KingMetronome VS React-Ionic

KingMetronome's answer

KingMetronome is not a metronome — it's a complete rhythm laboratory with 13 specialized modules. Each module trains a specific skill that standard metronomes can't touch:

◆ BASE METRONOME — Sample-accurate click with custom subdivisions, accents, and time signatures ◆ RHYTHM READER — Sight-read infinite generated patterns in real music notation (VexFlow). 376 rhythmic combinations from quarter notes to sextuplets and quintuplets ◆ CLAVE BUILDER — Son, Rumba, Afro 6/8 and custom claves in any subdivision. Build your own claves for any style ◆ NEGATIVE SPACE — The click disappears for 1, 2, or 4 bars. Can you hold the tempo alone? This is how you build an internal clock that doesn't need a crutch ◆ POLYRHYTHM TRAINER — Master 3:2, 4:3, 5:4, 7:5 and any cross-rhythm ratio with integrated phrase sequencer ◆ METRIC MODULATION BUILDER — Create custom tempo equivalences with drag & drop (quarter = dotted quarter, triplet = sixteenth, any equivalence). Unique feature not found in any other app ◆ GROUPS (Additive Rhythms) — Practice 4+3, 3+3+2, 5+3 against 4/4. Hypnotic, addictive, essential for odd meters ◆ DISPLACE — Shift a pattern across the beat. What was on 1 is now on the "e" of 2. Mind-bending practice for fills and polyrhythmic independence ◆ BINARY TO TERNARY ADAPTATION — Interpret binary phrases over sextuplets. Explore the 4↔6 conversion and feel how the groove changes while keeping the pulse ◆ TIMING TEST — Measures your precision down to the millisecond. No more guessing if you're rushing or dragging ◆ TAP TRAINER — Auto-progression mode with BPM ramping. Stick mode and audio pre-warm for tactile practice ◆ ELASTIC PHRASE — Shift phrases ± subdivision. Train independence by moving patterns over the base pulse ◆ POLYMETER — Combine 9/8 + 4/4, create irregular sequences, and practice with total pulse control

WHY IT'S A LABORATORY, NOT A METRONOME:

A laboratory is a place where you experiment, measure, and develop new skills systematically. KingMetronome works the same way:

→ Each module isolates a specific rhythmic skill (timing, polyrhythm, modulation, reading, internal pulse) → You can measure your progress (Timing Test gives objective millisecond precision) → Modules combine into guided routines for structured practice sessions → Built around the philosophy that a metronome should train you, not just click at you

Built by Martin Moroni, a working drummer who designed every module based on real practice needs — not on what looks good in a feature list.

KingMetronome's answer

Three reasons:

1. Depth of practice tools: 13 modules vs the 1-3 basic features of most metronome apps. KingMetronome covers polyrhythms, metric modulation, sight-reading, displacement, additive rhythms, claves, and more.

2. One-time payment, no subscription: $6.99 USD for lifetime access. Most modern metronome apps charge $5-10 per month.

3. Built by a musician, not a developer: the creator is a professional drummer who designed every feature based on real practice needs — not on what looks good in a feature list.

It's the metronome that actually teaches you something.

KingMetronome's answer

Serious musicians who want to develop real timing skills:

• Drummers and percussionists obsessed with time and groove
• Jazz musicians working on metric modulation and odd meters
• Latin musicians studying clave patterns and Afro-Cuban rhythms
• Music students and teachers using it as a practice tool
• Guitarists and bassists who want to develop independence and polyrhythmic awareness
• Composers and producers working with complex rhythmic structures

The common thread: people who've outgrown basic metronomes and want a real practice tool.

KingMetronome's answer

Created by Martin Moroni, an Argentine drummer based between Belgium and Argentina. After 20+ years of drumming and frustration with metronome apps that only click, he started building tools for his own practice — polyrhythm trainers, metric modulation builders, sight-reading generators.

Over 2 years, those tools became 13 connected modules covering every aspect of rhythm training he wished existed. Released publicly in 2026 on iOS and web.

The philosophy: a metronome should train you, not just click at you.
