Run a complete experiment

Every intervention runs the same honest loop. The whole product on one screen.

01 Hypothesize

Tell Ren what's off. It reads your data and writes a real experiment: a named intervention, a numeric target, a fixed verdict date.

Deep sleep's been rough. I'm up at 3am most nights and dragging by afternoon.

Your Oura has deep sleep averaging 62 min over the last 2 weeks, low for you. Nothing before bed right now, and no magnesium in your labs. Want to run one as a proper experiment?
PROPOSED EXPERIMENT
Magnesium glycinate, 400 mg
…will raise 14-day average deep sleep from 62 to at least 90 min.
Goal: Deep sleep 14-day avg ≥ 90 min

See what’s working, and what’s worth a look.

Every marker from every device and lab lands in one place against its optimal range, so the things worth improving surface on their own. Each one becomes an experiment you can actually run.

  • Every marker against its optimal range: see at a glance what’s dialed in and what isn’t.
  • Anything off becomes a hypothesis you can test, not just a number you noted.
  • Ren keeps watching in real time — as your numbers fluctuate, it flags what needs work and suggests the next experiment to run.

Stop guessing what works.

Most supplements and habits are a shot in the dark — you never really know if they did anything. Ren fixes a target and a deadline before you start, then measures the result, so you get an honest picture of what's actually working in your body.
