Prepware Remote Pilot UAS

Review by eFreeware

Prepware Remote Pilot UAS is a study and test tool for the FAA Remote Pilot knowledge exam, the written test that stands between a drone operator and a Remote Pilot Certificate for non-hobby work. It comes from Aviation Supplies & Academics, and it carries nearly 300 sample questions with answers and explanations. The app costs $4.99, shows no ads and offers no in-app purchases.

That focus is the most distinctive thing about it. This is not a general drone app or a flight-planning tool. It exists to get you through a specific exam, and everything in it points at that goal. The developer aimed this app at people studying for a small UAS remote pilot rating.

Who ends up using a study app like this

Existing manned-aircraft pilots who want to understand drone operations and how they share the National Airspace System are also named as a fit.

What those groups have in common is a test date and a body of material to absorb. A Part 107 candidate studying after work, an instructor running a ground school, or a licensed pilot adding a rating all need the same thing: questions in the exam's format, with explanations that make the reasoning stick. The app is built around that need rather than around flying itself.

I would not treat it as a substitute for understanding the material. It is a question bank with instructional support, and it assumes you are working toward a certificate. The value shows up when you use it steadily over the weeks before an exam, not when you install it the night before.

Studying by subject, with explanations attached

The core of the app is its question set. Nearly 300 sample questions come with answers and explanations, and the material is organized into chapters by subject rather than presented as one undifferentiated pile. The subjects covered are Regulations, National Airspace System, Weather, Loading and Performance, and Operations. That breakdown matters because the exam draws on several distinct areas, and studying by topic lets you spend time where you are weakest.

Each question comes with an answer stem, the correct answer, and an explanation that covers both correct and incorrect choices. That last part is what separates a useful question bank from a quiz. When you get something wrong, the explanation tells you why the wrong answer was tempting and what the right reasoning looks like. The app also includes instructional text and illustrations, plus references for further study when you want to go deeper than the question itself.

The publisher describes this topical approach as a way to promote understanding and aid recall, and that is the right frame for it. Reading a regulation in isolation is forgettable; missing a question about it and then reading the explanation is not. The mix of text, illustrations and references gives you somewhere to go when an explanation raises a further question.

Practice tests and graded review

The second half of the study loop is the practice test. You can take a true-to-form test rather than only working question by question, and afterward you review the graded result. That cycle, test then review, is how you find out whether the subject study actually took hold.

I like that the review is built into the flow. A practice test on its own tells you a score; a graded test you can go back through tells you which subjects are still shaky and sends you back to the relevant chapter. Students preparing for a written exam tend to cycle between these two modes, and the app supports both without forcing one order.

The recent update is worth noting for anyone weighing an older copy of the material. Questions, answers and explanations have been refreshed to reflect the most current information available for the FAA Knowledge Test, which is the kind of maintenance that matters in a field where regulations and airspace procedures change.

What it costs and what that buys

The app is a one-time $4.99 purchase. There are no ads, and there are no in-app purchases, so nothing inside the app asks you for more money.

Set against the cost of a ground school course or a stack of printed study guides, five dollars is a small line item in the budget for earning a certificate. The comparison that matters more is time: a question bank is only worth paying for if you actually work through it, and the explanations are the part that justifies the purchase over a free set of sample questions.

One practical point the developer makes is that no internet connection is required, because the app fully installs to your device. For someone studying on a lunch break, in a hangar with poor signal or on a long drive as a passenger, that removes a real obstacle. It also means the study material is available wherever you happen to be.

How it compares with other ways to prepare

The alternatives fall into a few broad categories. A formal ground school course gives you an instructor, a schedule and classmates, at a much higher cost and with fixed times. Printed study guides and question books cover similar material, often from the same publishers.

Free question sets exist online, and they can be a reasonable starting point. A dedicated test-prep app trades that uncertainty for a known question set and a known publisher.

Where this app sits is in the middle: more structured than a free quiz, cheaper and more portable than a course. The trade-off is that it is narrow. It prepares you for one exam. That narrowness is a feature if the exam is what you are facing.

A focused tool for a specific exam

Prepware Remote Pilot UAS has been on Google Play since July 2016 and has been updated as recently as August 2026, with more than 10,000 installs and a 4.3 average from 164 ratings. Those numbers describe a modest, steady audience rather than a mass-market hit, which fits a niche exam-prep title.

My read is that this is a sensible purchase for anyone with a Remote Pilot knowledge exam on the calendar. The subject-by-subject structure, the explanations and the graded practice test cover the full study loop, and the $4.99 price with no ads or purchases keeps the decision simple. If you are working through a training program, it slots in as the question practice alongside whatever instruction you already have.

For a licensed pilot adding a drone rating or a self-study applicant building knowledge of commercial UAS operations, the same logic holds. The app is not trying to be more than a preparation tool, and for the exam it targets, that is enough.
