Door Alert If Left

First, thanks to anyone who can help me.

I had to replace an open/close sensor with a SmartThings Multi Sensor. On the old sensor I had a smart app called Door Alert if Left … where by I could choose the state of the sensor (open or closed), for how long it was in the state and it would send me a notification to both my cell and to the mobile app on my families phones.

I can’t find the smart app anywhere in the list of available apps. Can anyone direct me to where this app is located?

Thanks

There is a SmartApp called “Left It Open” in the IDE under the Templates.

EDIT: If using just the app, there is one called “Something Left Open” in the Energy Management category.
