Money saving apps?

So my accounts are set up really weird where I can’t transfer money into my savings account without going to the bank and having a big process. That being said, I’d like to limit myself on how much I spend to help save money. The issue here is that I can’t be trusted to do so cause I am admittedly irresponsible. Does anyone know any good FREE apps that can help you save money/limit your spendings? 

(I have an iPhone by the way)
