David's Dual Time Keeper

**David's Dual Time Keeper: The Philosophy of Perfect Balance**

Meet David—time-keeping virtuoso, interval maestro, and firm believer that life's greatest rhythms come in pairs.

David discovered something profound: everything worth doing alternates between two states. Focus and rest. Intensity and ease. Push and breathe. The universe doesn't operate on single, monotonous intervals—it pulses, it alternates, it breathes.

Whether you're working in focused sprints, training with intervals, practicing meditation, or studying efficiently—David keeps the rhythm so you can stay present.

**How it works**

Set Interval A. Set Interval B. Choose your cycles. Press start.

The timer oscillates between them—cleanly, predictably, beautifully. Distinct tones and haptic patterns signal each transition. The interface stays out of your way.

**Need flexibility?**
• Save your favorite setups as named profiles for instant reuse
• Add a start delay to settle in before beginning
• Adjust alert volume to your preference

David believes the metronome shouldn't just tick—it should dance between two states, honoring both effort and recovery, both yin and yang.

Simple. Elegant. Balanced.
