Polytactus Metronome
Polyrhythm & subdivision beats
$1.99 · Designed for iPad. Not verified for macOS.
Mix every layer of the beat — quarters through 16ths, triplets, and custom tuplets from 2 to 16. One purchase. No ads or subscriptions.
Polytactus Metronome is a precision metronome built around one idea: hear every layer of the beat at once.
MIX YOUR SUBDIVISIONS
Six independent click tracks — accent, quarter, eighth, sixteenth, triplet, and a free n-tuplet (2–16) — each with its own volume slider and tone. Blend quarters with triplets, add a 5-tuplet on top, or isolate just the accents. Your rhythm, your mix.
BUILT FOR REAL PRACTICE
• Tempo 30–300 BPM: dial, ± buttons, direct number entry, or tap tempo
• Time signatures from 1/2 to 16/16, with automatic compound-meter accent grouping
• A/B alternation: assign each track to A beats, B beats, or both to build alternating patterns
• Count-in and auto-stop after a set number of bars
• Visual mode: a swinging needle and screen-edge pulse you can follow with sound off
CLEAN, FAST, YOURS
• Full-screen layout in portrait and landscape, on iPhone and iPad
• Interactive tutorial that walks you through every control
• Light / dark themes and custom accent colors
• All click tones are synthesized in-app — no samples, instant start
• Optional haptic feedback, controlled in Settings
• Keeps clicking in the background while you use other apps
ONE PURCHASE, EVERYTHING INCLUDED
No ads. No subscriptions. No in-app purchases. Buy once, practice forever.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Bug fixes and refinements:
• Fixed haptic feedback firing ahead of the click — the tap is now aligned to the audio output latency of the current route, so touch and sound land together
• Removed a per-click audio-session call that could add timing jitter
• Haptic feedback now starts switched off on new installs; turn it on any time in Settings (existing settings are kept)
• Feature tips no longer appear on top of the first-launch tutorial — they now wait until the tutorial is finished
• The Tap circle at the bottom of the dial now takes the accent colour when a beat sounds there, matching the −/＋ marks
• The metronome settings window now uses the same rounded card shape as the general settings screen
• Corrected Traditional Chinese text in the tutorial and demo captions
