R:B Applicatione

A tactical decision trainer for Ultimate Frisbee players who want to read defenders faster, time their cuts smarter, and never get stalled out again.

Most frisbee drills train your legs. This one trains your brain - the split-second decision of when and where to cut based on the defender's shade, the stall count, and the open lane.

How it works:
You see a top-down tactical field with three players: Handler (H), Cutter (C), and Defender (D). The defender moves based on a behavior script. A live stall metronome counts 1 through 10 with audio cues and haptic ticks. Your job: tap the field at the exact moment and direction you would commit your cut. You are scored on three dimensions:
* Spatial - Did you pick the right lane?
* Timing - Did you read the defender shift and commit at the right moment?
* Stall - Did you commit early enough to avoid the turnover?

What's inside:
* 6 preset drills: In-Cut, Out-Cut, Deep, Under, Swing, and Dump Cut, each with its own defender behavior and optimal cut vector
* Custom drill builder: Design your own scenarios: pick the defender's behavior, set the stall threshold, place handler and cutter starting positions on the field
* Drill setup with custom placement: Tap to position handler and cutter exactly where you want before every run
* Live stall metronome: Three speeds (Slow / Match / Fast), tonal audio per stall band, optional haptic feedback
* Detailed scorecard: Component breakdown for every drill, coaching notes, and replay-ready geometry
* History and stats: Track every run, see your score-over-time chart, hit streaks, and identify your weak spots
* Learn section: Frisbee fundamentals (game rules, roles, stall count, all four cut types, strategy) plus a randomized quiz to test your knowledge
* Daily highlight: A featured drill chosen for you each day to keep training consistent
* Streaks: Build a habit. Train every day, watch the streak climb

This is not a video game - it's a sports-science-backed training tool. Metronome jitter is sub-16ms. Defender paths are scripted on a fixed timeline so your reaction time is comparable run-over-run. Scoring is transparent: every drill record stores the raw geometry, so you can see exactly why a cut earned the score it did.
