What's inside

Far more than a metronome.

Most apps do one thing. Metro Gnome gives you a precision metronome, a smart chromatic tuner, a tuning drone, a chord finder, a rhythm game, a speed trainer with Groove Check timing feedback, a practice timer, and Gnotes that unlock items for Metro - all free, all in one place.

Precision Metronome

Hardware-anchored timing that doesn't drift. Built on raw AudioTrack for sample-accurate beats.

  • Tap tempo - just tap the beat
  • BPM presets - save your favourite tempos
  • Custom accent beat and time signature
  • Multiple sounds: click, hi-hat, woodblock, warm, bell
  • Background play

Smart Chromatic Tuner

Tunes in noisy rooms by profiling your environment first, then locking on to your instrument.

  • Ambient noise detection - ignores room sound
  • Speech rejection - filters voices
  • LOCKED / ACQUIRING state display
  • Reference pitch 415 to 466 Hz, shared with the drone
  • Loopback and tuning fork calibration

Tuning Drone

Hold a reference note and play against it by ear. The beating slows and stops as you lock in, which is intonation practice in one sound.

  • Any note from C2 to B5 on a drawn keyboard
  • Follows the tuner's reference pitch
  • Root and octave blends, Pure and Warm voices, all free
  • Reed, String, and a pure-fifth blend as one-time extras
  • Keeps sounding while the metronome runs
  • Also free in your browser: online tuning drone

Chord Finder

Play a chord one note at a time, or tap it on a fretboard or keyboard, and get its name, spelled and explained.

  • Names any chord you play or tap
  • Guitar fretboard and piano keyboard
  • The bass note decides: C6 or Am7, slash chords included
  • Alternative readings and a line about each chord
  • Hear it back, arpeggio then together
  • Also free in your browser: online chord finder

Rhythm Game

Guitar-Hero-style note lanes. Tap the screen or clap - the mic detects your rhythm in real time.

  • 5 difficulty levels
  • Tap or clap to play
  • PERFECT / GOOD / ALMOST scoring
  • High scores per difficulty
  • Acoustic Echo Cancellation - play while the metronome runs

Speed Trainer

Nail a passage slowly, then let the tempo climb on its own until you can play it up to speed.

  • Automatic BPM ramps
  • Set start, target, and step size
  • Choose how many bars per step
  • Ascending or descending tempo
  • Built for clean, gradual speed gains

Groove Check

Switch the mic on during Practice or the Speed Trainer and the app listens to you play, then tells you how closely you landed on the beat.

  • Tells your playing from the click by its sound, not its loudness
  • One quick device check corrects for audio latency
  • A timing score for every session
  • Timing Bonus Gnotes for staying in the pocket
  • Runs on your device; nothing is recorded or uploaded
  • Try the free rhythm test in your browser

Practice Timer & Streaks

Set a focused session and build a daily streak that keeps you coming back to the instrument.

  • Timed practice sessions
  • Daily streak and best-streak tracking
  • Weekly practice calendar
  • Total sessions counter
  • Great for building a habit

Gnotes & Collectibles

Earn Gnotes as you practise and unlock accessories and scenery for Metro the Gnome.

  • Earn Gnotes from every activity
  • Loyalty milestones
  • Unlock Metro's accessories and forest world
  • Ad-free session for hitting your daily goal
  • A reason to come back tomorrow

Who it's for

Made for every musician, not just pros.

Whether you're nailing a groove, staying in tune, or teaching the next generation - Metro Gnome fits the way you actually practise.

Guitarists

Tune between songs with a tuner that works on a loud stage. Name any chord shape you find on the neck. Lock in a BPM preset for each song in your set.

Drummers

Drill subdivisions with multiple click sounds. Use the rhythm game to test your pocket before the gig.

Music Teachers

Assign practice sessions with the built-in timer. Put a drone on for intonation work. Students build streaks and you see the habit forming.

Students

Free forever. No subscription to forget about. The rhythm game makes a chore feel like a challenge.

The mascot

There's a gnome behind the metronome.

Metro isn't just a logo. He's got a backstory, an item collection you unlock by practising, and a surprising amount of engineering behind that pendulum swing.

Questions

Frequently asked questions

Is Metro Gnome really a free metronome app for Android?
Yes - completely free. The metronome, chromatic tuner, tuning drone, chord finder, rhythm game, and speed trainer are all free with no time limits. There are optional purchases to remove ads or unlock cosmetic items, but the core tools never cost anything. Metro Gnome works on Android 7.0 and above, fully offline.
How does the BPM counter and tap tempo work?
Just tap the TAP button in rhythm - Metro Gnome calculates your BPM from the interval between taps (requires at least 2 taps within 2.5 seconds). You can also save any BPM as a named preset and switch between songs instantly. The metronome uses raw AudioTrack on the Android audio stack for sample-accurate timing that doesn't drift over long sessions.
Does Metro Gnome have a speed trainer?
Yes. The speed trainer ramps the tempo up automatically. Set a start BPM, a target BPM, a step size, and how many bars to play at each step, then practise a passage slowly and let the app raise the tempo for you until you can play it up to speed. It's the simplest way to build clean speed on any instrument.
Does the tuner work in a noisy practice room?
That's exactly what it was designed for. When you open the tuner, it spends a few seconds profiling your room's background noise. After that it distinguishes your instrument from the noise floor, rejects voices and broadband sounds, and only locks on to a stable musical tone. You'll see on-screen guidance (QUIET → ACQUIRING → LOCKED) so you always know what it's hearing. It works fine in rehearsal rooms, kitchens, or wherever you practise.
What makes this better than Metronome Beats or Pro Metronome?
Metro Gnome is the only free app that combines a precision metronome and a chromatic tuner that works in noisy rooms. Metronome Beats has no tuner at all. Pro Metronome switched paying customers to a subscription without warning. Metro Gnome has no subscription, no bait-and-switch, and a built-in rhythm game on top.
Does Metro Gnome have a tuning drone?
Yes. The Tuner tab has a built-in tuning drone: a sustained reference note you tune to and play against by ear, so you hear the beating slow and stop as you lock in. Pick any note from C2 to B5 on a drawn keyboard and add the octave above. It follows the tuner's reference pitch, so setting A4 to 442 Hz moves the drone too. The Pure and Warm voices and the root and octave blends are free; Reed and String voices and a pure-fifth blend are optional one-time extras. The drone keeps sounding when you switch to the metronome, so you can practise time and intonation together. Try the browser version, or read how to practise intonation with a drone.
Does Metro Gnome have a chord finder?
Yes. The Chords tab names any chord one note at a time. Play the chord as an arpeggio into the microphone, or tap the notes on a drawn guitar fretboard or piano keyboard, and the app names it (C, Am7, D7/F#), spells every note, offers alternative readings, and can play the chord back. The lowest note counts as the bass, so C E G A reads as C6 with C at the bottom and Am7 with A at the bottom. It is free and works fully offline. There is also a browser version you can use right now.
Is Metro Gnome good for music teachers?
Yes. The built-in practice timer lets you set a session goal (5, 10, 15, 20, or 30 minutes). When the session completes, the app tracks a daily streak and total sessions - so students build a practice habit and you can check in on their consistency. Recommend it to students as a free app they can use immediately, on any Android phone.
Does it work offline?
Fully. The metronome, tuner, tuning drone, chord finder, rhythm game, and speed trainer all run entirely on-device - no internet connection required. The only feature that needs a connection is loading ads (which you can remove with a one-time purchase).
What Android version do I need?
Metro Gnome requires Android 7.0 (API level 24) or higher. It targets Android 13+ for the best experience but runs well on older devices too.
