The UK is in a record-breaking heatwave with 35C highs, hosepipe bans affecting 5 million people, and amber UKHSA health alerts; weather apps don't translate this into the practical, UK-specific guidance people actually need.

A dedicated search for a UK 'heatwave app' on iOS/Android returned zero hits; existing alternatives are static gov.uk checklists, a Red Cross PDF, and a basic heatwavetoolkit.com website — no personalized UK-specific app combining Met Office + hosepipe + NHS alerts exists.Beat the heat: keep cool at home checklist - GOV.UK ↗Heatwave Toolkit - Solutions for a UK Heat Emergency ↗
Hyper-seasonal use window (a few hot weeks/year) limits subscription viability; UK weather apps are predominantly free/ad-supported and the main UK cool-home guidance (gov.uk, Red Cross, Heatwave Toolkit) is free, suggesting weak willingness to pay for a niche utility.2025 Mobile App Report: LTV, Paywalls & Pricing Benchmarks ↗Heatwave Toolkit - Solutions for a UK Heat Emergency ↗

Buildable but non-trivial: Met Office DataPoint API, UKHSA alerts, and water-company APIs are accessible, but aggregating them with UK-housing-stock logic (terrace, flat, loft type, ventilation patterns) into a personalised checklist requires real product work.Heat-Health Alerts issued by UKHSA and the Met Office - GOV.UK ↗
