New in 2.2: spoken counts in 7 voices and 14 languages, the String tuner, setlists and camera scanning, your own recordings in Play, and Apple Watch on its own. One app for every musician: a precise tuner, a metronome that counts out loud, piano accompaniment to play along with, and your sheet music, with the tools floating right on the score. Play in sync with anyone, on any phone, tablet or watch. In 15 languages. PLAY ALONG - Practice with piano accompaniment for voice, violin and more, from public-domain scores - Three playing styles: Steady, Practice and Expressive - Slow it down to 75 or 90%, or push to 110% - Loop any bars by dragging the edges of the piece, then repeat with a rest in between - Tempo ladder: each repeat steps the tempo up until you reach 100% - Slow a hard passage down inside the loop, with an easy step back up to tempo - Metronome click on or off, count-in, piano volume - Save your setups as presets; they follow your account to every device - New pieces arrive in the app as they are added - Bring your own: practise with your recordings (MP3, M4A, WAV), MIDI or MusicXML files TUNE - Accurate from the lowest bass string to the top of the piano, shown to 0.1 cent - Strings in pure fifths, the way string players tune by ear - Tune against a drone with fifth and octave, in three sounds - Violin, viola, cello, double bass, guitar, bass, ukulele, mandolin, banjo, harp, piano, voice, and transposing winds and brass - Alternate tunings and capo, automatic string detection, or lock a string - Concert A from 410 to 480 Hz - Temperaments: equal, just, Pythagorean, meantone, Werckmeister III, Vallotti and Kirnberger III - Five views: the new String, Halo, Arc, Line or Strobe, plus a pitch trace of the last 8 seconds - Display as Bb, Eb or F for transposing instruments, an in-tune zone and a gentle haptic tick KEEP TIME - Subdivisions, an accented downbeat and meters from 2 to 12 - Tap tempo and a big, clear beat you can see - Counts & Kits: seven voices — men, women and a kid — count out loud right on the beat, "1. 2. 3. 4.", in 14 languages, with "and" on off-beats and 5-6-7-8 count-ins for dance class - The ORB: a floating metronome on top of your score that pulses with every beat - Bluetooth delay calibration so the click lands on time in wireless headphones - Sync rooms: everyone in the room hears the same beat, on iPhone, iPad, Apple Watch and the web together. Hosting a room is free. Patent pending. READ - Your PDF library with Recent, Starred, setlists, tags and search - Scan paper music with the camera, cleaned up for sheet music; edit, reorder and rotate pages - A 30-day Trash, and share scores with or without your markings - Free public-domain scores from IMSLP - Annotate with Apple Pencil, a stylus or your finger: pen, highlighter and string stamps, in layers - Tap the edge of the page to turn, or use a Bluetooth page-turner pedal - Your scores sync to your Metro X account and open on all your devices - Bring your library over from another sheet music app APPLE WATCH - A standalone watch app: metronome with taps and clicks, the String tuner, Play and Sync rooms, even without your iPhone nearby ONE ACCOUNT Sign in with Apple, Google or an email code. The same account works on iPhone, iPad and metrox.app. Metro X is free to start.

This app has quickly become one of the best tools for practicing and enjoying music. The built-in metronome is accurate and easy to use, which makes it perfect for keeping time whether you’re a beginner or advanced player. Beyond that, the app comes packed with other thoughtful features that make practice sessions smoother, more efficient, and more fun.The design is clean and intuitive, so it doesn’t take long to find what you need. Whether you’re rehearsing alone, playing with a group, or just wanting to improve your timing, this app provides all the essentials in one place. It’s clear a lot of care went into building it, and it shows! I highly recommend it for anyone who wants a reliable, all-in-one music practice tool.

An Amazing App!

If you’re a musician, student, or just someone trying to sharpen your sense of rhythm, Metro X is a solid companion. The app combines a clean, customizable metronome with a library of useful music tools, making practice sessions more productive and less frustrating.The metronome offers flexible tempo ranges, time signatures, and even subdivision options, which are super handy for practicing tricky rhythms. The ability to change the sound (from clicks to digital beeps or woodblock tones) keeps it from becoming boring over long sessions.Beyond the basics, the app includes extras like a tuner and a simple practice tracker, which helps you stay consistent and see progress over time. The interface is intuitive, so even beginners can get started quickly without confusion.As a musician myself, I have tried this and it is so amazing! It has countless features that you can use while practicing and the app itself is so fun to use. I think that it is a must have tool if you are a musician.
