Sporty's Study Buddy prepares you for the FAA Instrument Rating knowledge test (the "written") with three ways to study: Study Questions, Flashcards and Practice Tests. Questions are organized by knowledge area, with explanations of the right and wrong answers developed by Sporty's team of Master CFIs, based on their experience preparing students for the Instrument Rating. • STUDY QUESTIONS BY TOPIC • Choose whole knowledge areas or individual topics to build your own study session. As soon as you answer, you'll see the correct answer, why it's right, and where to read more. Change your answer anytime, bookmark questions as you go, and jump to any question from the question list. Every study session is shuffled. • REVIEW WITH FLASHCARDS • Flashcards show just the question, so you answer from memory before revealing the correct answer and its explanation. Mark each card Know It or Still Learning, then start a new session from the cards you're still learning. On iPhone Duo, study a card with the phone open and close it to check the answer. • TAKE PRACTICE TESTS • Each Practice Test draws 60 questions at random from the full question bank, gives you 2 hours, and is graded at the FAA's 70% passing score. Afterward, see your score by topic, review every question or only the ones you missed, and turn your misses into a new study session. • PICK UP WHERE YOU LEFT OFF • Sessions save as you go. The History tab lets you resume any session in progress and review past results, including your scores by topic. • EVERY FIGURE, OFFLINE • The Figures tab includes the complete FAA Airman Knowledge Testing Supplement for Instrument Rating, with every figure and legend listed by name and page. Swipe through the pages or open any one full screen. Questions show their figures right alongside, and you can study without a connection. Designed for iPhone, iPhone Duo and iPad, with Dark Mode and support for larger text sizes. The FAA does not publish its knowledge test questions, so the questions on your test won't necessarily appear in this app. Study Buddy is meant to complement your training, not to replace flight and ground instruction.

Verdict

The call

The clearest difference is price: Spark Communicator at Free against Instrument Pilot Test Prep's $14.99. Spark Communicator also leads on rating (5.0 vs 3.1) and update cadence (every 5 weeks vs every 5 months). Instrument Pilot Test Prep's advantage is ratings volume (16 vs 2). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
