Classical Guitar Suite vs Classical Guitar Tools

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].

Classical Guitar Tools is the complete toolkit for the serious guitarist: a precision chromatic tuner, a stage-ready metronome, acoustic string-health diagnostics, a sheet-music library, and an AI technique coach — all in one beautifully crafted app. CHROMATIC TUNER Fast, accurate tuning with tone alignment and one-tap reference tones from low E to high E. Play the reference tone from Control Center or ask Siri — perfect for ear training. PRECISION METRONOME Every time signature from 2/4 to 7/8, with crisp audio ticks or silent haptics you can feel. On Apple Watch, turn the Digital Crown to dial in the tempo without missing a beat. ACOUSTIC STRING HEALTH Pluck three times and see how each string measures against its own fresh-string baseline. Track sustain, early high-frequency response, and retention over time, so you know exactly when it is time to restring. SHEET MUSIC Import your scores as PDFs from Files or any app with the share sheet, and your library syncs to your private iCloud. Read in a dark, music-stand-friendly view, annotate directly on the page, and pick up right where you left off. AI TECHNIQUE COACH Snap a photo of your playing position and get severity-rated feedback on posture, wrists, and hands, with exercises you can try right away. The photo is erased immediately after analysis. PRIVATE BY DESIGN Tuner, metronome, and health measurements run entirely on your device. No audio is ever recorded or stored. Your sheet-music library lives in your private iCloud. See it. Measure it. Master it.
