Your body.
Your experiment.
N1 app analyzes your health data to find patterns and lets you test what actually works - for you.
You’ve tried the supplements. The routines. The ‘life hacks.’
Some helped. Most didn’t.
And you never knew why.
Because your body isn’t average.
What if you could finally know what works?
N1 learns what's normal for you.
Your resting heart rate has been 4 bpm above your baseline for 5 days.
Personal baselines, not population averages.
Real patterns, not arbitrary thresholds.
Changes detected when they matter - to you.
Stop guessing. Run an experiment.
