Protection on software concepts

I developed an app a year or so ago and the app was really quickly ripped off. Totally fine- I learned a lot and gained skills to run my next project more efficiently. My question is- do any of you have any tips for protecting software and applications from being ripped off? I know software is nearly pointless to patent- but I’m curious if there are other methods.

This would also be a web based application, mobile application, and a SAAS.
