You already experiment on yourself — matcha for focus, magnesium for sleep, screens off at nine. Elyxis gives those experiments a method: one variable, a fair schedule, and a verdict worth acting on.
Placebo, a bad night's sleep, stress, the weather — they all hide whether a habit truly worked. Humans are terrible at separating signal from coincidence. That's not a willpower problem. It's a math problem.
"I slept better on tea nights" — or did you just only have tea on relaxed Sundays? Passive trackers can't tell the difference.
Manual spreadsheets, exports, and DIY math collapse the moment life gets busy. The experiment dies by day four.
People spend $50–100 a month on supplements and gear with zero evidence any of it works for them.
No streaks. No guilt. A five-second check-in, and the science runs quietly underneath.
Pick a template — "Cold Shower vs. Warm Shower for Energy" — or build your own. Elyxis shuffles your schedule so the result can't fool you.
One nudge a day, one slider. Sleep, steps and screen time sync on their own — nothing to type, nothing to journal.
When the protocol ends — 14, 30 or 45+ days, fitted to the intervention — Elyxis separates the effect from the noise and writes the verdict. If the data can't tell, the verdict says exactly that.
A statistical model separates the habit's effect from your sleep, stress, and screen time — so you see its impact, not the day's mood.
You get the size of the change and how sure we are — a credible interval, never false precision.
Every protocol is designed for you — shuffled A/B blocks, washout days for slow-clearing substances, a length that fits the intervention. Rigor you don't have to think about.
Matcha improved your focus by +1.8 points — but mostly on days you slept under 6 hours. On well-rested days, it made no real difference.
effect +1.8 · 88% likely real · sleep-dependentNo waiting in the dark until the last day. Elyxis shows the leaning as it forms — 'likely helping, ~65%' — with its uncertainty, sharpening with every log. And when the data can't tell yet, it says exactly that.
