This is not a scam, we don't work for this website, we just like it.
Basically you download a free "sponsored app" and open it for at least 30 seconds. After doing so, you get 75 points. After you rack up a few hundred points you are able to download one of a selection of apps (top names). I have tried this and it works and is legit.
This totally sounds like a sell / scam but it's not haha.
