Many app developers will give their apps away for free. They will work with a sponsored advertiser and add the ads on the app. Each time a person uses the app and an ad is displayed the company will earn around $0.0001 for the ad. While other app developers will use a snippet code embedded in the app to display a link or redirect the user to another site. When the link is used the company generates money from the company. There are several different ways app developers can generate money from their apps. Most of the ways will be through paid advertisers.
