Why we built LockIn90.
Serious performers were drowning in wearable data and starving for answers. We built the layer that finally explains why your energy is what it is — clinical-grade, personalized, and never a black box.
It started with a 3pm crash nobody could explain.
Our founder was a competitive powerlifter wearing an Oura ring, a WHOOP strap, and logging macros to the gram. Three devices, a dozen dashboards, and still the same maddening question every afternoon: why is my energy in the floor today?
The data was all there — HRV down to 48 ms, resting heart rate up 6 bpm, sleep short by an hour — but nothing connected the dots into a decision. The apps showed what happened. None of them showed why, and none of them learned him.
So in 2024 we set out to build the missing layer: a single explainable energy score that traces every point up or down to a real cause, calibrates to your own physiology, and tells you what to change before noon. Not another data firehose — a decision.
“"The number was 62. The apps said 'low readiness'. We needed them to say why."”

Clinical-grade, never a black box.
We hold ourselves to the standard of evidence, not vibes. Every score is defensible, personal, and shows its work — three principles we won't compromise.
Evidence, not vibes
Effects come from pharmacokinetic half-life models and effect-generators, validated with paired t-tests and reported p-values — not hand-tuned heuristics. (p < 0.05 to ship a driver)
Calibrated to you
No population averages. The model learns your baselines over ~30 days, so the threshold that flags a bad night is yours — not a generic cohort's. (model v4.2 · n = your events)
Show your work
Every point is attributable: late caffeine −9, short sleep −7, morning lift +6. If we can't explain a shift, we don't surface it. Explainability is the product. (100% attributed scores)
From a 3pm crash to a performance OS.
A short history of building the explainable energy layer — one model, one integration, one principle at a time.

Founded — the explainability bet
One founder, one conviction: wearable data is useless without the why. I sketched the first energy-attribution model on a whiteboard the same week I quit my job to build it.

First energy model (v1) shipped
Our first personalized energy score went live with PK half-life effect curves for caffeine, sleep debt and training load — and from day one it explained every point it moved.

Wearable integrations went live
Oura, WHOOP, Apple Health, Garmin and Android Health Connect connected in a single tap. Sleep, HRV, RHR, strain and readiness started flowing straight into the model.

Calibration that learns you
The model started tuning to each athlete's own baselines over 30 days, and pattern detection began surfacing repeating loops — validated with paired t-tests before we'd ever show them.

Coach mode & end-to-end encryption
Coaches got a privacy-gated roster view of their athletes' readiness, and coach DMs shipped with Signal-protocol end-to-end encryption (PQXDH). Trends are shared; raw private logs never leave the device unencrypted.

2.1M scores & a 31-day forecast
Members in 41 countries, model v4.2, and a forward energy forecast that projects planned training and habits through the same explainable pipeline. Same conviction, much sharper math.

Principles we won't trade away.
01 · Explainable or it ships
If we can't trace a number to a cause, it doesn't reach you. The "why" is non-negotiable.
02 · Health is wealth
Built for the time-poor who treat recovery like a serious investment, because it is one.
03 · Your data is yours
Cohorts are k-anonymized and opt-in, coach views are consent-gated, and we never sell data.
04 · Earn trust with rigor
p-values over promises. We'd rather show one defensible driver than ten flashy guesses.
Built by one person who lived the problem.
No team page, because there's no team. Just the founder — and a refusal to ship a number he can't defend.
I'm the powerlifter who lived the 3pm crash for years before deciding to model my way out of it. Today I design the product, build the backend, web and mobile apps, own the energy model and the PK curves, and run it all in production myself.
LockIn90 is a deliberately one-person company. Keeping the whole stack in one head is what lets me hold the "show your work" rule — no number ships unless I can trace it to a real cause.
“"I built the layer I wished existed: one explainable score, the cause behind it, and the next move — before noon. Small enough to stay honest, and accountable to exactly one person."”
A performance tool — not a medical device.
We're proud of our science, and we're equally clear about its limits. LockIn90 helps you understand and act on your own energy and recovery patterns. It does not diagnose, treat, cure or prevent any disease.
- A performance & recovery insights tool for understanding your own patterns.
- Transparent about uncertainty — confidence and calibration are shown, not hidden.
- Not a diagnostic device, and not a substitute for professional medical advice.
- Never a replacement for your doctor — always consult a clinician for medical concerns.
LockIn90 is intended for general wellness and athletic performance. If you have a health condition or notice concerning symptoms, talk to a qualified healthcare professional. See our Terms and Security pages for the full detail.
