I usually start my mornings by tallying up my earnings the previous day per app. Pencil and paper because I'm retro and excel is usually inconvenient.
I have two spare phones, an HTC Incredible and an LG Ally (I don't recommend this one at all for farming) and I have both of them running the swag apps, except for IndyMusic because that's a waste of time. The HTC gets done first, so once that's done I throw on Checkpoints(non-ref, ref code: gingeronastick) and play the videos there to get around 100 points.
While all those apps are running I'm doing Swagbuck dailys, (dailies?) JunGroup, encrave, nGage and SBTV, that earns me if I have nothing else to do that day, around 150-300 points there. Then I do the SuperLuckyButton on Superpoints, but the results are so minimal I barely count them. After that I spam searches on BingRewards for my daily points there.
On my primary phone, I have Perk Screen installed, so from that I earn 30-120 Perk points a day, sometimes more if I run PerkTV while idle, but I usually don't. When I'm not doing anything else (IE: on the toilet, at a stoplight, etc) I spam mobile searches on BingRewards for the points there. I also have several coupon/receipt apps on that phone so when I do some shopping I can scan the receipts and get rebates, and that usually earns me a couple bucks a week.
So overall, on a good day, I'm earning around $5/day by using around 12 apps. Not nearly as crazy as some when it comes to Perk farming, if I did I could easily double or even triple my daily earnings, but the point of entry on five+ android phones is a bit unjustifiable at the moment.
