The "did I lock it?" feeling always hits after you leave. Snap a photo before you go so you can check it from anywhere. Miss one, and we'll let you know.
About five minutes after you leave, it hits you: did I turn off the stove?
StaySure doesn't make that thought go away — it just gives you a fast way to check when it does.
Turn off the stove, take a photo. Lock the door, take another. You won't remember doing it, but the photo will still be there.
Add a Place (Home, Work, wherever) with a short list of what to check before you leave. If you actually leave with something unchecked, you'll get one notification. Check everything, and StaySure stays quiet — that's the whole point.
Photos disappear automatically after 24 hours and are never saved to your camera roll. Your location, your photos, everything you add — none of it leaves this phone. There's no account to make.
Using it comes down to three things: add a place (up to 5), add what to check (stove, door, windows, whatever matters to you), and take a photo before you walk out.
A few things worth knowing:
- Alerts only work if location access is set to "Always." "While Using the App" can't notify you once StaySure is closed.
- "Precise Location" needs to be on too - without it, your location is too rough for the app to notice you've left.
- Because of ordinary GPS drift, the alert usually arrives a bit after you've actually left, not the instant you cross the line.
- Force-quitting the app (swiping it away in the app switcher) blocks alerts until you open it again - that's an iOS limitation, not something we can fix.
- There's a small banner ad on the Settings screen and the Places list. Never on the checklist or camera screens.
No payments, no account, nothing locked behind a paywall.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
StaySure now speaks English and Japanese, not just Korean. Place and task suggestions are tailored to each country's habits instead of just translated — you'll see different default checklists depending on your language. Screenshots and store copy got a refresh too.
