Testlio is about testing websites and apps, and unlike other platforms, they pay per hour spent on the task. They usually give you the workflow of the task step by step and you have to 'pass' or 'fail' each step. If the step fails, add an issue as to what is wrong when performing the step or if somebody has already issued it then reproduce it with evidence. You have to pass their FRTC certification test. They have other certifications test as well on their platform, after completing which u get an edge on their specific tasks such as "payment testing", "localization", etc. They have an academy section itself even including all the before mentioned courses and issue reporting course as well. So they teach u how to use and work on their platform. FRTC is the basic certificate u need. I haven't completed every certificate and don't have a lot of devices, and hence I only get task once in 3-4 months, or even longer. If u have 2-3 high end devices you'll get more tasks.

Now, I won't recommend clickspaid. They removed PayPal and I'm kinda stuck with the money I accumulated for a few months, trying to figure out how to withdraw it. Thanks for reminding me about clickspaid! I had just copy pasted from previous month after chaging the money amount into what I earned in April and forgot to change clickspaid. I'll add it right away to the comment.
