UnderSink Planner

UnderSink Planner is a mobile app that lets homeowners take a photo of their under-sink cabinet, then drag and drop fixtures like disposals, traps, and dishwasher lines to plan the optimal layout. It provides step-by-step assembly instructions and alerts users to code violations, eliminating guesswork and multiple trips to the hardware store.
