As many as you wish - the sky is your limit!
Please bear in mind that on some days/months, there will be more available studies, and on others there may be less.
We can't promise you studies every day. Also, try not to compare yourself to your friends or family, as they may have different demographic profiles to you, and therefore may see different studies on their account.
If you are not eligible for currently available studies, then please be patient as new studies are posted regularly. If you've not received any studies in two months, then please feel free to drop our support team a message.
