Aerivity: The All-in-One VO₂ Max & Metabolic Intelligence Platform Transforming UK Longevity Clinics
Discover how Aerivity — built by Xharvoc — is revolutionising VO₂ max testing, metabolic analysis, and longevity clinic operations with AI-powered reports, white-label branding, full accounting, and 11 integrated platform modules.
The longevity and metabolic testing industry is booming across the UK, yet most clinics still rely on a patchwork of spreadsheets, manual PDF reports, separate booking tools, and disconnected accounting software. Aerivity, developed by Xharvoc, is changing that — delivering a single, intelligent SaaS platform purpose-built for VO₂ max, lactate, and metabolic testing clinics.
In this comprehensive deep-dive, we explore every module, the clinical science behind it, and why Aerivity is the operating system longevity clinics have been waiting for.
Clinics Deserve Better Than Spreadsheets
Modern performance and longevity clinics run advanced VO₂ max, lactate threshold, and heart-rate recovery tests — but behind the scenes, the workflow is anything but advanced:
- Manual reports: Hours of copy-pasting breath-by-breath data into branded PDFs — prone to errors and delays
- Scattered booking: Separate calendar apps, reminder tools, and intake forms with no integration
- Fragmented billing: Invoicing in one tool, accounting in another, payroll somewhere else entirely
Data gets lost between systems, reports take hours to produce, and billing always falls behind. Aerivity eliminates all of this.
One Platform, Everything Connected
Aerivity connects your test data, client management, branded reports, booking system, and full finance suite into a single, white-label platform designed specifically for performance and longevity clinics.
🔬 Clinical Core
1. VO₂ Max & Metabolic Analysis
From Raw CSV to Clinical Insights in Seconds
Import data directly from any metabolic cart — PNOĒ, COSMED, VO₂ Master, or any device that exports CSV/Excel. Aerivity automatically calculates:
- VO₂ max, anaerobic threshold (AT), RER, and ventilatory thresholds from raw time-series data
- Fat-burn vs carbohydrate oxidation crossover charts with interactive visualisations
- Heart rate zone analysis with ACSM-standard zone boundaries
- Lactate curve plotting with automated threshold detection
- Longevity scoring algorithms with risk flag detection and biological age assessment
No hardware lock-in — Aerivity is completely hardware-agnostic. Clinics keep full data continuity when switching devices.
