Stop searching, start finding. ObjectRelay gives your home a visual memory: take a photo of a shelf, a drawer or a whole room, and AI lists every item it sees. Where did you put the spare keys? Who borrowed your drill? Do you already own that tool you are about to buy again? ObjectRelay answers in seconds. AI SCANNING • Point your camera at any space and capture everything in one shot. • AI names each item, picks a category and notes its visible condition. • Expiry dates printed on items are read automatically. • Estimated second-hand value, in your local currency, helps you decide what to keep, sell or donate. ORGANIZE BY SPACES Create spaces that match your real home: the garage shelf, the kitchen drawer, the bedroom wardrobe, a storage box. Move items between spaces and see where each one has been. FIND ANYTHING INSTANTLY Type what you are looking for, even as a question like "Where are my keys?", and ObjectRelay shows the item and the space it is in. LENDING TRACKER Record who borrowed what and when it should come back. Overdue items are highlighted so nothing is forgotten. EXPIRY & REMINDERS Track best-before dates for food, medicine and anything with a shelf life, and get a reminder before it is too late.

Verdict
The clearest difference is in-app purchases: MQTTAnalyzer at none against ObjectRelay AI's 2. MQTTAnalyzer also leads on update cadence (every 5 days vs every 2 months). ObjectRelay AI's advantage is iOS requirement (15.0 vs 18.0). On price, ads and device support there is nothing between them.
