## What is Guitar Theory Studio?

Guitar Theory Studio puts music theory on the fretboard: guitar scales and modes, the CAGED system, chord progressions with smooth voice leading, arpeggios, ear training, and a daily theory quiz, all computed by one theory engine and drawn on a physically accurate neck.

EVERY TOOL IS FREE
Explore any guitar scale, key, or CAGED shape on the Fretboard Explorer. Build and hear progressions with smooth voice leading in the Chord & Progression Builder — with a library of 25 classic progressions, every chord numbered in both Nashville Number System notation and Roman numerals. Sweep arpeggios for every chord in a key. Drill every 7-note scale in its seven three-notes-per-string (3NPS) positions, plus the pentatonic boxes, with the metronome-driven Practice Loop — a tempo ladder climbs as you play and remembers your best — or start guided practice and it walks you through every position, timed, hands-free. No account needed.

THE DAILY — A MUSIC THEORY QUIZ FOR GUITAR
Ten quick questions a day — read the neck, know the key, trust your ear. Same puzzle for everyone, new one at midnight, and a streak that grows every day you show up. Miss a question and it teaches you the answer. Turn on the morning reminder and the app tells you when tomorrow's puzzle is ready. Interval and chord-quality questions double as ear training. Tap Test Me inside any tool for five questions about exactly what is on screen.

ASK — AI THAT SETS UP THE TOOL FOR YOU
Type a question like "show me D Dorian" or "a 12-bar blues in E" and the right tool opens, already set up. The AI only picks the tool and settings — every note and spelling is drawn by the same theory engine as the rest of the app, so the answer on the fretboard is always right.

GTS PRO — YOUR PERSONAL THEORY TRAINER
Personalized daily workouts built from what you miss, and daily practice plans that pick the loops you should run next — your slowest position, the one you haven't played, the one to push. Mastery levels for every skill, revisited on schedule just before you'd forget. Full progress history with practice-time tracking and your best tempo per position. Unlimited Test Me, expanded Ask, unlimited saved presets. GTS Pro is a monthly or yearly subscription with a 7-day free trial, or a one-time lifetime purchase — manage or cancel anytime in your App Store account settings.

Notes and chords are spelled the way the key is actually written — B flat in F major, not A sharp — so what you read here matches what you read anywhere else.

Whether you're learning your first guitar scale or building a music theory practice routine that actually sticks, Guitar Theory Studio keeps theory and the fretboard in the same place.

## Version history (last 5 releases)

### 1.3.3 — 2026-09-11

• Morning reminder: turn it on after any Daily and the app tells you when tomorrow's puzzle is ready.
• Today's loops: a ten-minute practice plan built from what you've played and how fast — your slowest position, the one you haven't played, the one to push. First plan free.
• The tempo ladder: the Practice Loop climbs as you play and remembers your best tempo per position.
• Play it in 3rds: pick a scale on the Fretboard, hear every note with its harmony partner, then loop it.
• A fairer Daily: ear questions wait until you've listened, and the run opens on the neck.
• GTS Pro Lifetime: pay once, keep Pro for good.

### 1.3.2 — 2026-09-05

A cleaner way to go Pro: plan cards with the price up front, one button, and a free-vs-Pro table. A tidier Account screen. The Daily leads with Start and reads the date properly. Ask can harmonize a scale ("harmonize G major in 3rds"). Plus fixes across Fretboard, Chords, Arpeggios and Practice, and the app now asks for a rating after a good run — once, and only if you've been back.

### 1.3.1 — 2026-09-04

• The Daily's results screen now shows where you struggled most and what tomorrow's workout will drill.
• Share your daily score grid with friends.
• Practice Loop and Arpeggios controls tidied up: tuning options sit under the fretboard, and Extension sits beside Type.

### 1.3.0 — 2026-08-31

The Daily is here. Ten quick questions every day — read the neck, know the key, trust your ear. Same puzzle for everyone, new one at midnight, and your streak grows for every day you show up.

Test yourself inside every tool. A new Test Me button quizzes you on exactly what is on screen — your key, your scale, even the progression you just built.

Three challenges, every day. Play the Daily, complete a Test Me on every tool, ask one question — the checklist tracks all three and knows a perfect day when it sees one.

Meet GTS Pro — your personal theory trainer. Personalized daily workouts built from what you miss, mastery levels for every skill, and your full progress history.

Arpeggios and the Practice Loop are now free for everyone — and the Practice Loop gains guided timed practice: pick minutes per position and it walks you through every position of the scale, hands-free.

Miss a question and it teaches you the answer. String a few days together and the app starts showing you what's worth practicing.

### 1.2.1 — 2026-08-25

• Fixed: Ask now answers your questions in the app
• Shared links open smoother, with the full setup visible
