I also helped build this app (in ClojureScript). Having spent several years of my life as a nomad, I don’t like keeping paper manuals of stuff I buy. I think having a single place to keep all that info, + automatic links to replacement parts or fixit-guides, is a useful thing and much better than typing arcane model numbers into manufacturers websites every time you need to look up a manual or part.
I have used this app for over a year and I've added all of my power tools and appliances. Any time I need to figure out how to change an obscure battery, replace the wire in my weeder, and of course, order a new water filter for my fridge, I've finally gotten in the habit of saying, LOOK IN CENTRIQ. Its all there.
Centriq is like a medical record for your home. It notifies you when your stuff needs maintenance or if the manufacturer recalls it. When something breaks you can get DIY repair instructions or a professional at the push of a button. If your home is damaged or you're selling it you can report not just the 4 walls but everything inside. I like that in particular because it disincentives short term thinking–using cheap parts to build and sell a house that looks good on the outside but crumbles inside.
