Ongoing Assignment
A dedicated full-screen page designed to stay useful throughout an assignment. See what is happening now, how much time is left, and which timing tool is active.
Prepare, interpret,
reflect, and recover.
SignPrep helps sign language interpreters manage assignments, prepare with on-device AI, coordinate interpreter swaps, track CPD, build a sign glossary, and care for their well-being — before, during, and after every job. All on-device.

New in v1.5
Built for the live assignment
SignPrep v1.5 brings the app closer to the way interpreters actually work during an assignment. Open the Ongoing Assignment page, choose the timing style that fits the session, and set the phone down in Ambient Mode so the swap timer stays readable at a glance.
Ambient Mode
A set-it-down view for live sessions. Rest the phone nearby and read the swap timer at a glance — large text stays legible from a distance, and the colours pulse when it is time to swap, so you never reach for the screen mid-assignment.
Swap Timer & Swap Clock
Use Swap Timer for structured intervals, or Swap Clock when turn-taking needs to follow the real clock. Both support A/B interpreter roles and a consistent live-session experience.
Built by an interpreter who lives the work — every feature comes from real assignments, real prep, and real reflection.
Designed by a practising sign language interpreter based in Singapore
- 100% on-device & private
- Powered by Apple Intelligence
- Free on iPhone, iPad & Apple Watch
Before, during & after every assignment
One app for your entire interpreting workflow
Built as the all-in-one interpreter app, SignPrep gives sign language interpreters the tools to prepare for every assignment, reflect on their practice, and take care of their well-being — end to end. See the full list of features for sign language interpreters.
Assignments
Every job, ready before you walk in
Import from your work calendars with smart filtering, or add your own jobs with a Calendar-style editor. Each assignment shows a live countdown, one-tap directions, and a preparation checklist generated by on-device AI based on the domain, title, and location.
- Live countdown to every assignment
- One-tap Apple Maps & Google Maps directions
- AI pre-briefing when a job is within two hours or ongoing
AI Preparation
Briefings and vocab, generated on your device
On-device Apple Foundation Models generate topic research, vocabulary suggestions, briefings, and prep checklists tailored to each assignment — no data leaves your phone. Open a job and get a clear briefing on what to expect, plus a checklist you can tick off.
- Context-aware briefings per domain & location
- Auto-suggested preparation checklists
- Runs locally — private by design
Swap Timer & Swap Clock
Coordinate every interpreter swap
Use Swap Timer for structured intervals — a 3-phase countdown (Running, Swap Soon, Swap Now) with haptic cues. Or switch to Swap Clock when turn-taking needs to follow the real clock. Both support A/B interpreter roles and an Ambient Mode you can set down and read at a glance during live sessions.
- Control from the Lock Screen, Dynamic Island & Control Centre
- Interactive Live Activity: Swap, Restart, Pause, Stop
- Start or control it from Apple Watch & Siri
Sign Glossary
Your own searchable sign library
Build a searchable video library of signs. Record clips, tag by domain and sign language, review in slow motion, share as visual cards, or export your collection. AI suggests related words you may not have thought to record.
- Works for interpreters of any sign language
- Slow-motion review and shareable visual cards
- AI vocabulary and related-word suggestions
DC-S Reflections
Reflect with the Demand-Control Schema
Structured DC-S prompts for environmental, interpersonal, paralinguistic, and intrapersonal demands. An interactive DC-S quiz helps you identify categories in real scenarios, and you can flag entries for mentor discussion.
- Track your weekly reflection streak
- AI-suggested demands based on assignment context
- Export all reflections as PDF or CSV with date filtering
And more
Everything else that runs your practice
CPD Tracking
Log continuing professional development by activity type with country-specific defaults for RID, NRCPD, and NAATI. Set your target and renewal period; SignPrep tracks your pace and alerts you within 30 days of renewal. Export as PDF or CSV.
Self-Care
Log mood daily and visualise trends. Track fatigue and cognitive load with colour-coded check-ins, follow guided breathing and interpreter-specific stretches, with AI suggestions drawn from your reflection history.
Apple Watch
View assignments and the swap timer on your wrist, with four complication families and Smart Stack cards that surface what's next. Start or control the timer from either device — they stay in sync.
Widgets & Live Activities
Home and Lock Screen widgets show greetings, upcoming assignments, CPD progress, and countdown gauges. One-tap New Sign, Reflect, and Log CPD shortcuts, plus Control Centre controls.
Siri & Shortcuts
Ask "What's my next assignment?", "What's my day like?", or "What's my swap timer status?". Start, pause, and stop the timer by voice. Log CPD, add a sign, or capture a reflection hands-free.
Resources
An interactive Code of Professional Conduct with seven tenets and real-world examples, customisable role cards for hearing clients, and region-specific links to your national association and Deaf community organisations.
Private & accessible, by design
SignPrep is built to honour the Code of Professional Conduct and its tenet of confidentiality. Your assignment data is read only from your own calendar, never leaves your device, and is never sent to a server. Every briefing, topic research, and glossary suggestion is generated entirely on your device using Apple's on-device Foundation Models — so the people you interpret for stay private to you alone.
- Confidentiality first. Designed around the Code of Professional Conduct so consumer and assignment details never leave your control.
- From your calendar only. Assignments are retrieved from your own device calendars — nothing is uploaded or shared.
- Never leaves your device. All assignment data stays on your iPhone, iPad, and Apple Watch — no servers, no cloud, no tracking.
- On-device AI. Briefings, topic research, prep checklists, and glossary suggestions are generated locally with Apple's on-device Foundation Models.
VoiceOver works on every screen, widget, Live Activity, and Watch complication, with Dynamic Type, high-contrast colours, and haptic feedback throughout. Spotlight indexes your glossary and assignments — all without your data ever leaving your device. Read the full privacy commitment.
Be ready for every assignment.

Built with interpreters, for interpreters
Thank you to every sign language interpreter who uses SignPrep — your work inspires this app, and your practice shapes it. SignPrep gets better because of the interpreters who share what they need. If you have feedback, a feature idea, or something that would make your assignments easier, I'd genuinely love to hear it.
