Have you ever left home and suddenly wondered: Did I lock the door? Did I close the windows? Is the stove off? Did I bring my keys, wallet, or documents? Leave Check is a simple checklist app for the moments before you leave. It helps you confirm important things once, save a timestamp, and reduce the urge to go back and check again. Built for everyday routines: Leaving home: door, windows, stove, lights, appliances, keys, wallet, phone Before travel: documents, charger, luggage, fridge, trash, doors, windows, outlets Bedtime check: doors, windows, stove, alarm, phone charging, tomorrow’s essentials Leaving the office: computer, monitor, files, AC, lights, access card Leaving a hotel: documents, charger, bathroom, drawers, closet, room card What you can do: Start quickly with built-in checklist templates Tap each item to confirm it clearly Save completed checks with time records Review your recent check history Set local reminders for routines you use often Create custom templates for your own habits Add and adjust checklist items as your routine changes Why it helps: Most of the time, the problem is not that you forgot to check. The problem is that later, you are not sure whether you checked. Leave Check turns that moment into a clear action: open a checklist, confirm each item, and keep a record you can look back on. Privacy and Pro: Your checklists and history are stored locally on your device by default. No account is required. Some advanced features can be unlocked with a one-time Lifetime Pro purchase, not a subscription. Basic checking remains available for free. Check once before you leave. Look back less after you go.
