Run a trial on yourself.

Turn a hunch into a proper experiment. N1 Trial is a mobile app for N-of-1 trials: design one in about a minute with an AI collaborator, follow the plan for a few weeks while your smartwatch, Oura or Whoop, or a daily check-in that takes a few seconds, does the measuring, and find out what actually works for you. When the data can’t tell yet, it says so.

Built on an established research method

N-of-1 trials are a recognised way to study how a change affects one person. Read the AHRQ guide to N-of-1 trials. N1 Trial is for everyday habits. It isn’t a medical device and doesn’t give medical advice. The app is in development and is being tested by a small group of invited testers.
