Play any song in any key. Nashville Trainer teaches the Nashville Number System, the language worship teams and session musicians use to call chords as numbers. Instead of memorizing chords for every key, you learn to think in numbers. Once it clicks, you can read a number chart, follow the band, transpose on the fly when the leader changes key, and play by ear with confidence. WHAT YOU GET • Visual drills that connect numbers to chords and back • Ear training to recognize chords and progressions by sound, with a Slower button when you need it • Song Mode (beta): chart your set list as numbers with the words, paste a chord sheet or ChordPro file, read it in any key, and share it with your band • Practice Plans: guided day-by-day paths with a clear goal • A Daily Challenge that changes every day • An interactive fretboard and keyboard to see the numbers in any key • MD Mode, which simulates a music director calling changes on a Sunday morning, with an optional Beat the Clock timer • Expert Mode, where you build every chord by hand with no multiple choice • Extended Qualities: sus, maj7, m7, and the other color chords worship runs on • Progress tracking with accuracy, streaks, and focus areas • Practice reminders, plus Shortcuts and Siri phrases to jump right in • Multiple instrument sounds and color themes BUILT FOR WORSHIP MUSICIANS The app uses the real conventions worship teams rely on, including the 5/7 walk-up that players use in place of the diminished 7. Guitar, keys and bass players all practice the same numbers on their own instrument. FREE TO START Six core practice modes are free forever, along with the Daily Challenge, your first song in Song Mode, and the starter Practice Plan. Upgrade to Pro once (no subscription) to unlock all twelve keys, Keys and Bass modes, Intermediate, Advanced, and Master difficulty, MD and Expert modes, Extended Qualities, unlimited songs, every Practice Plan, Key Practice, the full stats dashboard, progress sharing, and every theme.

SMARTER PASTING • Put My Chords on These Words lands more of your chords on the right words, in the song's order, without losing anything you've entered. • Pasted charts read better. Headings like Intro, Tag and Refrain and notes like "Drums in" come across as they should, and a chord sheet pasted into a new song sets the song's key from its chords. BUG FIXES AND POLISH Streaks, charts and today's progress hold steady across midnight and daylight saving changes, time away from the app no longer counts as practice, and everything works better with VoiceOver and the largest text sizes. Thank you to everyone who sent feedback. Every note gets read, and it shapes what gets built next. Want a say in what comes after this? Join the Nashville Trainer user group from Settings, then About. ### 2.3.0 — 2026-09-23 SONG MODE TAKES LYRICS Paste the words to your song and the app splits them into sections. Tap a word, tap a number, and the chord sits above it, the way a chart is written by hand. Chord sheets and ChordPro files come across as numbers automatically. View Chart reads a song back from the music stand, in numbers or letters, in any key you pick, with the screen staying awake. Share a chart with your band in a tap. Your lyrics never leave your device. MORE WAYS TO WRITE A CHART • Slash chords: the 1/3, the 4/1, the 1/b7 • Chords before a word or between two words • A note for the band beside a section's name • Sections in any order, by drag or arrows • Up to 24 sections a song ALSO NEW A fresh look in both Light and Dark Mode, a user group where you can ask questions and vote on what gets built next, and a long list of fixes: every chord kept when you paste a chart, charts that open in your song's key, and ear drills that tell you when Audio is off. Thank you to everyone who sent feedback. Most of this came straight from you. ### 2.2.1 — 2026-09-21 NEW FEATURES: • Sharps and flats in Song Mode. Chart the chords that live outside the key, like the b7 (F in the key of G), b6, b3, b2, the minor 4, and sharp passing chords like the #4. They show up in your song quizzes too. • Letters entry. Still learning your numbers? Switch the chart builder to Letters, tap the chords straight off your chord sheet, and watch each one turn into its number. • Shortcuts. Press and hold the app icon to jump into the Daily Challenge, pick up where you left off, or open My Songs. The same actions are in the Shortcuts app and Spotlight, and Siri runs them when you say a set phrase like "Start my Nashville Trainer daily challenge." Smarter, more conversational Siri support is coming soon. • Slower is now available before you answer, not just after. • A refreshed look with Liquid Glass controls, a tab bar that tucks away while you scroll, and sheets that fit their content. • Expert mode has a / key, so you can build the 5/7 the way it's written: D/F#. • My Songs: each song has a menu for Edit, Share, Duplicate, and Delete, and deleting asks first. • Tapping a practice reminder opens today's Daily Challenge, and the session that finishes your daily goal celebrates it. • Finished Practice Plans can be run again. • New in Settings: Auto-Advance When Correct, and a switch to turn off the key signature hint (you can also turn it off from the hint itself). BUG FIXES: • Ear training is easier to hear. The key is set by a soft root note that no longer overlaps the last question, and each chord is held long enough to really hear it. • Playing notes or progressions quickly on the Guitar, Keys, and Bass tabs no longer makes the sound crackle. • The key signature hint no longer nudges the question up the screen. • Layouts fit better on smaller iPhones and with large text, right and wrong answers are clearer in Light Mode, and VoiceOver reads chords the way musicians say them. • The second fretboard page is labeled with the right frets, the Keys 5/7 lists the right notes, Stats names every focus area, and the same key can't show up as both strongest and weakest. Thank you to everyone who sent feedback. Many of these changes came straight from you. ### 2.2.0 — 2026-08-25 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. ### 2.1.1 — 2026-07-01 What's new in 2.1.1: - Daily Challenge: a new once-a-day drill on the Home screen. Finish it to build your daily-challenge streak, with a different mode each day. - Practice Weak Spots: a one-tap session that zeroes in on the key you've been struggling with most. - Daily practice reminders: pick a time in Settings and we'll nudge you, with a message tailored to what you're nailing or working on. - Play Again right from your results, plus an end-of-session recap showing what you answered, the correct answer, and why. - A new Number System glossary in Settings, under Learn, for quick reference. - Correct and incorrect answers now show a clear check or X mark, not just color, so they're easier to read. - Ear training now lets the key reference settle fully before the chord plays. - Lifetime stats, a per-mode help button, a What's New screen after each update, and a streamlined Advanced mode. ## Apps similar to Nashville Trainer | App | Rating | Price | Category | | --- | --- | --- | --- | | [WorshipU-New](https://appshunter.io/ios/app/worshipu-new/id6751707374) | 5.0 (1) | Free | Education | | [The Unhindered Voice Hub](https://appshunter.io/ios/app/the-unhindered-voice-hub/id6744654949) | 4.6 (11) | Free | Education | | [Fretionary](https://appshunter.io/ios/app/fretionary/id6761344883) | 4.6 (25) | Free | Education | | [MxU](https://appshunter.io/ios/app/mxu/id6448795537) | 4.5 (17) | Free | Education | | [Grokit: Guitar & Music Theory](https://appshunter.io/ios/app/grokit-guitar-and-music-theory/id6472812202) | 4.4 (60) | Free | Education | | [Music Theory by Justin Guitar](https://appshunter.io/ios/app/music-theory-by-justin-guitar/id6747342863) | 4.8 (391) | Free | Education | ## Related topics [nashville numbers](https://appshunter.io/ios/topics/nashville-numbers) · [transpose youtube](https://appshunter.io/ios/topics/transpose-youtube) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
