## What is Rhythm Perfector?

Rhythm Perfector is a practice app for reading rhythm notation and playing it accurately.
Read the score, then tap the pads after a one-bar count-in. You'll see how many milliseconds early or late every single note was.
Made for band, drum, piano and other instrument players, and for music students practicing rhythm reading for lessons and exams.

- Notation like school rhythm sheets
Two-hand rhythms on a single line: tap the notes above the line with your right hand and below it with your left. Black notes on white paper, easy to read.

- 72 levels, step by step
• Six stages: quarter notes, eighth notes, rests, sixteenth notes, dotted notes, triplets
• Tempo rises each time you finish the six stages (70 to 120 BPM)
• Levels 1–36 are right hand only, levels 37–72 use both hands
• Score 80 or more to pass and unlock the next level
• A new exercise is generated every time, so you can't just memorize it

- See every note's timing
• Perfect / Good / Miss shown on each note in color
• Timing in milliseconds (+ late, − early)
• Your early or late tendency for each hand

- Example playback and metronome
• Listen to the example before you play (right hand high, left hand low)
• The current bar is highlighted while you play (turn it off to practice like a real exam)

- Find your weak spots
• Levels passed
• 14-day trend of your average score and timing
• Patterns to work on (most misses and largest timing errors first)
• Best score for each level

- Calibrated to your device
Tap 16 times along with the beat, and the app corrects for your device's audio and touch delay. Recalibrate any time in Settings.

- Choose your strictness
Easy (±60ms), Normal (±40ms) or Strict (±25ms).

- Also
• Five color themes (Dark, Light, Blue green, Midnight, Warm)
• Adjustable metronome and example volume
• English and Japanese

Note: Bluetooth earphones delay the sound, so the device speaker or wired earphones are recommended.
Free to use, with ads.
