Zeus Call

Zeus Call is an offline-first sports-officiating studio for rec-league volunteers, intramural referees, PE teachers, and new umpires. It is not a scorekeeper, not a game diary, and not a static rule PDF. The core loop is timed signal-recognition drills and branching what's-the-call scenarios, with seed basketball, volleyball, and soccer packs so day one already feels like a full classroom.

Build real rec-league call confidence instead of rereading a rulebook.

TIMED SIGNAL DRILLS
Work basketball, volleyball, and soccer chips against the clock. Pick a speed level, read the pose, and get an instant ruling explainer after every rep so the mechanic sticks.

WHAT'S-THE-CALL SCENARIOS
Step into branching situations at the table, net, box, and midfield. Each path ends with the official restart and a live-ball or dead-ball outcome, so you practice the full call—not a trivia answer.

SIGNAL LIBRARY
Search 40+ seed poses on oversized 3D-style cards with mechanic notes. Turn on left-handed mirror mode when you work the opposite side of the floor.

MOCK EXAMS AND MINI-LESSONS
Run scored rec-league practice exams with a weak-signal spotlight that sends you back to the drills you missed. Exams are educational only and do not confer federation certification. Short mechanic lessons cover travel, double dribble, lift, net touch, offside basics, and advantage/play-on.

CREW TOOLS
Study two-person positioning boards, who-mirrors-whom checklists, and pre-game conference prompts. Keep timeout, substitution, and injury-stop protocols in a structured crew phrasebook.

PRACTICE THAT FITS THE WEEK
A daily five-signal widget and practice reminders keep reps going without any game logging. Favorite sport, timer cadence, and bookmarked signals stay on device. Color-blind-safe foul and whistle palettes, large-type drill mode, and haptic tempo cues stay readable in loud gyms and outdoor courts.
