**No subscription required to find out what ARSim can do for you.** Practice aviation radio communication with interactive ATC scenarios, AI-powered controllers, voice recognition, and instant feedback. Build confidence, improve phraseology, and prepare for real-world communication before stepping into the cockpit.....and earn FAA WINGS Credits along the way. The PlaneEnglish Aviation Radio Simulator, or ARSim, helps pilots learn, practice, and improve aviation radio communication through realistic, interactive ATC scenarios. Whether you are a student pilot learning to talk on the radio for the first time, an instrument student preparing for IFR communications, or an experienced pilot refreshing your skills, ARSim gives you a practical way to build confidence outside the cockpit. With AI-powered air traffic controllers, voice recognition, speech analysis, and immediate feedback, ARSim helps you practice aviation phraseology, radio procedures, and real-world communication flows across VFR and IFR flight operations. ARSim includes structured training units designed to build your skills step by step: TRAINER helps you practice full ATC communication scenarios with guided lessons, randomized situations, and feedback on your radio calls. AIRPORT helps you learn airport signs, markings, lighting, and surface operations. PATTERN helps you understand and practice communications in the traffic pattern or circuit. HOLD helps you learn and practice instrument holding procedures. BASICS, GLOSSARY, and RESOURCES provide foundational knowledge, references, and supporting material to help you understand the language and structure of aviation communication. Across the app, you can access hundreds of airports, work through more than 200 lessons, and practice thousands of randomized ATC interactions covering many phases of VFR and IFR flight. Selected training units also allow eligible users to earn FAA WINGS credits...you won't find another communication tool that will do this for you! ARSim training content is guided by FAA and ICAO phraseology, standards, and radiotelephony procedures, helping pilots become more familiar with the communication practices used throughout aviation. For student pilots, ARSim provides an accessible way to build radio confidence before and between lessons. For experienced or non-current pilots, it offers a convenient way to refresh communication skills before returning to training, preparing for a flight review, or getting ready for a checkride. For flight schools and training organizations, ARSim can support more consistent communications practice across students and instructors. Download ARSim to explore the free content available in BASICS, AIRPORT, PATTERN, GLOSSARY, and RESOURCES, and use the free trial period to experience the full functionality of the app. You can also customize your experience in Settings, including phraseology standards, display options, and primary flight display preferences.

CheckPrep is a checkride oral prep app for the Private, Instrument, Commercial and Commercial Multi Add-On practical tests, built around the FAA Airman Certification Standards (ACS), the exact framework your DPE uses to evaluate you. This is not written test prep. This is oral prep. STUDY THE WAY YOUR DPE TESTS YOU Every question, answer and reference is organized by ACS Area of Operation and Task, the same structure your examiner follows. Every card maps to an ACS task, so every minute of study maps to your oral exam.

Tap a citation on a study card to open the exact paragraph, page or ACS element. Bookmark passages, search by keyword, read offline after download. AIM paragraphs also open on the FAA website, so you never have to wonder whether it is current. KNOW WHEN YOU'RE READY Mastery is tracked from 0 to 100% for every ACS task. Flash cards and multiple-choice quizzes are built from the same cards. Switch on the Needs Review filter to limit a session to the cards you still miss and leave the mastered ones out. When every task reads 100%, you know where you stand before the examiner does. DECODE REAL-WORLD WEATHER METAR, TAF and PIREP decoding practice with live data from aviationweather.gov. Included free. TRAIN YOUR EAR Departure (CRAFT) and approach (P-TAC) clearance trainers read the clearance aloud. You give the readback by voice. Beta, included with the Instrument guide.

Verdict

The call

The clearest difference is rating: CheckPrep at 5.0 against PlaneEnglish's 4.1. CheckPrep also leads on update cadence (every 4 days vs every 5 weeks). PlaneEnglish's advantage is ratings volume (326 vs 4) and iOS requirement (18.6 vs 26.2). On price, ads, in-app purchases and monetization model there is nothing between them.
