The Tools
Not sure where to start? You don't need any lean experience to use these tools. Our getting started guide walks you through the basics — what lean improvement is, why it works, and how to run your first improvement session.

Load an app on your phone or tablet
Every tool runs in your browser — no app store needed. For the best experience, install it on your home screen so it works like a native app, including offline.
How your data is stored
Your data is stored locally in your browser using localStorage. It stays on your device — never sent to a server, never uploaded to the cloud, never shared.
Back up and export your data
Every app has a JSON export button. It creates a file you can save, share, or reload later. Make exporting a habit — it's your backup and your way to share work with colleagues.
Working offline
All Gemba Suite tools work without an internet connection once loaded for the first time. Poor hospital WiFi is never a barrier to data collection at the gemba.

Built for the Gemba — where the real work is done.
Every tool in the Gemba Suite is a single HTML file that runs entirely in your browser. No accounts, no cloud storage, no IT department required. Your data stays on your device until you choose to export it.
The tools are designed for mobile-first use at the lab bench, the ward, or the clinic — wherever the work happens — the gemba. They work offline, so poor hospital WiFi is never a barrier to improvement.
Gemba Suite is a process improvement toolkit, not a clinical system. It does not connect to hospital systems, does not process patient data, and does not require regulatory approval. It is the digital equivalent of the whiteboards, sticky notes, and Excel spreadsheets that improvement teams already use — just faster, more structured, and available on any device.
