What’s new
Version 2.2 · Updated July 28, 2026
What's new in 2.2 • AcoustioNary is now FREE to download. The no-ads / no-tracking / data-stays-on-device stance is unchanged. • Choose your native language and learn English from your own language: Korean, Simplified & Traditional Chinese, Latin American Spanish, Brazilian Portuguese, Indonesian, Thai, Vietnamese, French, and Arabic. • Revamped English-immersion mode: in English, you see the English word, its English definition, and an English example. • Spaced Repetition: every "Got it" tap pushes the card further into the future; missed cards come back sooner. The Study tab now serves up the next-due card in order, so the buttons finally feel like they're doing something. • A large set of advanced "guitar-world" vocabulary — lutherie, tonewoods, setup, recording, technique, and music-theory words that guitar lovers will recognize. • New Expression Companion: begin with a real musical moment, explore nearby emotional nuances, rewrite the English in your own voice, and build a natural conversation turn. Your Personal Expression Library stays on-device. • Small Study-card layout polish so long headwords and phrases fit on one line. • Optional Tip Jar to support development — tips don't unlock anything; just a heartfelt thank-you. To everyone who bought the paid version: thank you. Onwards, in the guitar world.
