What it is

Lean Day Toolkit is an offline tool for warehouse and factory supervisors. Open it on the floor, capture what you find in under a minute, and leave with a record and a list of actions that each have an owner and a date. There is no server and nothing to sync — every audit, photograph and report stays on the device until you choose to share a file yourself.

First time in? One tap loads six weeks of realistic sample data — 27 audits across five areas, 40 waste logs, a full month of the SPQDC board, boards, studies and a line map — so you see a working system, not an empty app. Wipe it when you are ready for your own.

The tools

New in this version

  • Floor notes Free — a notepad one tap away in the top bar, on every screen.
  • Floor timers — in the top bar, with a countdown visible wherever you are.
  • More of it in your language — the default 5S checklist, the 5 checklist template packs and the posters the app prints now follow the app language.

Tools marked Free stay free for good. Everything else is open during the free trial and in the full version — see what it costs.

On the phone

Captured on an iPhone; the app looks the same on Android and on tablets, where the main screens open two panes side by side.

The learning section — free forever

A built-in lean library that never locks, whether or not you ever buy anything:

Seventy-seven pieces in all — 31 films, 26 lessons and 20 tool videos — plus the glossary and quiz. The films and lessons are in all eight languages. Four are narrated in your own language; German, Polish, Romanian and Turkish are subtitled. The tool videos are narrated in English.

The app is in English, Spanish, Portuguese, German, Italian, Polish, Romanian and Turkish. The default 5S checklist follows the app language until you edit its questions, the 5 checklist template packs come in every one of the eight, and the 19 posters print in the language the app is set to. The diagram editor is in English.

Printing posters and the checklist template packs are part of the full version. The English posters are also free to download from this site — see below.

Free posters — the same 19 the app prints

One A4 teaching poster per tool, drawn in the app's own design system: what it is for, the four moves, and the one line to remember. Free to download, print and pin up in your own workplace — all 19 as PDF.

What it costs

Free to start, one payment for everything. Every tool is open for your first 30 minutes, and you can extend that free for 7 days, once. After that, 5S audits and their PDF, the action list, the stopwatch, near-miss reports, 5 Whys, takt and OEE, floor notes and the whole learning section stay free. The full version opens every other tool with a single purchase — no subscription, no seats, no renewal.
