## What is Classical Guitar Suite?

Classical Guitar Suite (CG Suite / formerly ReString Logger) is a comprehensive performance, practice, and instrument maintenance platform designed specifically for classical guitarists[cite: 1].

Note: This application has been rebranded from "ReString Logger" to "Classical Guitar Suite," introducing a fully featured sheet music reader alongside expanded acoustic practice and maintenance tools[cite: 1]. All existing string management, acoustic measurement, and tuning records remain fully supported[cite: 1].

--- Key Features ---

1. Sheet Music Reader (Score Reader)
- Fast PDF rendering with seamless page transitions[cite: 1].
- Flexible viewing options: Single page, two-page spread, and a 4-page overview grid[cite: 1].
- Apple Pencil and touch-friendly annotation tools: freehand pens, highlighters, text notes, and musical notation stamps[cite: 1].
- Bluetooth page-turner pedal support with repeat-guard protection[cite: 1].
- Linear sequence builder: set custom cut points to navigate repeats and Da Capo structures in a single direction without jumping back[cite: 1].
- Cloud synchronization via Google Drive to keep scores and annotations securely synced across devices (optional feature)[cite: 1].
- Floating mini-tools: view tuners or metronomes in a compact window over your score while practicing[cite: 1].

2. High-Precision Strobe Tuner & Acoustic Temperaments
- Multi-band phase-accumulating strobe display delivering sub-cent (0.1 cent) visual accuracy[cite: 1].
- Perceptual auto-snap: automatically distinguishes pluck attack transients from stable sustain to confirm true pitch[cite: 1].
- Guitar-specific temperaments: Key-optimized modes to eliminate 3rd-string beat beating, and Chord-optimized modes to compensate for fretting tension rise[cite: 1].
- Dyad Beat Tuning: objective guidance for traditional two-note harmonic and open-string beat listening[cite: 1].
- Automatic string detection across all six strings[cite: 1].

3. String Management & Guitar Specs
- Track days installed, playing hours, tension, and wear across your active guitars[cite: 1].
- Log detailed reviews, string tension specs, and tone profiles for each set[cite: 1].
- Manage inventory for complete sets and individual single strings[cite: 1].
- Comprehensive classical guitar string specification database and comparison tools[cite: 1].

4. Acoustic Diagnostics & String QA
- Objective string quality assurance: measure sustain envelopes, roundness beat modulation, and inharmonicity stiffness (B-coefficient) to detect defective strings[cite: 1].
- 12th-fret octave intonation comparison between natural harmonics and fretted notes[cite: 1].
- Guitar timbre analyzer: track spectral centroid, harmonic balance, and T30 decay times to compare tone evolution over time[cite: 1].

5. Technique Practice Analyzer & Recording
- Real-time analysis for tremolo (p-a-m-i), arpeggios, and alternating scales (i-m): measures strike timing evenness, finger volume balance, and brightness[cite: 1].
- Hands-free studio recorder: auto-arms to start on your first note and auto-stops on silence for instant loop review[cite: 1].
- Acoustic metronome with physical pendulum display and acoustic tempo detection from your guitar playing[cite: 1].
