ATC Copilot

ATC Copilot transcribes air traffic control radio in real time, entirely on your device. No internet, no servers, no account — your audio never leaves your iPhone.
Built on a speech model fine-tuned specifically for the clipped, noisy, fast-paced language of ATC communications, it turns live radio into readable text and highlights the items a pilot must not miss.
KEY FEATURES
• Fully offline — all processing runs on-device with Apple Neural Engine acceleration
• Real-time live transcription that streams word by word as you listen
• Safety-critical highlighting — runways, altitudes/flight levels, headings, speeds, frequencies, squawk codes and QNH stand out automatically
• Current-instruction strip — the latest assigned runway, altitude, frequency and more, at a glance
• ATC-aware formatting — phonetic letters and spoken numbers are rendered the way pilots read them ("two seven left" → "27L", "alpha charlie" → "AC")
• Private by design — nothing is uploaded, cached, or shared
WHO IT'S FOR
Student and rated pilots building radio comprehension, aviation enthusiasts following live ATC, and anyone who wants a private, offline record of what was said on frequency.
IMPORTANT
ATC Copilot is a transcription and study aid only. It is not certified for, and must not be used for, real-time flight operations, navigation, separation, or any safety-of-flight decision. Always rely on official communications and approved equipment. Transcription accuracy is not guaranteed.
