Oglas is based under the concept of earn per call.
Its gives 0.1 rs per. Some times it does’t add the balance. Once the balace reach to 30 rs it can be redeemed. But I tried too many times to redeem it and my efforts was in vain. I was fed up. The offer are very low which gifted for apps for downloading. Too many advertisements makes your mobile slow. Sometimes unable to take calls by this app. It show some reason everytime when I made a attempt of redemption.
