MetroGnome vs Pro Metronome

MetroGnome is an iPhone and iPad app combining a metronome, rhythm-pattern editor, and instrument tuner. Its metronome runs from 20 to 300 BPM and offers tap tempo, customizable meters, subdivisions, nine synthesized tick sounds, and live beat accents ranging from strong to silent. Eleven flamenco palos include traditional accent cycles that can be edited during playback. The pattern editor supports unlimited measures, mixed time signatures, rests, tuplets, repeats, tempo changes, and real staff notation. The tuner covers 60 instrument tunings across five families, plus chromatic Any Note mode and 16 historical reference pitches such as Baroque A=415 and Verdi's A=432. These tools run on-device and offline without an account or login, while clicks continue with the screen locked or another app open. The maker says tuner audio is analyzed in memory and not recorded, stored, or transmitted. iOS 17 or later is required; Android is coming soon.

Pro Metronome is an Android and iOS app for music practice and stage performance. It offers 13 metronome tones, adjustable time signatures and accents, and tempo entry by tapping. The maker says its Real-Time Playback technology provides accuracy of ±20μs. A basic tuner is included; Pro adds a tuner with customizable A4 calibration and temperaments. Pro features also include subdivisions, polyrhythms, programmable playlists, a rhythm trainer, and automatic tempo changes in Practice Mode. On iOS, playback can sync between devices via Ableton Link, and Bluetooth or MIDI control pedals are supported. The App Store listing covers iPhone, iPad, Apple TV, and Apple Watch, with iPhone compatibility requiring iOS 16.0 or later. The free version includes basic metronome features and is ad-free. Listed paid options are $0.99 a month, $3.99, paid once for Pro Version, and $3.99 a year. On Android, flash mode requires a flash-enabled device and camera permission, while vibration requires a phone.
