What's New in NashvilleTrainer

2.2.0

August 25, 2026

Practice Plans: guided day-by-day curricula with a clear goal. Start free with Number System Foundations, seven days to stop translating and start thinking in numbers. Pro adds Ear Training Bootcamp, Own the Key of E, and Sunday Ready. Song Mode (Beta): add the songs YOU play as number charts, verse and chorus and bridge, and get quizzed on them. Spell each section in any key, name the chords inside it, transpose it on the spot. Share a song and a friend imports it with one paste. It's brand new, so there's a Send Feedback button right in it. Free includes one song; Pro unlocks your whole set list. New Master difficulty: everything from Advanced plus extended qualities, the sus, sus2, maj7, m7, and 7 chords worship actually runs on. New Extended Qualities drill: see 4(2), 5sus, 1maj7, or 6m7 in a key and name the chord, or the reverse. Beat the Clock: an optional timer in MD Mode. Answer each call in seconds, like a real service. Streak milestones: hit 7, 30, or 100 days in a row and the app celebrates with you, and hands you a card worth posting. Streak Protection: an optional evening alert that only fires when your streak is about to break and you haven't practiced yet. Tell a Friend: share the app with a link or a card from Settings, or the next time you finish something worth bragging about. Recent Accuracy on Home now means it: your last 100 answers, not your lifetime average. The rating prompt now waits until you tap Done, so it never interrupts a flawless-session celebration. Answer feedback and streak milestones are now announced for VoiceOver. Smoother over long sessions: fixed the animation slowdown that crept in the longer you practiced, plus faster question generation on big practice histories.
