● TEN MODULES · ONE DATA MODEL

The complete lean loop — audit, solve, improve, remember.

Most plants stitch together a 5S app, an Excel defect tracker, a paper kaizen box, and a whiteboard for problem-solving. LeanOS unifies them — every module shares the same audit log, RBAC, photos, and leaderboard.

● MODULE 01

Audits

Walk a zone with your phone. AI categorizes each defect across 7 TPM types in 1.2s. Score breakdown shows your path to 5/5.

● PRODUCT TOUR · 4 STOPS

See what your team actually uses every shift.

Operators capture defects on their phone in 30 seconds. Plant managers run A3s, track verified savings, and watch the wins feed fill up shift after shift.

Pulse, today's items, and the modules you tap, not search.

The editorial home screen — italic-accent headline of what matters now, pulse cards for each module, today's actionable items, and a 4×2 module grid. Operators tap. They never search.

Six-step stepper, 6M Fishbone, multi-thread 5-Whys.

Canonical Toyota A3: Background → Fishbone (divergent) → 5-Whys (drilling into a chosen branch) → Countermeasures → Verify → Standardize. AI helps but the team owns the case.

Three columns. Suggested → in motion → verified.

Suggested → in motion → verified. Every closed kaizen carries an annualized savings figure your CFO will trust. No more whiteboard kaizens that quietly die.

04WEB · FEED

Before / after photo cards by end of every shift.

Every closed defect and verified kaizen lands in the wins feed as a before/after photo card. Filter by zone, severity, or person. Built for shift-end celebration and weekly stand-ups.

● WHY IT WORKS

Built for the failures of paper lean.

Most lean programs collapse for the same reasons: audits become one-off projects, no one knows what “good” looks like, and findings rot in a spreadsheet.

● PAPER / EXCEL
What you have today
Quarterly audits, not weekly
Findings rot in PDFs no one opens
Repeat defects untracked
No proof a fix actually happened
Kaizens die in a paper box
A3s scribbled on a whiteboard
No way to coach a new auditor
Multi-plant means 30 separate Excel files
Score is a number with no path to improve it
● LEANOS
What you'll have on day 7
30-second defect capture on the phone

Repeat detection auto-flags habit issues

● FAQ

The questions our buyers always ask.

30 days, no card required. Full product on one site. We help you set up your first plant and run the first round of audits with your supervisors.

Available today as a Progressive Web App (installs in two taps from Chrome on Android) plus a sideload APK every release for plants with locked-down or air-gapped devices. Google Play Store release is on the roadmap for Q3 2026. iOS via Expo Go is functional today; a certified iOS App Store build follows the Play Store ship.

Plant Log is the digital checklist + complaint-forensics module. Operators run versioned checklists from the phone (numeric tolerances, signatures, photos); out-of-tolerance readings auto-create a defect on the board. A separate search timeline lets you type a batch number or part name and instantly see every audit, run, defect, improvement, and A3 that touched it. Audit-grade from day one — append-only signatures, immutable audit log, RLS isolation.

Yes — that's the whole point of the Quality module. SHA-256 hash-chained audit log so any after-the-fact tampering breaks the chain (and we show you a green 'chain intact' badge). Calibration register where every gauge has a cal-cert link + cal-due date, and the run flow refuses submissions taken with an out-of-cal instrument. Dual-signature flow for critical inspections (performed-by + verified-by). Shift / batch cohort lock so closed records become immutable except via super-admin escalation. Templates can require a batch / lot reference for traceability. Everything an IATF 16949, ISO 9001, GMP, HACCP, or AS9100 auditor reads first — captured by design, not bolted on later.

Yes. The mobile app captures audits and defect actions to a local queue when offline. As soon as the phone hits Wi-Fi or cellular, the queue drains automatically — including photos.

You own all your data — defects, photos, kaizens, A3 cases, audit logs. Your workspace is fully isolated from every other customer's at the database level. India-only data residency available on enterprise plans; EU residency on request.

It returns 0–3 suggestions per photo — never auto-creates defects. The auditor confirms or ignores each one. For fix plans, 5-Whys, and Fishbone, the AI is grounded in your plant's past data, not generic templates. Every AI suggestion is advisory; a human decides before any action.

Yes. Multi-site hierarchy with site/plant scoping is built in. Owner sees the org, Admin sees the org, Member sees their assigned zones, Auditor is read-only.

We follow canonical Toyota A3: Background → Fishbone (divergent) → 5-Whys (drilling into a chosen branch) → Countermeasures → Verify → Standardize. AI helps with 5-Whys conversation and Fishbone bucketization, but the team owns the case.

After the pilot: setup fee + per-seat/month annual prepay, with PPP-adjusted regional pricing. Operator seats are inexpensive; manager seats with reporting are higher. Contact us for a quote.
