Earn Honey

Earn Honey is probably my favorite site to use right now in terms of how much money you can make in as little time. In the span of 3 days I earned enough HD (Honey Dollars) to redeem a $25 Amazon gift card. Earn Honey is extremely passive as well, which is always a plus. You must have a computer in order to use the website since you will be playing videos. You receive credit after the viewability meter turns either red or green. Your meter is basically telling Earn Honey that your window is in focus (or it's an active window) and it's able to detect you're playing the video ad. You receive a lot more points when it's able to detect that. I wouldn't have more than 2 windows running side by side since you won't receive many points if it can't detect an active window; not to mention it may slow down your computer by having too many videos playing at once). You are receiving points for the ads that play, and not the actual video content. For some reason Android & iOS phones/tablets aren't capable of playing the ads, but they'll play the videos just fine, though you wouldn't get any points. You can run the website on a Windows phone, tablet or PC. The plus side is that you can play videos on multiple devices. For example, I have videos running on both a laptop and desktop computer. I leave both computers on and running 24/7.

In addition to earning money passively, you can also boost your earnings by downloading apps, completing offers and taking surveys. In the past whenever I would download apps from Swag Bucks I would almost never receive credit. The same does not hold true for Earn Honey. I am credited for about 90% of the apps that I download, which makes me more like to download them. I generally only leave them open for about 1-2 minutes, then I delete them. Sometimes you'll have special tasks to complete in order to receive credit, such as reaching level 7 in game. Those apps typically pay a lot more. I'll also complete offers that don't require much time.

Supported devices: PC. I'm unsure if it runs on Mac or Linux, but I would suspect it would run on Mac.

Earn Honey has a referral system. Currently you will earn 10% of what your referrals earn for life. The only catch is that your referral earnings won't appear in your account until the 5th of the following month. So if you earned from referrals in September, you won't be credited until October 5th. Click to join Earn Honey

Swag Bucks

Swag Bucks is an all-in-one app/website to earn money. Earlier in the year I was earning $25/week by watching videos, taking surveys, downloading apps and completing various tasks. The currency of points are known as Swag Bucks.

The only passive way of earning Swag Bucks is through watching videos on the app. You can let the videos play while you go about your day. If you use SBTV on your computer, then you'll need to click on every video.

Once you reach 450 SB then you can redeem a $5 gift card. This is the only value gift card you receive a price break. You will receive a price break on a $25 gift card, but that can only be used once a month. Once you have enough SB to redeem, it usually takes up to a week to receive the code in your email. The Swag Store isn't only limited to gift cards, but that's what I prefer.

Referral system: Swag Bucks has a nice referral system in place. You'll earn 10% of your referrals earnings. Join Swag Bucks today

Paid Viewpoint

Paid Viewpoint is a site to earn money by taking surveys. There currently isn't an app available. You earn money by taking short surveys that take less than 2 minutes to complete. The surveys consist of no more than 10 questions. They give you 1-2 surveys daily and you earn $0.10 per survey. There's also a Trait score that earns you points for every survey. The higher your score, the more you'll earn later on. Minimum amount to cash out is $15.

Referral system: There is a referral system for Paid Viewpoint. For every referral you get, you'll earn 20% of their survey earnings once they cash out. In addition, if you become a VIP community builder (more than 100 referrals) then you can earn from your referrals at any time. Sign up with Paid Viewpoint

Supported devices: PC only.

Microsoft Rewards (formerly Bing Rewards)

Bing Rewards is a paid to search and complete tasks website. 95% of your earnings come in the form of PC and mobile searches. You do have various tasks that only require you click on it to earn points. Bing Rewards recently changed to Microsoft Rewards. The currency has changed, so instead of being rewarded 1 points it's now 10. The cost to redeem stuff hasn't really changed too much, except for one aspect. If you were previously a Gold member you could receive a discount on redemptions. Now with Microsoft Rewards that level is referred to as level 2 and they took away the discount.

Microft Rewards no longer has a referral incentive program. 

Supported devices: Android, iOS, PC

Cross Media Panel (formerly Screenwise Trends Meter)

Cross Media Panel is another passive earning app that collects data on how you use your phone, what websites you visit, etc. It is formerly known as Screenwise Trends Panel. Initially when you sign up you will receive $2.00 per device you have installed. You can install the app on a tablet and smartphone (Android, iOS) as well as an extension on Google Chrome, Firefox or Internet Explorer (Google MUST be your default search engine).

After your initial registration period you can expect to earn $1.00 per week for each qualifying device. I am currently earning $3.00 per week with Cross Media Panel. Since the upgrade to Cross Media Panel, they have changed how you are paid your rewards. Previously you had to wait until you earned $25 to request payment. Now you can request it at $5, $10 and $25. You can request payment in the form of gift cards. There is a pretty good selection as far as gift cards go. Amazon, Target, Starbucks, Walmart, Best Buy and Chipotle just to name a few.

Cross Media Panel does not have any referral incentives.
