SLEEP COACHING
Better sleep starts with
the rest of your day.
PULS3 reads your sleep and recovery from Apple Health, connects it to your stress, training and daily habits, and adjusts your evening plan to match — so you don't have to work out what tonight should look like.

Most sleep apps stop at a score. PULS3 starts there: what changed, why it might have, and how tonight's plan should shift.
It reads your sleep stages, timing, HRV and resting heart rate from Apple Health, and looks at them alongside the rest of your week — because a rough night is often about the day that came before it.
What you get
A short daily read on your sleep and recovery, with your evening plan adjusted to it. Plain language, tied to your own data, not generic sleep tips.
As you keep going, the coaching adapts to your patterns, your training load, your stress and your stage of life.
Grounded in real tools
PULS3 tracks how your sleep changes over time using the Insomnia Severity Index (ISI), a validated questionnaire — asked in conversation, not handed to you as a form. If your answers point to moderate or severe insomnia, it tells you plainly and recommends seeing a professional.
When it makes sense, the coach walks you through the core techniques from cognitive behavioural therapy for insomnia (CBT-I): rebuilding a steady sleep rhythm, strengthening the link between bed and rest, quieting a racing mind, and shaping a sleep-friendly environment. Caffeine timing and light-exposure guidance are evidence-based.
It knows its limits
A coach isn't a doctor. PULS3 doesn't diagnose sleep disorders. If something looks like it needs a clinician, it says so and helps you get ready for that conversation.
Part of the whole picture
Sleep doesn't happen in isolation, and neither does your coaching. The same PULS3 that reads your nights also sees your movement, nutrition and stress, so the advice fits your actual life. It reads sleep through Apple Health, including Apple Watch and other devices that sync there.
Private by design
Privacy-first: your health data, conversation history and memory live on your device. When you sign in, they sync between your own devices end-to-end encrypted — our servers only ever hold data they can't read. When the coach needs a language model to reply, your message is sent through a pseudonymous proxy, used to answer, and not kept by us; no human reviews it. Read our privacy policy.
