SPIN Motion vs Grubby

SPIN Motion is a Physical AI application powered by SPIN OS that enables organizations to track, orchestrate, and automate the movement, care, repair, and service lifecycle of products and assets across the physical world. Using SPIN P1 and P2 dual-frequency smart tags (NFC + UHF), barcodes, QR codes, SPIN Beacons, AI Agents, and intelligent workflows, SPIN Motion creates a real-time intelligence layer over physical operations, allowing businesses to know what assets exist, where they are, who is responsible for them, and what should happen next. SPIN Motion works directly on mobile devices and can also be paired with handheld UHF readers for high-volume scanning, including up to 80,000 scans and movements in a single operation, with the ability to identify and track products inside closed boxes, cartons, containers, pallets, and storage areas without opening them. Designed for factories, warehouses, logistics centres, showrooms, retail stores, museums, archives, event venues, care and repair centres, and recycling facilities, SPIN Motion transforms physical products into connected, intelligent assets.
