How it works
First Base pulls live standings from Hot Stove and 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.
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. Your older kid's 9u tournament and your younger kid's 10u tournament, 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. GameChanger games and practices flow in automatically when connected.
Hot Stove is the foundation — reliable, public, always there. Connect your GameChanger account for live-ish in-progress scores that fuel provisional odds. If GameChanger goes dark, the app stays fully usable. GC never degrades the Hot Stove experience.
Everything included
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.
Optional: connect your GC account for in-progress score freshness and provisional live odds. GC failure never breaks the app.
Your team's odds and next game on your lock screen while the tournament runs. Updates automatically with First Base Plus.
Completed tournaments are saved to disk forever. Old events load instantly, work offline, and are durable even if the site drops old data.
Everything lives on your device. Zero sign-up, zero data collected, zero servers to go down. Your data is yours.
Free to download — no account, no setup, no surprises.
