Did I Lock It? helps users avoid unnecessary anxiety after leaving home.

Many people experience doubt moments after stepping out—wondering if
the door was locked, the gas was turned off, or appliances were switched
off. This app provides a simple confirmation system before you leave.

Users mark a quick checklist, which is time-stamped automatically.
Optional photo proof can be added for extra reassurance. Later, instead
of worrying, users can simply check the confirmation.

The app does not connect to smart devices and does not monitor your home.
Everything is manual, private, and stored locally.
