 HOTSUMMER by Survival-apps

Heat warnings already exist — bulletins, 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.

## What it does

Personal risk index

Not just air temperature — perceived temperature in 4 levels. An optional profile (age, weight/height, outdoor activity, health conditions) lowers the alert thresholds if you're more vulnerable to heat.

UV index & air quality

Alongside temperature and humidity: UV index (WHO scale) for sun protection, and air quality (European AQI) to know if today is fine for your lungs too, not just the heat.

Safe-window estimate

"You can stay out until HH:MM" instead of a generic bulletin to interpret yourself.

Adaptive hydration reminders

The interval tightens as risk rises — not a fixed timer for everyone.

Escalation alert

Notification, a three-tone chirp, and an amber Pip-Boy-style pop-up with hour-by-hour advice — only when risk actually worsens, never on first launch.

Nearest green space

The closest park, forest or reserve (name, distance, compass-driven arrow), one tap to get walking directions via Google Maps.

Three ways to pick a location

Current GPS position, search by name, or a point chosen by hand on an embedded map — useful for where you'll be working tomorrow, or where a relative lives.

Heatstroke first aid

One tap away: warning signs, what to do immediately, cooling measures, when to call emergency services.

No account

No ads, no data leaving the phone beyond the weather/map requests needed to work (Open-Meteo and OpenStreetMap — both keyless, no tracking).

## Privacy & verification

Not a substitute for medical advice or official heat bulletins — it complements them. Risk recalculates when you open the app or pull to refresh, not continuously in the background.
