Calibrate: a free plan for your daily timing

Calibrate starts from your actual schedule, including when you wake, work and wind down, and suggests one change to start with so you are not trying to fix everything at once. It is free.

Open calibrate.day on your phone. You answer questions about your normal day, such as when you wake, when you get outside, when you have caffeine, when you eat, how your evenings go and when you go to bed.

Calibrate then lays out your day as a set of timed steps, from waking up to putting your phone away for the night, and shows you which step to start with. A step can be as specific as getting outside between 6:45 and 7:45 AM.

You get a written version of your day with a time attached to each step and one step marked as the place to begin. Starting with one change makes it easier to tell what is helping before you add the next.

It is built for people who feel tired in the morning and wired at night, whose weekends throw off their week, or who want their energy to line up better with work and family.

Calibrate is wellness education. It works from your answers and does not measure your body clock, diagnose a sleep disorder or replace medical care. If you have long-running insomnia, loud snoring, pauses in breathing at night or heavy daytime sleepiness, talk to a clinician.

Calibrate is a separate service with its own terms and privacy policy. Using it does not make you Dr. Bakri's patient.
