simple loop machine vs Centronome

simple loop machine is a straightforward loop-style music app: record up to eight samples from the microphone, assign them to pads, then play, loop, reverse, trim, and scratch. No DAW-style complexity—great for ideas, practice, and live sketches. Features • 8-pad recording - Free mode: hold an empty pad to record; release to stop - Fixed mode: set BPM and bars, tap an empty pad to record a fixed length • Play/stop, loop, reverse playback • Waveform view with trim handles • Zoom (full waveform / selection range) • Volume and pitch per pad • Scratch strip (drag left and right) • Mix recording: capture pad playback into one mix; play, export, or delete • Settings: default record mode, default BPM/bars for fixed mode, delete all pads • In-app languages: Japanese, English, Simplified Chinese, Traditional Chinese, Korean Privacy & data • Samples and mixes are stored only on your device • No account required • Microphone is used only for recording to pads • Export uses the system share sheet (Files, AirDrop, etc.) Notes • Use caution with headphones or speakers—levels can be loud • Microphone permission is required on first launch • A real device is recommended for recording (simulator has no mic) Support: contact us via the Support URL on the store listing.

Centronome puts a high-precision tuner and a rock-solid metronome on one screen. Tune while you keep time — no tab switching. TUNER, BUILT LIKE AN INSTRUMENT YIN pitch detection with FFT harmonic verification, based on current pitch-tracking research, for stable readings without octave errors Resolution well below one cent on steady tones; Precision mode reads to two decimal places Strobe display: the slightest drift shows as rotation — when the wheel stops, you're in tune Four accuracy modes: Easy (±5 c), Normal (±3 c), Precision (±1 c), and Strobe 9 instrument presets: Chromatic, Guitar Standard, Drop D, Guitar High-Precision, Bass, Ukulele, Violin, Voice, and Piano single-note Per-string targets: see which string you're closest to and how many cents remain Piano mode estimates string inharmonicity (B coefficient) and the deviation of the second partial A4 reference adjustable from 410 to 480 Hz in 0.1 Hz steps, sharp/flat notation, and a calibration offset for known hardware bias Microphone input uses iOS measurement mode — no AGC or noise suppression coloring your signal A METRONOME THAT DOESN'T DRIFT Click timing is decided on the audio clock, immune to dropped frames and notifications — measured jitter is on the order of microseconds 20–300 BPM with tap tempo Time signatures: 1/4–5/4, 6/8, 7/8, 9/8, 12/8 Subdivisions: quarters, eighths, triplets, sixteenths — with swing (50–75%) on even subdivisions Fully editable accent pattern per beat; accents differ in timbre, not just volume Four click sounds (Classic, Woodblock, Digital, Soft) and optional haptics The pendulum and beat flash are derived from the actual audio output time, so what you see matches what you hear USE BOTH AT ONCE Tuner and metronome run side by side. When the click plays through the speaker, Centronome knows exactly when it happens and automatically discounts those moments in the pitch confidence. Headphones make simultaneous use even more stable. NOTHING TO HIDE An on-screen diagnostics view shows the sample rate, I/O buffer, analysis window, and real-time processing load. ADS & PURCHASES Centronome is free to use. A single one-time purchase removes ads permanently — there are no subscriptions. PRIVACY Microphone audio is analyzed on-device in real time only.
