Time-poor, health = wealth.
We're building the performance OS for people who don't have hours to spend on their health — but refuse to let it slide. One number, the real reason behind it, and the next move.
Make peak performance cost less time, not more.
For serious people, health is the asset that compounds everything else — yet it's the first thing that gets squeezed when the calendar fills up. The quantified-self world answered that with more dashboards, more charts, more numbers to interpret. We think that's backwards.
LockIn90 collapses your wearables, your logs and your day into one explainable energy score and the single decision that follows from it. No interpretation tax. The signal, the cause, the move — before noon.
We're clinical about the science and athletic about the intensity. That tension is the whole product.
“Time is the real constraint. A number you can't act on is noise. Your body, not a population average.”
Calibrated to your physiology over 30 days
Time is the real constraint
Athletes and operators don't lack data — they lack minutes. We design for the 20-second check, not the hour-long deep dive.
A number you can't act on is noise
Every score carries its attribution. Late caffeine −9, morning lift +6 — so the fix is obvious, not inferred.
Your body, not a population average
The model calibrates to your physiology over 30 days. Your baselines, your thresholds — not someone else's.
It started with a 3pm crash nobody could explain.
Three chapters in the short version. The full one lives on the About page.
- 2024 · THE ITCH
Too much data, no decision
I was drowning in rings, scores and readiness numbers from four devices that never agreed — a lifter who tracked everything and still couldn't tell what to do about a flat afternoon.
- 2025 · THE MODEL
Effect-generators & the curve
I built a pharmacokinetic-style engine that attributes each shift in energy to a real cause, then projects a 34-point daily curve. The first time it nailed a 3pm dip three days early, I knew.
- 2026 · THE COMPANY
One number, shipped
LockIn90 launched on web, iOS and Android with Oura, WHOOP, Apple Health, Garmin and CGM integrations — still designed, built and run end-to-end by one person.
Four principles we actually ship by.
Not poster words. These show up in code review, in roadmap calls and in what we refuse to build.
01 · Precision
Clinical-grade rigor over vibes. We report p-values, model versions and confidence — and we'd rather say "not yet calibrated" than fake certainty.
02 · Explainability
We show our work. No black-box score ever ships without its attribution. If we can't tell you why, we don't tell you the number.
03 · Privacy-first
Your health data is yours. Genetic and cycle data is AES-256-GCM encrypted, coaches see only what you grant, cohorts are k-anonymized — and we never sell data.
04 · Athlete-obsessed
Built with powerlifters, endurance athletes and performance pros in the loop. If it doesn't survive contact with a real training week, it doesn't ship.
A one-person company, on purpose.
No org chart, no committees. One person designs it, builds it, ships it and answers your email.
I'm the whole company. I design the product, write every line of the backend, web and mobile apps, run the models that compute your energy score, and keep the lights on in production.
That tight loop is the point: no hand-offs between "the designer" and "the engineer," no roadmap-by-committee. If something's wrong, there's exactly one person to fix it — and I will.
“I built LockIn90 because I was the time-poor person it's for. I wanted one honest number and the real reason behind it — so I made it, and kept it small enough to stay honest.”
"The first recovery app that tells you why — not just how you slept."
