For too long, metronomes have made practicing tuplets hard and clunky. ORhythmic turns traditional click-tracks into interactive rhythmic trees, allowing you to create structures previously confined to your innermost thoughts. Top features: - Near unlimited nested tuplets at the click of a button. - Intuitive edit controls without diving into complex menus. - BPM controls from 1 to 500. - Time signatures from 1/1 to 100/100.

About

Calcophony

Features
Read full description

Calcophony is a scientific calculator for composers and musicians. It handles the mathematical side of music composition, from tempo and metric modulation to tuning systems, just-intonation ratios, polyrhythms, spectral analysis, and spectrograms, plus a metronome and a chromatic, instrument-aware tuner. TEMPO MODULATION CALCULATOR Enter a starting tempo to compare note-value reinterpretations in a BPM matrix, with near-integer results highlighted. Adjust tolerance, tuplet complexity, and target-BPM matching. METRIC MODULATION PLANNER Bridge distant tempos in multiple steps, with optional ordered intermediate tempos and pivot note values at each transition. Compare paths and target deviations, with closest alternatives when no path meets your tolerance. Adjust maximum steps and tuplet complexity. RHYTHM & SUBDIVISION CALCULATOR Calculate tuplets and nested groupings, with per-note durations in milliseconds, total duration, and equivalent note-value groupings. POLYRHYTHM VISUALIZER Audition two or more pulse streams over a base tempo. See attack points, coincidences, and numbered composite patterns. Choose nested polygons, polygons on one circle, or rings. Mute or solo streams with distinct click timbres. FREQUENCY & PITCH CONVERTER Convert between Hz, pitch name, MIDI note number, and cents. Set your reference pitch and audition the current pitch. HARMONIC SERIES EXPLORER Explore harmonic or subharmonic series from any fundamental. See each partial's frequency, nearest pitch, and cents. Highlight interval and chord families, audition one or many partials, and play them from a grand staff. INTERVAL & TUNING CALCULATOR Enter an interval by name, ratio, or cents. Approximate cents values with just-intonation ratios under a selectable prime limit, up to 31. Compare 12-TET neighbors and cents deviations. Set a root pitch to see beat frequency. RATIO CALCULATOR Multiply, divide, and raise just-intonation ratios to powers using exact arithmetic. See simplified fractions in full register and octave-reduced, with decimal and cents values. Audition intervals together or in sequence. Stack twelve fifths to reveal the Pythagorean comma. SPECTRAL CALCULATOR Compute sum, difference, Tartini, and second-order combination tones. See reinforced tones and implied bass fundamentals whose harmonic series fits your inputs. SPECTROGRAM ANALYZER Import audio or record from the microphone, then explore its frequency content with pinch-to-zoom and pan. Select a time to inspect partials, audition them from a grand staff, and find the implied fundamental. Share analysis as plain text. DURATION CALCULATOR Generate note-value duration tables in milliseconds and MM:SS.mmm, with an optional offset for scoring and session work. Enter a duration to solve for tempo or find the closest standard note value. METRONOME Use common and asymmetric meters, ten sound sets and a silent mode, custom accents, subdivision clicks, tap tempo, count-in, and tempo ramping. Share your setup as plain text. TUNER Detect pitches down to A0, with presets for guitar, bass, violin, viola, cello, double bass, ukulele, mandolin, and banjo. Choose alternate tunings including Drop D, DADGAD, and Open G. Switch between meter and strobe views and adjust tolerance. Explore Werckmeister III, Kirnberger III, Vallotti, Young I, quarter-comma meantone, and Pythagorean temperaments. Set reference A4, play per-string reference tones, and transpose instrument tunings by semitones. Share settings and readings as plain text. --- Free tier includes Tempo Modulation, Frequency & Pitch, and the Metronome. A 7-day free trial unlocks every module. A single one-time purchase unlocks everything permanently, with no subscriptions.

Verdict

The call

The clearest difference is in-app purchases: ORhythmic at none against Calcophony's 1. ORhythmic also leads on update cadence (every 2 weeks vs every 6 weeks). On price, ads, device support and iOS requirement there is nothing between them.
