It’s important to understand that earnings are not constant. If we have a lot of traffic for your country, you will see more earnings, and if there is less, you will see fewer earnings. Some days you may not see any earnings – that’s normal.
Don’t forget that EarnApp only works if you have a residential IP address. You may experience low (or in some cases, zero) traffic if you are using a VPN or a virtual machine.
In any case, note that bandwidth used for payment calculations is measured on the EarnApp server side. What you see on the client side is an approximate number only.
