Sleep coaching built around
your real nights.

Most sleep tools stop at scores. PULS3 starts where those tools end: what changed, why it matters, and what to do next.

It reads sleep architecture, bedtime timing, HRV, and resting heart rate trends so you can make one better decision tonight instead of guessing.

What you get

A quick daily read on your sleep and recovery patterns, plus one focused action for tonight. Coaching is plain language and tied to your actual data, not generic sleep tips.

Recommendations adapt to your context, including training load, stress patterns, and life stage.

Clinically grounded

We track how your sleep is changing over time using science-backed questions, so you can see real progress. If scores suggest moderate or severe insomnia, we recommend professional help — no exceptions.

If sleep needs real help, your coach walks you through proven techniques step by step: rebuilding your sleep rhythm, training your body to associate bed with rest, managing racing thoughts, and creating a sleep-friendly environment. Caffeine cutoffs, light exposure, and sleep environment guidance are all evidence-based.

Built to stay lightweight

No long forms. You can start with your goal, answer sensitive profile questions later, and keep refining over time.

PULS3 currently reads sleep through Apple Health, including Apple Watch and other apps or devices that sync into Apple Health.

Private by default

PULS3 is local-first: your health data and conversation history are stored on-device by default. Some coaching responses use pseudonymous cloud model calls with minimized context. Safety audit records are stored locally by default and excluded from routine cloud sync.
