The app stores created an opportunity for any developer to build their own products and reach a global audience with them. For some developers this offered the promise of an independent app business, giving them creative control of their work and hopefully a comfortable income.

In an earlier post we showed how enterprise app developers make 4 times the revenue of those developing consumer apps on average. Targeting enterprises with apps can be very different from building consumer apps and not all developers prioritise revenue, so it’s not for everyone.

Do you want the indie developer lifestyle, or to build a company? What sort of contact do you want to have with your customers?

The mobile apps business is maturing and while most of the media attention is still focussed on the latest app store success stories, developers are finding lots of better ways to make revenue with their apps.
