## What is Did I Lock It? Lock'd?

"Did I really lock the door?"

If that thought pops up on the way out, at the office, or already in bed, Lock'd gives you a clear record to check. It turns "did I?" into "checked."

For Those Last-Minute Doubts
If you want one place to confirm the front door, stove, windows, and switches, a timestamped checklist helps.

Your Before-You-Leave Checklist
Door lock. Gas valve. Windows. Stove. Outlets. Add anything you want to check. Tap once to confirm — and keep a record that you're all set for today.

Group Your Routines
Create separate lists for Leaving Home, Before Bed, and Morning Routine — so the right items show up at the right moment, and nothing extra gets in the way.

Proof You Can Check Later
Every confirmation is timestamped. If you wonder later, open the app and see exactly when you checked.

Fresh Every Morning
Your list resets automatically each morning, so yesterday's checks never blur into today's list.

A Gentle Daily Reminder
Pick a time that fits your day, and Lock'd nudges you to run through your list — so confirming the door, the gas, and the windows becomes second nature. Already checked everything today? No reminder. Lock'd never nags.

Beyond Door Locks
Wallet, phone, keys, charger — and more. Set up lists for daily medication, household chores, work routines, and habits you want to keep. Lock'd works for every "did I do it?" — not just "did I lock it?"

No Account. No Cloud Sync.
No account. No cloud sync. Your checklist data stays on your device, and the core checking flow works offline.

Designed for Clear Checks
A quiet dark theme, large tap targets, and a layout that makes it clear when you're done for the day.

Download Lock'd and keep your before-you-leave checks in one place.
