BeatTheHeat

A consumer heat-safety app that gives fair-goers, construction workers, and outdoor exercisers hyperlocal WBGT readings, hydration reminders, and a 'find shade' map for nearby parks and businesses.

Target user

Outdoor workers and consumers spending long hours in summer heat (construction, fair-goers, runners)

Features
  • Hyperlocal WBGT reading using your phone's sensors plus nearby weather stations
  • Personal heat-burn tracker that estimates how long until you need shade based on activity intensity
  • Map of nearby cooling centers, public pools, and AC-equipped cafes
  • Push alerts when the heat index crosses your personal risk threshold
Why now

CDC-reported surges in heat-related ER visits and fair closures for heat show consumers need a personal early-warning system, not just generic forecasts.

Demand
4/10

Multiple existing apps already serve this need: Tempest's HeatAlert provides real-time WBGT with NWS suggested actions, and the OSHA-NIOSH Heat Safety Tool is a free government app for outdoor workers, indicating modest but crowded consumer demand.HeatAlert: An Weather App to Beat the HeatHeat Safety Tool App (OSHA-NIOSH) | CDC

Whitespace
3/10

Core WBGT + heat-index niche is already occupied by HeatAlert (WBGT-focused) and the free OSHA-NIOSH app; only a shade-finding map and fair-goer framing would differentiate, leaving narrow whitespace.HeatAlert: Heat Stress Index - App StoreOSHA-NIOSH Heat Safety Tool - heat.gov

Monetization
3/10

The dominant competitor (OSHA-NIOSH) is free, and HeatAlert appears free/download-based; willingness-to-pay for hyperlocal WBGT reminders is unproven for consumers versus workers who already get it gratis.OSHA-NIOSH Heat Safety Tool - App StoreHeatAlert: Heat Stress Index - Google Play

Longevity
8/10

Climate change is driving sustained year-over-year increases in heat waves and extreme-heat ER visits, supporting long-term demand for heat-safety tooling.Heat - Overview: Working in Outdoor and Indoor Heat Environments - OSHA

Feasibility
7/10

WBGT relies on sparse station data (often proxied via heat index), and a shade map is buildable via Google Places/Overpass, but combining reliable WBGT feeds with curated shade POIs is non-trivial.Heat Forecast Tools - National Weather Service
