I have used this app but it is not useful. We download this app for earning money by referring but it does not add our referral under us. I have been referred almost 20-25 people. But I got only 3 referral . My friend was also using this long ago he got once paid but after that he didn’t received any payment from ChampCash. He only Referred me. He was having 80-90 refferal.So don’t waste your time search a good paid app. This is fraud
