Jazz Time Trainer is a focused metronome and inner-pulse trainer built for jazz musicians, drummers, students, and serious practice sessions. This is not a generic click app. JTT is designed around the way musicians actually train time: internal pulse, click independence, 2 & 4 practice, gap-click work, odd meters, grouping, swing ride practice, subdivisions, and clean visual feedback. Key features: - 20-400 BPM tempo range - Stable high-output click engine - All Beats, 2 & 4, 1 Only, 4 Only - Gap Click and Random Drop timing challenges - Common time signatures for jazz practice - Odd meter and grouping concepts for modern jazz training - Subdivision practice for 8ths, 16ths, and triplet feels - Customizable beat accents and mute states - Multiple click sound profiles, including voice count mode - Swing Ride practice with Center, Ahead, and Layback feel options - Memory slots for saving practice setups - Minimal dark interface designed for practice, not distraction - Media mix mode for practicing while playing along with other audio JTT is made for musicians who care about time feel, not just BPM. No ads.
