Most "did I lock the door" fixes are either expensive smart locks or reminder apps that nag you without confirming anything. Home Secured is a fast, no-account checklist - door, stove, windows, iron - you tap through as you leave. It timestamps your confirmation: "Home secured at 8:14 AM," giving you a real answer later, not a guess. Standouts: zero setup, timestamped confirmation, widget access, custom items (Pro), and a genuinely complete free tier.
