CastleWise is the owner's manual your house never came with. Every home runs on information nobody writes down: the furnace filter size, the paint code in the hallway, when the water heater went in, which weekend the gutters are due. CastleWise keeps all of it. KEEP THE RECORDS Twelve categories covering appliances, HVAC, plumbing, paint, flooring, safety, exterior, service history, and tests like radon and water quality. Quick-pick chips so you never face a blank form. Snap the data plate and it saves. Every record links to a room, and the app builds a map of your home as you go. FILE THE PAPERWORK A document vault for manuals, warranties, receipts, insurance policies, inspection reports, permits, and contractor quotes. Attach a manual to the appliance it belongs to. Everything searchable, everything on your phone. GET THE REMINDERS Seasonal checklists for spring, summer, fall, and winter, fully editable with real notifications. Plus home dates for filter changes, HVAC service, smoke detector batteries, gutter cleaning, septic pumping, insurance renewals, and holiday lights. FOLLOW THE GUIDES 86 full step-by-step project guides, each calling out the classic mistake first-timers make. Eleven calculators that turn a project into an exact shopping list. A know-how library and a 100-term trade dictionary in plain words. AND WHEN SOMETHING BREAKS Describe the problem in your own words, add a photo if it helps. You get the likely causes ranked most-common-first, numbered fix steps, the parts that usually solve it, and an honest call on whether it is safe to do yourself or time to call a licensed pro. 267 verified error codes across 53 appliance brands, and 120 problem playbooks, all working offline. MAP YOUR ELECTRICAL PANEL Label every breaker in a grid that looks like your panel door. CastleWise knows your panel brand and tells you the exact breaker to buy, because Square D QO and Homeline are not interchangeable no matter what the box says. CAPTURE A PAINT COLOR Photograph the wall, tap the spot, keep the exact color forever. PRIVACY No account. No login. Your records, photos, and documents stay on your phone. Optional deeper analysis sends only that one question and photo, stores nothing, and can be switched off.
