SLG Metronome

A metronome with exactly what drum practice needs — nothing more.

■ Rock-solid timing
Clicks are scheduled ahead of time against the audio clock, so the beat stays steady even if the screen stutters. 20-500 BPM.

■ Per-beat accents
Tap a circle to cycle through accent, normal and mute. Build odd meters freely — anything from 1 to 12 beats.

■ 10 rhythm patterns
Quarter, 8th, triplet, 16th and sextuplet, plus swing (shuffle), dotted 8th + 16th, 16th combinations and offbeat (rest + 8th).

■ Tempo trainer
Set something like "every 4 bars, +5 BPM up to 160" and it steps the tempo up for you — ideal for building speed from a slow start.

■ Quick BPM
Save the tempos you use often as one-tap buttons. Reorder them by dragging, long-press to edit.

■ Presets
Store BPM, beats, accents, subdivision and trainer settings per song. Flip to the next song with the ◀ ▶ bar at the top, and any change you make while practising is saved back to that preset automatically.

■ Practice log
Every start-to-stop stretch is logged with its length and BPM, grouped by day with daily totals — see at a glance how much you actually practised.

■ Visual sync adjustment
If the flash and the click drift apart on Bluetooth headphones, line them up yourself with a slider.

■ Stays out of the way
Keeps the screen awake while playing, keeps playing when you switch apps, and shows no ads.

■ Cloud save (optional)
Sign in with Google to save the items you choose — presets, quick BPMs, settings, practice log — to the cloud and load them on another device. Nothing syncs automatically; data is sent only when you tap Save. Everything works without signing in, and no personal data is collected until you do.
