HotSummer — turn heat into action

 Heat warnings already exist — bulletins, municipal

ordinances, red alerts. The problem isn't the information, it's that it

stays too generic to act on. HotSummer takes the same data (perceived

temperature, humidity) and turns it into next-hour guidance, tuned to you:

a personal risk index (4 levels, adjustable with an optional health

profile), a recommended time window to stay outside, adaptive hydration

reminders, a three-step alert when risk worsens (notification, short sound

+ vibration, actionable pop-up), the nearest park/green area with

directions, three ways to pick a location (GPS, search, or a point on the

map), and a quick-reference heatstroke first-aid card. No account, no ads,

no data leaving your phone beyond the weather/map requests needed to work

(Open-Meteo and OpenStreetMap, both keyless and trackerless). Not a

substitute for medical advice or official heat bulletins — it complements

them.
