BeatNTempo Live

BeatNTempo - Per-Measure Custom Metronome

Everything regular metronomes can't do, in one app.

[ Core features ]
- Per-measure / section BPM, time signature, accents, swing (tempo changes mid-song? No problem)
- Multi-device ensemble sync - play together over Bluetooth (BLE) or the same Wi-Fi, clock-synced
- Jazz 2 & 4 backbeat preset + free swing ratio control
- Per-beat accents: strong, normal, weak, silent
- Per-beat subdivisions: quarter, eighth, triplet, sixteenth
- Polygon beat visualizer + full-song progress bar with measure markers

[ 7 genre presets ]
- Jazz backbeat (2 & 4) - for walking-bass and solo practice
- Jazz swing (full) - swung eighth-note ride pattern
- Rock / Pop - strong 1 + backbeat
- Waltz (3/4)
- Bossa nova
- 6/8 ballad
- 4/4 straight

One tap applies the preset (time sig, accents, swing all updated).
After applying, fine-tune any single measure or section.

[ Perfect for ]
- Jazz musicians who need a real 2 & 4 backbeat
- Ensemble / combo players matching the actual tempo flow of pieces
- Anyone working in unusual time signatures (waltz, 6/8, mixed meters)
- Musicians frustrated by "single BPM per song" metronomes
- Bass, drums, guitar, piano, and any other instrument

[ How it works ]
1. New song - set title, BPM, time sig, accents, swing, measure count
2. Or pick a genre preset, then fine-tune
3. Split into sections to set tempo/meter per part
4. Play - visualizer and clicks show the beat flow

[ Ensemble ]
- One device hosts a room with a PIN; others join with the same PIN
- After clock sync, everyone starts together on the countdown
- Pause / resume / start-from-measure supported

[ Also ]
- Dark mode
- Auto-save
- Loop mode, auto-follow current measure during playback
- Works offline (no internet required)
