Simpler Tasker _ help me find it

Hi. I used an app few month ago, it was an automation app, but much much simpler. It worked with adding triggers and setting what to do when that trigger action happens. For example you can set "opening camera app" as a trigger, as a joke I simply set an action to lock the screen whenever someone opened the camera app. It was very simple. I set few triggers and after few weeks I forgot that I even had the app. Last week I had to reset my phone. Nite I can't find it.
Please, help me find it
