VoxPopMe is a great little app that you can download on your smartphone. Pretty much every day they ask for 30 second video responses on a variety of topics, for which they pay 25p. It’s amazing how such a small amount quickly adds up. You get paid within days to your Paypal account. Sometimes they have higher paying activities, these often pay around 65p and sometimes more! They also occasionally send out email surveys with video response sections which pay £1-3.
My top tip is to make sure that you follow that guidelines for response contained underneath the question. Following them, I have never had a response declined and usually earn around £10 per month.
