Every experiment below comes pre-loaded in the app with synthetic data showing real results. Read the science, see the confidence sequences, then launch your own N-of-1 trial.
The Vaporfly revolution changed marathon racing forever. A 4% running economy improvement is one of the most replicated findings in sports science. But does it hold for your stride?
Read more →Caffeine has a 5-hour half-life, but genetic variation means yours could be 3 or 10. This experiment produced the largest detectable effect of any sleep intervention we tested.
Read more →Cold water immersion has exploded in popularity with 334% search growth. The parasympathetic activation is real — but is 2 minutes enough to move your heart rate variability?
Read more →The most studied ergogenic aid in sports science meets Apple Watch running metrics. A meta-analysis of 21 studies shows 2–5% endurance improvement — can you detect it in your own pace data?
Read more →Alcohol's effect on sleep is surprisingly complex: it increases deep sleep but devastates REM. Five metrics tracked over 120 days reveal a nuanced picture most sleep trackers miss.
Read more →Huberman's #1 sleep supplement recommendation has plausible biochemistry and growing trial evidence. Instead of trusting a population average, run the experiment on yourself.
