Language learning made easy for busy people with Pecto! Pick your language — Finnish, Swedish, or English — and learn it from your own language, with a clear path matched to your level and goal. Learn in the car, during chores, or whenever you have a free moment, thanks to two powerful modes: • AUDIO MODE: Listen to a personalized audio stream of words and phrases you need to review, plus new vocabulary to grow your skills—perfect for learning on the go when your hands and eyes are busy. You can also give feedback hands-free: mark words as easy or hard directly with your car steering wheel buttons (next/back) or headphone taps (double/triple-tap). This way, Pecto adapts to you even when you’re driving or walking with your phone in your pocket. • CARDS MODE: Practice with interactive flashcards. Swipe up for easy words, swipe down for challenging ones—our spaced repetition system does the rest. No extra setup is required; the most important cards are ready to go! Choose your language and goal • FINNISH: Structured around the first three Suomen Mestari textbooks — 5,000+ words, enough to prepare for the YKI test and reach up to B2 proficiency. • SWEDISH: Follows the Rivstart A1+A2 textbook, the proven path for beginners. • ENGLISH: Pick the goal that fits you — General English from A0 to B1, Cambridge B2 First, Cambridge C1 Advanced, IELTS (General or Academic), or SAT/GRE/GMAT vocabulary — and get exactly the chapters you need. Key Features of Pecto • Learn from your own language: English, Russian, Arabic, and more, depending on the course. • Free words in every language to get started; unlock the full vocabulary with a subscription. • Practical Phrases and Examples so you learn in context, not as isolated vocabulary. • Full Audio Support with authentic native-sounding voices for natural listening. • Hands-free feedback support in Audio Mode with car steering wheel buttons and headphone controls. • FSRS-based spaced repetition algorithm, built on modern memory science and more accurate than traditional models. Helps you remember words longer with fewer unnecessary reviews. • Switch languages anytime — your progress, chapters, and streak are saved separately for each one. Perfect for anyone who wants to learn a language quickly and effectively, especially if you have limited study time. Pecto is also an excellent alternative to Anki, Memrise, Reword, Quizlet, and Duolingo if you prefer audio-based learning. Start learning with Pecto today and experience how easy it is to fit language study into a busy life! Terms: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
