Simply because we have a team that dedicated their life into making great apps for you and the other users to use them daily and enjoy each update that we bring in the App Store. We offer our apps for FREE and our only source of income to pay for server charges, development fee is Ads. However, we make sure that we filter all the ads that get published into our apps this way you won't see any inappropriate ads. We do our best to find a balance between not charging upfront for the apps and still make a living with what we love to do the most.
