Pulsar is the metronome you feel. Instead of a click you hear, Pulsar gives a crisp haptic pulse you feel: perfect for practicing in silence, internalizing tempo through your body, and keeping a group in time without a sound. • Silent and precise: practice at night, in an apartment, or backstage. • Apple Watch: the wrist is where haptics are sharpest. The Watch app works on its own, without your iPhone, and keeps going with your wrist down. • The silent conductor: create a session, share it with a QR code, and everyone nearby feels the exact same beat, no sound. • Meters from 2/4 to 12/8, with strong, medium, normal or muted beats, and subdivisions with automatic thinning at fast tempos. • Practice tools: muted bars, step-by-step speed trainer and count-in. • Feel it, hear it, or see it: haptic, click, or on-screen flash (great for deaf and hard-of-hearing musicians). • Presets, setlists for your gigs, and Siri shortcuts. • Tap tempo, VoiceOver and larger text support.
