Does Step actually build your credit?

I'm curious to know, does the Step app actually help build credit for its users? I've heard some claims that it can improve credit scores, but I'm hesitant to invest my time and money into it without some solid evidence. Can you provide any insight into how the app works and whether it's truly effective in boosting creditworthiness? Additionally, are there any potential risks or drawbacks that I should be aware of before signing up for Step?
