About this app

Where is everyone playing right now?

HeatZone shows which courts and fields near you are busy this hour. Players drop an anonymous pin where they're playing, and HeatZone turns those pins into a live heatmap. No feed, no followers, no profiles: just a quick answer before you head out.

How it works
• Open the map and see the heat around you. The hotter the zone, the more people are playing there right now.
• Tap a zone to see which sports are being played, how many pins are active and how long it's expected to stay busy.
• Playing somewhere? Drop a pin in two taps: choose your sport and how long you'll stay (30 minutes, 1 hour or 2 hours).
• The zone lights up for everyone nearby. When your time is up, your pin disappears on its own.
• Nobody there yet? Drop the first pin and the zone goes live for everyone.

Sports
Pickleball, basketball, soccer, tennis, volleyball, football and baseball, plus "Other". Pick the ones you play and the heatmap shows them by default, or filter it by sport.

Live, not historical
Heat only reflects pins that are active right now. Every pin expires on a timer, after three hours at most.

Anonymous by design
• No sign-up, no name, no profile.
• Pins are placed on a 25-meter grid, not at your exact position.
• Your location is only used to center the map and place your pin. You can browse the heatmap without it.
• "Delete my data" in Settings removes your live pins and your anonymous account at any time.

Also in HeatZone
• A reminder five minutes before your pin expires, with a button to add 30 minutes. It's the only notification HeatZone sends, and you can turn it off.
• The Live tab lists the active zones near you.
• Directions to any zone.
• Report a zone that doesn't look right.
• Light and dark appearance, and a language setting inside the app.

Free, with one optional purchase
Every feature in HeatZone is free. The app shows an ad banner; if you'd rather not see it, a one-time purchase removes it for good on every device with your Google account. No subscription.
