Custos vs Preppr

What do you do when power, internet, and cell service all fail at once? Custos is your offline companion built for exactly that moment. An app that needs no internet — because it has to work when nothing else does. Unlike any other emergency app: 100% offline, no cloud, no servers, no dependencies. WHY CUSTOS? In a blackout, flood, or earthquake, you don't just lose comfort — you lose access to every piece of information you rely on. Where's the nearest hospital? How do I treat a burn? How do I purify water? How do I survive 72 hours without power? Custos has the answers. Already installed, already there.
