I have a lot of old Moto G androids. The little buggers are real workhorses! I run Perk TV Live! on some and Perk TV on others and one runs the Viggle app. Once I get my repaired S8+ back from Samsung (that's a story for another day), I'll go back to running Live! on my old S5. I have a couple of older iPads that have been sitting idle for the past couple of months but when I used them, they did Pop Quiz. I don't set my phones to do automatic updates. When one comes out for any of the apps, I check the reddit boards to see if anyone is reporting an issue. If no one is, then I will update just one phone to see if I experience any problems before I update the others.
And sometimes I run Perk .TV videos on an old laptop but I find the website to be buggy and I have more success just running EarnHoney on laptops.
If you go to Perk .com, they have daily tasks that earn anywhere from 50-100 points if you complete them. Easy to do and most of them are done via the apps (Perk Scratch & Win, Viggle, Perk TV Live! and Perk TV) and one slideshow. If I find that an app is not earning for me, I switch out to one of the other Perk apps for a while but they tend to be more interactive. I prefer the passive earners.
