Crowd ology is part of Cint surveys who have an app called Opinion app. You can sign up to several Cint survey panels, then download the app and it will show you all the available surveys in one place. I haveCurious Cat on your phone as well.
Crowdology can have high paying surveys. Mintvine And ipsos I say both pay for screenouts.
Panel base pays roughly £6 an hour. Panel opinion can have high paying surveys on as well
