Both types of applications that you would see in most stores application is a free application and application PAID. Many applications are available for download free of charge which raises the question came clear how to make money if my application is free? There are two main streams of income for offering the application free of charge.
The first is the ad that relies on targeted ads such as Google Ad Sense or affiliate links inserted into the application content. No one wants to have a mess ad content so it is important to place them in areas that will be considered, but not so much that they get in the way. Another option is to offer a free application, but hold a particular feature or function that will attract users and attract them to consider buying the full version.
If you go down this route it is important to not put all your eggs in one basket so to speak. If you offer too much in the free version users will not need to buy. As there is no rule to say you cannot use both options at the same time. If you want to fill your application directly to make sure you set a fair price that is realistic. Costs too much and you price yourself out of the market. Charge too little and you run the risk of devaluation your application.
