BPM Forge

BPM Forge is the tempo tool for the minutes between soundcheck and doors. Tap along to a song (or type the number) and the BPM appears with a steadiness reading. From that tempo you can start a metronome with a count-in, save the song to a setlist, read off delay times for the FX rack, and — one tab over — tune up on a chromatic tuner. Free, and built for a phone in a dark room.

Who it is for

• Drummers and bands who keep a setlist of tempos so the top of every song is right, every night.
• Musical directors who count the band in at the right tempo.
• FOH engineers who want delay times in milliseconds for the song's real tempo, dotted and triplet values included.
• Guitarists and string players who need a tuner without an app-store detour.

What makes it different

• Four tools that share one tempo. The delay table reads the tapped tempo; the setlist starts the metronome; nothing else joins them up.
• A setlist of tempos with name, BPM, time signature and a note, per song, with a lock for the show and JSON export.
• Any time signature. Six presets plus a custom numerator and denominator — 6/8 really clicks twice as fast as 6/4.
• A real tuner. Chromatic plus presets for guitar, bass, ukulele, violin, viola, cello, mandolin, banjo and drums; custom tunings; strobe view.
• Follows your account. Setlists and preferences open on your other devices when you are signed in.
