How it works
First Base pulls live standings from Hot Stove, East Coast and Tourney Machine, then runs 10,000 Monte Carlo simulations every refresh. You see the full picture — where every team stands and what percent chance each one has of making the bracket.
Every kid’s games across every event you follow, in one agenda. Rain risk comes from the forecast at the field, not at your house. Departure times account for the traffic expected around the time you want to arrive — and a slider on each game sets how early that is, whether you roll in at first pitch or ninety minutes ahead for warmups.
Rain risk is a forecast, never a cancellation. No league publishes those anywhere a phone can read, so when it looks bad First Base tells you to watch for the call rather than pretending to know.
Pin as many teams and events as you follow. The Today view shows your focused event; a single tap shifts focus to the next one. Seasons, tournaments, multiple kids — First Base Plus keeps them all, side by side.
Tap your team and see the full picture: record, playoff odds, and a chronological timeline of every completed and upcoming game — including results.
Hot Stove and East Coast are the foundation — reliable, public, always there. When a game's in progress, live scores flow in to fuel provisional odds — clearly labeled. If live data goes dark, the app stays fully usable; it never degrades the standings you count on.
What's inside
10,000 simulations every refresh. Not a simple win-percentage — a full bracket projection that accounts for the actual remaining schedule.
Runs allowed, head-to-head, coin toss — the real Hot Stove tiebreaker rules, implemented exactly. No approximations, no wrong rankings.
When a game's on, live scores flow in and your odds update — clearly labeled provisional. If live data goes dark, the app stays fully usable.
