Because smartphones are everywhere, the demand for new and creative apps is increasing in popularity more than ever before. Between Google’s Android and Apple’s iPhone market, people are using countless apps everyday. And, most of them are selling right and left. Taking the time to develop and sell a smartphone app may be worth your while since it’s a very lucrative way to earn money online. The apps cost almost nothing to actually develop and don’t involve any shipping or storage costs, which works to expand your overall profit margin. Well performing apps can make thousands in ad revenue each month for their creators, making them another great passive income strategy.

For some people, work just has to be in an office, factory, store, or any other environment that’s separate from home. Even a second job would have to be in a separate place. For others, a home office is a welcome place for a secondary or even a primary job. If you’re one of those people, you have some unique opportunities, but you also have some very particular challenges of working from home.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Like Airbnb, becoming a ridesharing driver for companies like Uber, Lyft or Sidecar is a way to join the shared economy. And though it is not technically earning money from home, it allows the same kind of flexibility and it is a way to use an asset you already own (i.e. your car) to make money. There are things to keep in mind, though, about driving other people such as whether your car insurance will cover you and how you pay taxes on your earnings.
Work as an online interpreter or translator. If you’re fluent in a foreign language, it makes sense to look for work as an online interpreter or translator. Depending on your individual skillset, you could find work translating blog posts or eBooks, transcribing recorded lessons or speeches for clients, or translating through Skype or another online video service. And, thanks to the increased use of foreign languages in the United States, getting started could really pay off. According to the Bureau of Labor Statistics, employment for interpreters and translators is expected to increase 17% nationally through 2026.
There are quite literally hundreds of clever ways to make money online. From taking online surveys, to renting or selling your old clothes, flipping your iPhone to someone in a different country, and even buying low-cost products locally, just to resell them for a higher price on Amazon. There’s truly no shortage of unique ways to make money online.
Create a stylish and functional website. Elegant or funky, classical or hipster, your online store should reflect what you’re selling. No matter what your style is, it's important to give off a professional air. Since you won't be able to earn people's trust in person, your website will have to do the selling for you. Your site should be engaging, and most importantly, easy for customers to use when they're ready to make a purchase.
Drive for Uber or Lyft: If you're in a locale where you can find Uber or Lyft (or even one of the many competitors around the world such as China's Didi), you could easily make a respectable income. The hours are flexible and you can work as you see fit, making it perfect even if you currently have full-time employment but are looking to make some money on the side.
The money is most certainly in the list. If you're at all interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list. It's often said that you can expect to earn about $1 per subscriber per month. If you have a list of 10,000 subscribers, that means you can earn roughly around $10,000 per month. You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
