I was skeptical about email-based coaching, but the weekly plans are so specific to my life. I'm falling asleep 20 minutes faster and waking up actually refreshed.

No app to check, no ring to charge, no data overload. Just clear instructions in my inbox every Monday. It's the simplest wellness thing I've ever done.

The 30-day audit was eye-opening. I didn't realize how much my evening routine was sabotaging my sleep. Three weeks in and my energy levels are transformed.

Not at all. Cirql works entirely without hardware. We build your plan from a quick intake questionnaire about your habits, schedule, and environment. If you happen to use a tracker like Apple Watch, Fitbit, or Oura, you can optionally share that data for even more personalized recommendations — but it's never required.
Sleep trackers tell you what happened last night. Cirql tells you what to do about it. We don't just give you data — we give you a clear, week-by-week action plan based on sleep science. Think of it as having a sleep specialist in your inbox, without the specialist price tag.
Every Monday, you'll get an email with your personalized weekly sleep plan. It includes specific bedtime and wake time recommendations, evening wind-down routines, environment adjustments, and lifestyle tweaks — all tailored to your unique situation and updated based on your progress.
Most people notice improvements within the first 1-2 weeks — falling asleep faster, waking up less, feeling more rested. Meaningful, lasting changes to sleep quality typically happen within 3-4 weeks as the AI learns your patterns and refines your plan.
Yes, absolutely. The monthly coaching plan has no minimum commitment. Cancel with one click whenever you want. The Sleep Audit is a one-time purchase, so there's nothing to cancel — the 30-day plan is yours to keep forever.

No hardware to buy. No app to download. Just science-backed guidance, delivered to your inbox, designed for your life.
