What is the AdFreeApps Metronome?

Our free online metronome is a powerful practice tool designed for musicians of all skill levels. Whether you're a beginner learning to keep time or a professional musician practicing complex rhythms, this metronome provides everything you need without the distractions of advertisements or invasive tracking.

Unlike many other online metronomes cluttered with ads that interrupt your practice, our tool offers a clean, focused interface that lets you concentrate on what matters - improving your timing and musical skills.

Key Features

How to Use

Getting Started

• Start/Stop: Click the "Metronome" pulse or the Start/Stop button
• Set Tempo: Click the BPM number to open the tempo slider and quick presets
• Choose Sound: Select from the dropdown (Beep, Bass, Cymbal, Tock, Riffs, Vibrate, or Silent)
• Change Theme: Click the colored circle in the top-left corner

Visual Indicators

• Metronome (left pulse): Flashes on each beat to keep you in sync
• Your Beat (right meter): Shows your tapping/movement intensity in real-time
• Tap the "Your Beat" meter to enable/disable beat detection

Beat Detection Modes

Choose from three beat detection modes:

• No Beat Detection: Standard metronome - plays continuously
• Tap Beat Detection: Uses your device's accelerometer to detect taps/movements
• Audio Beat Detection: Uses your microphone to detect beats from your instrument (optimized for cello and violin)

How Tap Detection Works:

• Enable by selecting "Tap Beat Detection" from the dropdown
• The metronome runs silently while you practice
• Your device's accelerometer detects taps/movements
• The system evaluates both timing and tempo:
  • Timing: Are you within tolerance of the beat? (in milliseconds)
  • Tempo: Is your overall BPM within range?
• If you're on beat → Silent (green status)
• If you drift off → Metronome beeps to guide you back

How Audio Detection Works:

• Enable by selecting "Audio Beat Detection" from the dropdown
• Grant microphone permission when prompted
• Play your cello or violin - the app analyzes audio for beats
• Uses low-pass filtering optimized for string instruments
• Detects note attacks/peaks to identify beats
• Same on/off beat feedback as Tap Detection

Beat Detection Settings

These appear when Beat Detection is enabled:

• Beat Detection (0-100%): Motion sensitivity
  • Higher % = detects lighter taps
  • Lower % = requires harder hits
  • Default: 50%
• Timing Tolerance (5-1000ms): How precise your timing must be
  • 100ms = within 0.1 seconds of the beat
  • Lower = stricter timing required
  • Higher = more forgiving
• BPM Tolerance (0-20): How consistent your tempo must be
  • 5 BPM = stay within ±5 BPM of target (e.g., 115-125 when target is 120)
  • 0 = must match target exactly
  • Higher = more tempo drift allowed

Pro Tip: Focus on one skill at a time!

• Practice tempo consistency: Set Timing Tolerance to 1000ms (max)
• Practice precise timing: Set BPM Tolerance to 20 (max)

Status Display

When Beat Detection is active, you'll see three indicators at the top:

• Status: "On beat" (green) or "Off beat!" (red)
• Detected BPM: Your actual tempo based on your taps
• Accuracy: Milliseconds off from the metronome beat

Tempo Control

Click the large BPM number to open a menu with a tempo slider and quick preset buttons for common musical tempos:

• 60 - Largo, 72 - Adagio, 80 - Andante, 92 - Moderato
• 108 - Allegretto, 120 - Allegro, 132 - Vivace, 144 - Presto

Sound Options

• Beep: Classic metronome tone
• Bass Drum: Low, punchy drum sound
• Cymbal: Bright, shimmering cymbal
• Tock: Wooden percussion sound
• 4-Count Riff: 3 bass hits + cymbal pattern
• 8-Count Riff: Full drum groove (bum bum chish de-de bum bum chish)
• Vibrate: Device vibration instead of sound
• Silent: Visual-only practice mode

Additional Features

• 12 Themes: Choose from various color schemes including light/dark modes
• Screen Wake Lock: Screen stays on during practice (no interruptions!)
• Precise Timing: Uses Web Audio API for accurate, drift-free timing

Technical Excellence

Built using cutting-edge web technologies, our metronome leverages the Web Audio API for high-precision audio generation and the DeviceMotion API for advanced motion detection. The interface uses CSS animations for smooth visual feedback, and the entire application is responsive, working seamlessly across all screen sizes and devices.

Why We Built This

As musicians ourselves, we were frustrated by the abundance of metronome apps filled with intrusive advertisements that disrupted practice sessions. We wanted a simple, reliable tool that just works - no registration, no tracking, no interruptions. So we built one and made it free for everyone.

This metronome is part of AdFreeApps.com, a collection of simple, useful web tools created without the clutter and tracking found on most free online tools. We believe utility apps should serve users, not advertisers.
