I need an android and iOS- GPS application that speaks my users’ language—literally. Every map label, menu item, and spoken direction must appear in clear Persian, produced on-device with AI translation so the experience feels native rather than a simple overlay. Core functions • Turn-by-turn navigation that switches smoothly between English map data and Persian voice/text guidance. • Real-time traffic updates pulled from a reliable feed and translated instantly so delays, incidents, and ETA changes are easy to understand. • Location search supporting both Persian and Latin input, returning ranked results in Persian. Technical notes Native Swift or Objective-C is fine, but the finished build must sit comfortably in Apple’s review guidelines. Feel free to use MapKit, Google Maps SDK, CoreLocation, CoreML, or a third-party NLP engine—whichever combination keeps latency low and translations accurate. Offline caching for routes and language models is a plus. What I’d like to see from you Show me your relevant experience shipping location-based or multilingual apps. A concise note on how you would handle on-device translation, map data licensing, and performance optimisation will help me decide quickly. Deliverables (acceptance criteria) 1. TestFlight build demonstrating the three GPS features above, fully localised in Persian. 2. Xcode project with clean, documented code. 3. Brief hand-off guide covering translation pipeline, map data source, and how to add more languages later. Once the build meets these points and passes a short live test in Tehran’s streets, I will sign off and release final payment.
