Champ cash is a very disgusting app according to me, you can download to from google play store very easily but before installing on your phone, you have to complete challenges first. If we talk about its challenges, that is also very bad, money wasting & totally time wasting. For that you have to install at least 8 apps like Flikk, amazon, Jabong, myntra etc.
First of all Champ cash is a refer & earn App which is a very tedious & old concept. In the concept of this app you have to refer your referral id to your friends through any media, same thing have to do your friends and so on. So you to make a chain, which is a very difficult task. I could not earn 1 rs. from this app. It is completely useless app according to me. I neither like this app nor its features.
I will never recommend you for such a type of apps.
