◆ BACKSTOP
the book, kept from the stands
Below Triple-A, nobody is tracking pitches. Except you.
Backstop is a free pitch-charting app for minor league games. Chart every pitch from your seat in two taps, ride along with the live Gameday feed, and walk out with heatmaps, count tendencies, an ump scorecard, and a shareable scouting card.

Chart in two taps

Tap where the pitch crossed, tag the result. Press-drag to fine-tune, or flip on coarse mode for honest nine-cell charting from an angled seat. Velo, pitch type, and contact quality when you want them.

The feed rides along

Live scores, count, baserunners, and due-up batters for every affiliated club. Triple-A games stream real pitch tracking next to your chart. Below AA — your chart is the only book in the building.

Study, then share

Heatmaps, velocity fatigue, sequences, count tendencies, spray charts, and an umpire scorecard with the night's biggest miss in inches. Export scouting cards as images, and your whole season as CSV.

Yours, on-device

No account. No tracking. Everything saves to your phone, with one-tap JSON backups.
