If you have a good idea for an app, and the skills to create it, then producing your own premium app can be profitable. However, with so many free apps available, it may be hard to convince people to pay. If you want to go down the premium app route, consider having a basic free version to encourage people to download the app in the first place. You can then provide the option of upgrading to a premium plan once users realize how useful the app is.
I have been making money online for over a year now. Not in the big time yet, still consider myself to be learning my craft. I was doing it really ineffectively (using adsense and amazon along with a t shirt affiliate deal) and driving traffic almost exclusively though facebook.

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. 
Similar to e-commerce websites such as Amazon and OLX, a peer-to-peer (P2P) platform is a marketplace for money lending activities. You can lend money to others in a more organised and structured manner using the P2P lending platform. The P2P platforms have the recovery process in place and one should understand it before using the services of the platform. Since this is an unsecured loan where there is no face-to-face interaction, a P2P lender needs to be aware of the risks involved. Currently, the interest rate earned can be anywhere from 13 percent to 30 percent.
