Andon Tool is a browser-based digital andon system for small and mid-size manufacturers. It replaces radios, whiteboards, and scattered spreadsheets with one place where the floor's needs are visible, owned, and timed. Operators request help from any phone, tablet, or shared floor kiosk. Requests appear on a live board, are claimed by name, and response and completion times are recorded automatically, counting working time, not breaks. Every plan includes floor requests, production scheduling, daily KPI boards, and downtime tracking. No hardware to install, no ERP project, and most plants set up in days. Built by a continuous improvement coordinator in Sioux Center, Iowa. Plants within about 50 miles get on-site setup. Free tools: andontool.com/free-tools See it running: andontool.com/demo
