StringKeeper vs Classical Guitar Suite

Never wonder when you last changed your strings again. StringKeeper helps guitarists track string installations across every guitar in their collection, so your instrument always sounds its best. Track Every Guitar: Add all your guitars with photos, names, and notes. See at a glance which ones are due for a string change and which were recently restrung. Log String Changes: Record the string brand, gauge, and date every time you restring. StringKeeper tracks your history so you can see what worked and what didn't. Get Reminded: Set a reminder after a string change and StringKeeper will notify you when it's time to restring — no more playing on dead strings. Log Play Sessions & Maintenance: Track how often you play each guitar and log maintenance records to keep a full history of each instrument. If you notice a guitar has dead strings you can set a "Needs string change" flag which will cause an alert icon to appear next to the guitar. Pick a Guitar to Play: Not sure which guitar to pick up tonight? Use the slot machine to let StringKeeper choose for you.

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].
