SignPrep is the essential companion for sign language interpreters. It supports your workflow before, during, and after every assignment, helping you prepare, coordinate, reflect, and care for your well-being. ASSIGNMENTS Import assignments from work calendars with smart filtering, or add them manually. View countdowns, locations, directions, preparation progress, notes, and AI briefings in one organised workspace. PREPARATION Prepare with editable checklists, research tools, reviewed web searches, key terms, glossary suggestions, notes, resources, and additional context for AI. With your permission, SignPrep can also use Calendar Notes as relevant preparation context. AI BRIEFINGS Generate a concise briefing for any upcoming or ongoing assignment. Briefings highlight useful context, preparation prompts, key considerations, and areas to research. ONGOING ASSIGNMENT A focused Live Session page designed to stay open throughout an assignment. See progress, timing state, the active interpreter, next swap, and time remaining. Ambient Mode provides a calm, full-screen view for coordinating swaps without breaking focus. SWAP TIMER & SWAP CLOCK Use Swap Timer for structured intervals with Running, Swap Soon, and Swap Now phases, or Swap Clock for flexible turn-taking based on the actual time. Both support A/B interpreter roles, clear swap actions, and glanceable Ambient Mode layouts. APPLE WATCH View assignments and timing information on your wrist. Start or control swap timing from either device and keep both in sync. Complications and Smart Stack cards show what is next or ongoing. WIDGETS, LIVE ACTIVITIES & CONTROLS Widgets show upcoming assignments, countdowns, and CPD progress. One-tap widgets support New Sign, Reflect, and Log CPD. Live Activities and Dynamic Island keep timing information visible during assignments. SIRI & SHORTCUTS Ask about your next assignment, your day, or your swap timer. Start, pause, stop, mute, or adjust timing; open Ambient Mode; log CPD; add a sign; or capture a reflection hands-free. ON-DEVICE AI Apple Foundation Models generate briefings, research, vocabulary suggestions, and preparation checklists tailored to each assignment. Processing happens on your device and is not sent to SignPrep servers. AI output supports, rather than replaces, your professional judgement and trusted sources.

Record clips, tag entries by domain and sign language, review in slow motion, share entries, or export and import your glossary as a SignPrep package. Supports SgSL, ASL, BSL, Auslan, NZSL, and more.
