Is there an app that can be triggered to do certain things?

I havent had an iPhone since iPhone 4 was out and newly came back to a 6s+. I had an app on my previous android phone that was called Trigger. It could be triggered by almost anything, and it would do most anything that you could make a phone do with a specific trigger. For example.... When i got to work and it picked up my wifi signal there, it would automatically turn my ringers and notifications down to minimum levels. That is one of many things it would do. It could send text messages if certain triggers were set, etc. Here is the link https://play.google.com/store/apps/details?id=com.jwsoft.nfcactionlauncher&hl=en

I have searched online, in the app store and in the forums here. But i cant find anything comparable to do what im needing it to do. Any suggestions to a comparable app?

Thanks in advance
