BuildFire is also another great tool to create an app. It is free for 14 days, and is a simple app builder that can help you take your business online. Once you set up your app in BuildFire, you should first make sure that it is a well thought out design and that it is user friendly, as this will generate more positive reviews and therefore more opportunities for a download. Once that is all set up, you can start offering in-app purchases, or start running ads on your app.
