About this app

Still asking “Did I lock it?” halfway down the street?

Did I Lock It? is a fast, privacy-first way to track doors, cars, and “did I…?” items. Toggle Locked/Unlocked with a tap, add real-world context (notes, photos, voice), and use smart reminders that nudge you at the exact moments you usually forget.

Quick lock tracking (built for real life)

Create multiple locks (doors, car, windows, gear, meds—anything)

Organize with categories and favorites

One-tap Locked / Unlocked toggle

Optional history log (so you can review what happened)

Smart reminders that actually work

Choose the kind of reminder that fits your routine:

Location reminders with geofences (circle) or Safe Zone polygons

Car Bluetooth Assist: reminder on car disconnect (optional delay)

Beacon Assist (BLE: iBeacon / Eddystone)

Remind-after-unlocking timers

Scheduled reminders

Launch reminders (next launch / every launch)

Evening nudge, Inside Too Long checks, and bedtime sweep

Door tags (QR + NFC)

Turn your door into a shortcut:

Generate a QR or write an NFC tag that deep-links to a specific lock
(didilockit://door/{id})

Optionally auto-run an action: open status, toggle, mark locked/unlocked, or open notes

Set per-lock and global tag defaults

Notes, photos, and voice—right where you need them

Text notes + checklist notes

Voice memos

Photo notes

Special photo tools: door/key reference shots, and a car parking spot gallery

Widgets + Assistant shortcuts
