Complete theory preparation for the EASA Sailplane Pilot Licence (SPL) — bilingual Polish/English, fully offline. More than a question bank: each of the 133 lessons teaches first and tests second. 487 original questions with explanations cover all 9 exam subjects per EASA Part-SFCL (AMC1 SFCL.130): • Air Law • Human Performance • Meteorology • Communications • Principles of Flight • Operational Procedures • Flight Performance & Planning • Aircraft General Knowledge • Navigation TEACHES, NOT JUST TESTS Every topic is a concise lesson with key points, followed by practice questions with instant explanations — you understand why an answer is correct. EXAM SIMULATION A random paper at the official AMC1 SFCL.135 length (e.g. Air Law: 20 questions / 40 minutes), scored at the end with a 75% pass mark — just like the real exam. REVIEWS THAT WORK Built-in spaced repetition brings questions back exactly when you start forgetting them. A daily streak keeps you regular. YOUR PROGRESS AT A GLANCE Progress (how much you have mastered) and exam readiness (how durably you remember it) are tracked separately. Mock-exam history, per-subject breakdown and a "what's left" counter. TWO LANGUAGES, NO INTERNET NEEDED All content in Polish and English — switch with one tap. Everything works offline, and progress syncs via iCloud between your iPhone and iPad. No account. No ads. No data collection. Note: this app is a study aid — it does not replace training at a certified organisation or official EASA/CAA materials.
