ATC One helps you practice your ATC communication skills by conversing with an AI controller that listens, understands, responds, and evaluates your transmissions like a real air traffic controller.
The AI follows official aviation standards, including ICAO-standard ATC phraseology, proper pronunciation, NATO phonetic alphabet, and real-world communication procedures used in both VFR and IFR operations.
Practice with multiple training modes:
Live AI radio practice
• Flight scenarios (AI) - Realistic, structured scenarios covering multiple phases of flight and standard ATC procedures.
• Readback practice (AI)- Repeat ATC clearances and instructions to improve accuracy, retention, and note-taking skills.
Additional training exercises:
• Phrase Builder - Practice correct call structure and ATC phrase construction through interactive exercises.
• Written exams - Test your readiness for PPL (Private Pilot), IFR (Instrument Rating), and CPL (Commercial Pilot) knowledge exams, with a focus on ATC communications.
Key features:
• Practice real ATC conversations powered by advanced AI
• Customize controller volume, radio static, and cabin noise
• Receive instant feedback after every session, highlighting strengths and areas to improve
• Experience authentic ATC phraseology for both VFR and IFR scenarios
• Train anywhere, anytime — no setup, no instructor required
Played around on the free version and its solid has some issues with voice recognition but not bad training aid if you want to spend some money
Good idea, system needs work
NimbusFlyer27
To start I believe the subscription model is too intrusive to start, I would suggest making a couple exercises free demos to try. The button does not work correctly in both of my devices (iPhone 17 and s26 ultra), when it worked it kept saying “incorrect call sign” the AI needs some refinement on accents and voice recognition for numbers. Overall good idea but greedy-ish and product not finished.
Developer Response
Hi NimbusFlyer27,Thank you for your honest feedback! Fortunately, you can try the full app and all its features for free with our 3-day free trial, so there’s no obligation to subscribe just to test it. Additionally, the app includes hundreds of exercises and features that are completely free.You’re also absolutely right—there were some temporary issues with voice recognition on certain devices a few months ago. The good news is that several versions ago we introduced a completely new, much more advanced proprietary speech recognition system powered by AI.We hope you’ll give it another try and enjoy the improvements!— ATC One Support
Recọmmended.

100% recọmmended. It's a really, really good app. When it cọmes to flight training, there are many apps that—although they work—I've always felt are very poor quality. This app, on the other hand, shows great quality in every aspect: the exercises, design, layout, etc. I really liked it. I recọmmend it.
Nice design

I have used it daily for two months and still have not run out of drills. The variety keeps my learning moving.
• New interactive exercise systems to support a wider range of aviation skills.
• User interface improvements across the app.
• Performance enhancements and general refinements.
