Anyone use rewards hero?

I just saw this app while browsing for a new earner and searching here did no good, figured I'd give it a shot. Haven't earned anything yet. You get a daily login bonus, and can cash out via PayPal and amazon 300 pts = $1. It appears to be mostly an offer wall type earner. Any thoughts? Referral program says it's 20% commission for life.

It says my Ref link is this, but it's also the same as the link to Google play which makes me a little leery: http://ift.tt/1OpYiSH Like I'm just helping someone else or something
