## What is Jazz Time Trainer?

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.
