About BodyClock
BodyClock is an app for people who want to live closer to their body clock. It does three things: it shows you where you are in your day right now, it helps you set your clock with light and timing, and it gives each part of your day a short plan, so you know what to do when you get there.
Why it exists
It started as a timer. Every morning, the person who built BodyClock started a stopwatch on waking, to know how many hours they had been up and roughly which part of the day they were in. That habit turned out to be more useful than any to-do list, and BodyClock grew from it: a wave of eight phases drawn from your wake time, a few lines of routine for each, and the daily signals that keep the clock in place.
It is built with people in mind whose clocks run late, including many people with ADHD, who benefit most from a day that carries its own structure.
How we read research
The articles in our field guide are written by BodyClock Editorial and follow the same three steps:
- Evidence. We start from what studies actually observed, and link to the primary source, usually on PubMed.
- Interpretation. We say how strong the evidence is. An observational association, a small pilot and a controlled trial are different things, and we name which one we are relying on.
- Experiment. Every article ends with a small test you can run on yourself, because your own pattern should overrule the average.
When research changes or we find a mistake, we correct the article and update its date. Tell us if you spot one.
What the app measures, and what it does not
BodyClock works from the times you give it: your wake time, the wakes and bedtimes you log, and the routine lines you write. From those it draws your day, estimates when your body wakes on its own, and measures your social jet lag. These are estimates from self-reported times, useful for seeing direction and change.
They are not a clinical measurement. Properly measuring circadian phase takes controlled conditions and markers like melatonin onset in a sleep lab, and no app replaces that.
Not medical advice
BodyClock is educational. It never diagnoses, and nothing in the app or the field guide replaces a clinician. If you have a sleep disorder, ADHD, or any health concern, please see one.
