Most metronomes only keep a tempo. This one accelerates gradually while you play, and remembers every minute you practice. Accelerating Metronome is a practice instrument, made by a working musician in Seattle over forty years of daily practice. This is not what a product committee would have asked for. It is a cross between a Stairmaster and Duolingo. Designed to motivate you to keep going and growing in your practice. ACCELERATOR Choose a beginning tempo, a target, and how long you want to practice. It climbs the Ramp in steps, so you invest your time playing rather than reaching for the Dial. When it reaches the target it keeps going at that tempo, and extra time is counted separately as Play Time. Practice and playing are not the same thing. And are not counted as if they were. Save and name your own Custom Ramps. PEAK SPEED Mark the tempo where you hit a wall so you have a visual record of your limits. We graph your Peak Speed(s) so you can see your progress. SPIN THE METRONOME Press this and let the Universe choose a tempo for you. Practicing only at the tempos you like is how blind spots appear. And this is the cure. Spin the Metronome before a Group Rehearsal to bring everyone into listening and warming up together beginning with a cue from the Muse. PRACTICE HISTORY: YOUR PRACTICE, VISUALIZED OVER TIME Every session is documented: when, how long, which tempos, and what you were working on. Name your own Categories and each one has its own color. The Calendar shows a month at a glance, with Celebrations and Gold after you have completed a full hour of practice. STREAKS + CELEBRATIONS A Streak counts the days in a row you practiced. Momentum may motivate you to pick up the instrument on an evening you had decided not to. And practice more than an hour every day from Sunday to Saturday and the whole week is celebrated in Gold. A ROCK SOLID METRONOME Tempo is set from a rotary dial you drag with your thumb, the way a hardware tempo wheel works. Three default voices with ten alt Sound Banks deliver a wide variety of sounds. Select a Time Signature, and the downbeat gets its own sound. An integrated Tuner and Tuning references from 432 to 445. TAP TEMPO + TYPE TEMPO Tap the BPM Window, and the tempo changes to what you tap. Press and hold to type in a tempo. MIXING The click plays over (or under) your other app's sound, music, podcasts, or a backing track without interruption. The Metronome keeps going when you switch apps or the screen locks. Beats align with the audio hardware's clock rather than a timer, so nothing drifts while you are not looking. Optional Haptics let you feel the Beat, the screen stays awake while it plays, and a Loudness Booster doubles the click volume. UNIQUE PRACTICE TOOLS Beat Map is a grid where you choose 1, 2 or 3 sounds per beat, and save your Maps by name. Group Loops captures and layers what you play, cut at the bar lines, as WAVs. Beat Oscilloscope lets you see where you play relative to the click. Beat Speedometer tells you the tempo you are actually keeping, worked out from the gaps between your sounds. Or press SPIN, let the Universe name a tempo, and find it from memory with nothing to hear. FLEXIBLE SETTINGS Display Size with three choices, for easier reading. High and Low Pass filters shape the click. YOURS, PRIVATE No account, no login, no shared analytics, no advertising, no tracking, no subscription. You buy it once. Your Practice History is only on your phone. Only two features send data, and both are OFF unless you turn them on: 1. Leaderboard, where you choose the name that appears, and 2. Find Quotes online, which sends a musician or artist name you type to Wikiquote. You can back up your practice history to your own Files or iCloud Drive whenever you like, in a plain file you can read, and import it onto a new device. It works offline. Portrait or landscape. In English, Spanish, Italian. An accelerating practice tool, to grow and visualize your work over time.
