Pro Metronome — A Precision Metronome and Tuner for Practice, Rehearsal, and Stage

Pro Metronome combines a sample-accurate click engine, real-time chromatic tuner, structured training tools, setlist playback, practice timers, and external MIDI control in one focused app for musicians.

A native Core Audio-based C++ engine calculates beats on the audio render thread, not UI timers.

— Precision Metronome —
• Sample-accurate timing with no timer drift
• BPM control with ±1 adjustments, press-and-hold control, and TAP tempo
• Built-in patterns for triplets, sixteenths, syncopation, dotted figures, and rests
• Create custom subdivision patterns with per-step sounds and accents
• Per-beat accent control: strong, medium, or normal
• Multiple click sounds, including human voice counting
• Adjustable metronome volume and Left / Center / Right channel output

— Practice Timer —
• Independent countdown and count-up timers in a movable floating window
• Sync timers with metronome playback or control them manually
• 0.5×–3× timer sizes, with text and icons rendered at the selected size
• Choose from multiple completion sounds, including a short bell
• Reset countdown and count-up independently from the screen, MIDI, or a mapped foot pedal

— MIDI and Foot Pedal Control —
Control the app without touching the screen:
• Bluetooth MIDI support for compatible pedals, controllers, and interfaces
• Bonjour network MIDI for hosts on the same local network
• MIDI channel filtering: all channels or CH 1–16
• Learnable mappings for play/stop, start, stop, tap tempo, tempo changes, previous/next song, and timer reset commands
• Context-aware tempo control on the main metronome and in setlists

— Training and Setlists —
• Training mode for structured tempo work and repeatable practice routines
• Setlists save each song’s tempo, meter, rhythm pattern, accents, sound, and bar count
• Switch between Normal cards and a one-line Compact list
• Keep the beat panel visible while scrolling through songs
• Automatically bring the active song into view when navigating with a Bluetooth keyboard or MIDI
• Hands-free previous/next song control for rehearsal and live performance

— Built-in Tuner —
The chromatic tuner uses YIN pitch detection for fast, stable pitch tracking across guitar, bass, piano, strings, brass, woodwinds, and voice.
• Create custom instruments with 1–12 strings
• Select notes from A0 to B7 for extended-range instruments
• Play reference tones for preset and custom instruments
• Pro users can adjust the global reference pitch from 415 to 466 Hz

— Practice, Personalization, and Sync —
• Practice-time and app-open-time statistics with charts and selectable date ranges
• Custom themes plus Dark, Light, and System appearance
• iCloud sync for settings, presets, timers, custom subdivisions, training plans, setlists, custom instruments, and practice statistics
• Premium diamond indicators automatically disappear when Pro access becomes active
