About this app

Did I lock the front door? Did I lock the car?

Did I Lock It? gives you a fast, certain answer. Mark anything locked or unlocked in one tap and the app remembers, with a timestamp, so you never have to turn around and check.

TRACK ANYTHING
• Doors, cars, gates, sheds, lockers, luggage — add as many as you like
• Group them into categories like Home, Car and Office
• Star the ones you check most
• Full history for every item, so you can see exactly when it changed

SIX WAYS TO BE REMINDED
• Scheduled — pick a date and a time
• Location — get nudged when you leave home or work, using a radius or a safe zone you draw yourself
• Car Bluetooth Assist — the moment your car disconnects, the app asks if you locked it. Completely hands-free.
• Bluetooth beacons — proximity reminders from a small BLE tag
• NFC and QR door tags — stick a tag by the door and tap it on the way out
• On app open — a nudge the next time you pick up your phone

HOME SCREEN WIDGETS
Seven widgets, so you can check and change things without opening the app:
• Security Overview — is everything locked, plus one-tap Lock All
• Favorites and Category lists — tap any row to flip it
• Lock Control — a single item, tap to lock or unlock
• Quick Actions, Next Reminder and Streak

MORE THAN LOCKS
• Rich notes with photos, drawings, voice memos and checklists
• Parking spot photos for your car
• Google Assistant shortcuts
• Backup and restore

BUILD THE HABIT
Confirm your locks daily to build a streak, earn trophies at milestones, and spend a grace day when life gets busy.

MAKE IT YOURS
• Light, dark, system and vibrant themes with your own accent colour
• Adjustable text size and colour-blind friendly palettes
• Optional fingerprint or PIN lock on the app itself

PRIVACY
Everything stays on your device. Location is only used when you switch on a location reminder, and it never leaves your phone.

Stop turning the car around. Get Did I Lock It?
Never wonder if you locked up. Track locks and cars with smart reminders.
