Heat Check: Live Stats Tracker

Heat Check - know who's hot, while it's still happening.

Every other sports app is built around the final score. Heat Check is built around the run.

THE HEATER BOARD
A live, ranked list of the hottest players on right now - NBA, MLB and NFL - reordering itself as the night moves. Someone catches fire in the third and climbs. Someone sits and slides. There's a board per league and an All board that merges them, which answers the question nothing else does: out of everything on television right now, where should I be looking?

THE HEAT INDEX
One live number per player, weighted hard toward the last few minutes. It reads volume against efficiency, rewards streaks as they extend, counts all-around production, and factors in whether the game is actually close. And it cools - a player who sits or goes quiet drops, on a schedule. Heat that can't fade isn't heat.

ALERTS WITH A VOLUME KNOB, NOT A SETTINGS MAZE
One control, three settings:
- Just the big ones: only the rare, nuclear nights
- Keep me warm: players heating up, up to 8 an hour
- Blow up my phone: every heater, no mercy

The cap is enforced when alerts are sent, not estimated. When more happens than your setting allows, you get the best moments of the night, not the first ones to clear a threshold before your budget ran out. Pick your sports, set quiet hours, done.

NEW: ALERTS WORK WITHOUT AN ACCOUNT
Your phone registers itself on first launch. Choose your intensity and alerts start arriving: no email, no sign-up, nothing to fill in. Sign in later and everything you set up comes with you, merged rather than replaced. Signing in is now about having your list on every device, not about whether the app works.

NEW: SEE WHAT YOUR ALERTS ARE DOING
Your profile now shows the night: how many you've been sent, this hour against your budget as a slot meter, a by-hour breakdown, and the last alert you got. When we don't have the figures, it says so rather than showing you a zero.

MARKET DATA FROM KALSHI RESEARCH - DISPLAY ONLY
See what the market thinks next to what the players are doing. Live win probability on game cards with the margin stripped out and movement since the current half-inning or quarter. Player prop markets in Insights: the current number, the best available on each side with the book named, where it sat at kickoff, and how often recent games cleared it. Kalshi price ladders where they exist, each with its own freshness stamp.

Every figure names its source - published consensus, an average across the books quoting it, or Kalshi - so you always know what you're reading. Nothing is tappable, there's no handoff and no account to fund: it's context, not a wager. One switch in your profile turns all of it off.

LIVE ACTIVITIES AND DYNAMIC ISLAND
Put a player's heat on your Lock Screen and leave your phone face-up. Photo, club colours, live line, and a heat bar that moves as the game does. You pick the phone up because something is happening, not to find out whether it is.
