Question 1

What does Calibrate actually give me?

Accepted Answer

A personalized 24-hour day plan with specific timed actions: your morning light window, caffeine cut-off (if relevant), evening dim-down, and lights-out target. All built from your real schedule and constraints.

Question 2

Do I need to buy anything?

Accepted Answer

No. Calibrate starts with behavior and the tools you already have. Product recommendations are optional and only appear when they solve a real constraint you actually have.

Question 3

How long does the setup take?

Accepted Answer

A few minutes. You walk through your actual day (wake time, light access, caffeine, screens, and constraints) and it builds the plan as you go. It feels like a short conversation, not a form.

Question 4

Can I change it later?

Accepted Answer

Yes. Recalibrate whenever your schedule, season, or travel changes. Your plan updates to match your new reality, same process, fresh output.

Question 5

Is this based on real science?

Accepted Answer

Yes. The plan is built on circadian biology, your body's 24-hour timing system, regulated primarily by light and dark. The cue hierarchy (morning light first, evening dimming, consistent wake time) reflects the published evidence.

Question 6

Will it tell me my sleep stages or readiness score?

Accepted Answer

No. Calibrate doesn't track or score your body. It builds a forward-looking plan based on your inputs, not a retrospective reading of biometric data. It tells you what to do, not what happened.

Question 7

What if I can't follow the plan perfectly?

Accepted Answer

That's expected. Every action has a bad-day minimum version. The goal is the best routine you can repeat most days, not a perfect one you abandon after a week.

Question 8

What's the 28-day ramp?

Accepted Answer

Week 1: stabilize with up to 3 actions. Week 2: shift your schedule only if sleep is protected. Weeks 3 and 4: consolidate and add one more lever. The ramp is gentle by design, never an overnight overhaul.

Question 9

Do I need a smartwatch or wearable?

Accepted Answer

No. Calibrate is a plan, not a tracker. It works with nothing but your real schedule, and it never depends on a device reading your body.

Question 10

Why morning light specifically?

Accepted Answer

Light in the first hours after waking is the strongest signal your body clock gets. Specialized cells in your retina read that bright light and set the brain's master clock for the rest of the day, anchoring when energy, focus, and sleepiness arrive.

Question 11

Is evening screen light really a problem?

Accepted Answer

Yes. Bright, blue-rich light at night delays melatonin and pushes sleep later. Studies on evening screen use show a measurable shift in sleep timing. Dimmer, warmer, and earlier reduces the hit, you don't have to go dark.

Question 12

How soon will I notice a difference?

Accepted Answer

Many people feel steadier morning energy within a few days of a consistent wake time plus morning light. Larger shifts in when you naturally get sleepy take roughly one to three weeks of repetition.

Question 13

What if I work night shifts?

Accepted Answer

Honestly, shift work runs against your biology and is the hardest case to fully solve. Calibrate anchors to your actual wake time and protects the light and dark windows around it, which helps, but it can't erase the strain of a rotating schedule.
