ABPM Mode runs a structured 24/36/48-hour window with reminders and pattern detection; lifestyle tags capture tinnitus episodes, reflux, hearing changes and sleep; the export is a clinic-ready PDF in standard ABPM format.
- ABPM 24/36/48-hour structured windows with daytime/nighttime aggregation.
- Medication and lifestyle log alongside readings — tinnitus, reflux, hearing, sleep, stress.
- Clinic-ready PDF export aligned with NICE guidance on ABPM reporting.
- £0 to the patient. GDPR-first: data stays local unless the patient opts to share.
- PWA, works offline, no app store, no upsell.
Honest about early-stage.
In development. Early build tested by the founder during a real GP-issued 24h ABPM in May 2026. Not yet released for general use. The product is live and self-funded; the role of grant capital is to add the rigour, cohort study and independent review that a self-funded team cannot deliver alone.
How the system works.
HeartLog is a structured ambulatory journal with a lifestyle correlation engine. Each reading is timestamped, contextualised (sitting/standing/lying, arm, post-rest), and tagged. Aggregations follow NICE-style ABPM reporting conventions so a GP can read it like a hospital print-out.
Schedule
Patient selects 24, 36 or 48-hour window. App schedules reminders for active-day and overnight readings.
Capture
Each reading recorded with systolic/diastolic/HR, position, arm and contextual tags.
Correlate
Lifestyle tags (caffeine, alcohol, salt, stress, tinnitus, reflux) overlaid on the trend graph for visible cause-effect.
Export
Clinic PDF: 24h average, daytime average, nighttime average, dipping pattern, annotated reading log.
Three plausible tiers of funding.
Figures illustrative and indexed to UK grant call sizes we're shortlisted against. Each tier delivers a discrete, publishable milestone.
Independent GP / cardiology review of the PDF export against NICE NG136 / BHS standards, accessibility audit, and a 50-patient self-reported feedback round.
12-week pilot at 2 primary-care sites. Time-to-diagnosis comparison vs. NHS ABPM device pathway. Published methodology and v2 of the export.
Integration with NHS App / GP Connect, formal evidence package to NICE ESF, multi-language reading-age variants, and a consented research cohort.
