Meteorology101 vs KnowTAM

Get your head in the clouds! Meteorology 101 turns weather science into something you can learn, practice and play, whether you're a student, a pilot, a weather spotter, a future forecaster or just someone who loves a good storm. STORM CHASE GAME Hit the road in your chase vehicle and race toward a building supercell. Every correct answer brings you closer to the storm. Wrong answers bring hail cores, flooded roads, flat tires and road closures that burn your fuel and push you back. Reach the storm before it falls apart, and before your tank runs dry, to capture the tornado on camera. Each chase day starts farther away and gets tougher. Choose any topic, or mix them all.

Pass your FAA written and your checkride oral with one app. KnowTAM has 1,800+ flashcards, quizzes, practice exams, and oral-exam sets, written and reviewed by a working CFI. Start free. Pay once. Never a subscription. UPDATED FOR THE NEW INSTRUMENT QUESTIONS From October 26, 2026, the FAA's Instrument test adds image-based questions built on current sectional, approach, and low-altitude en route charts. KnowTAM's Instrument deck has 24 new cards on current FAA chart excerpts, so you practice reading them before test day. WHY PILOTS PICK KNOWTAM • Every card explains the "why," not just the answer, with the regulation or handbook reference and the exact FAA ACS code it covers. • Quizzes show why each wrong answer is wrong. • Real FAA figures: sectionals, instruments, approach plates, airport signs and markings, weather diagrams. • Timed practice exams built like the real test, scored against the 70% passing mark. Private exams follow the FAA subject blueprint. • Checkride and oral-exam sets that drill the way a Designated Pilot Examiner asks. Great before a flight review, too. A PLAN THAT GETS YOU THERE ON TIME Enter your rating and test date. KnowTAM sets each day's new cards and reviews, shows whether you're on track, and tells you when to take a practice exam. Spaced repetition brings back what you miss and spaces out what you know. In the final week, your plan brings back anything you haven't seen lately. STAY WITH IT • A daily streak that counts the days you hit your plan. • Home Screen and Lock Screen widgets with today's study and your streak. • Optional reminders at the times you choose, only on days your plan isn't done yet, plus reminders the week of your test. KNOW WHEN YOU'RE READY • Readiness by area shows which subjects are ready, close, or need work, from your practice exams and cards. One tap quizzes the weak ones. • Practice sets for the cards you missed recently and the ones you saved. • After the test, tell the app how it went. Passed? On to your next rating. Didn't pass? Enter the ACS codes from your test report and practice exactly those. STUDY ANYWHERE Fully offline, even in airplane mode. No account required.
