Meet Tenney: a ratio-first tuner and lattice for musicians who work in just intonation. SEE INTERVALS INTUITIVELY • Live pitch readout with pro-grade metrics and complications • ± cents vs 12-TET and live Hertz • Confidence readout to judge stability • Adjustable root (e.g., 415 or 440 Hz) and prime-limit EXPLORE a LIVE LATTICE • 3×5 plane with pinch-to-zoom and smooth panning • Tap to focus any node: p/q, ±¢ vs ET, and Hz at a glance • Prime-overlay chips (7, 11, and beyond) to reveal higher-prime families • Axis Shift ribbon (±3/5/7/11) to slide the lattice musically MADE FOR THE WAY JI MUSICIANS THINK • Ratio-centric labels with proper oddization • Prime-limit control (3/5/7/11/13+) • Strictness options for detection behavior (Loose / Performance / Strict) • Designed to feel immediate, informative, and stage-safe THOUGHTFUL BY DEFAULT • Works offline; no accounts, no ads • Light and Dark modes, portrait and landscape • Fast, fluid UI with Apple’s latest glass effects where available WHAT’S IN THIS VERSION • Core tuner with ratio labels, cents vs ET, and confidence • Lattice v0.3: explore, overlay chips, axis shifts, selection tray • Practice timer and root-following test tone WHO IT’S FOR • Performers and composers working in just intonation • Ear-training, rehearsal, and structural exploration of JI spaces • Anyone curious about harmonic relationships beyond 12-TET SUPPORT Questions or feedback?
