Only Breaking news appHow will your app be unique? FB campaigns may get you installs but active users get you the ad revenue. If there's nothing special about your app, they'll uninstall the app and you'll keep burning money on FB ads to get more installs. There are a ton of news apps now, I hope you know what you're doing.
Thank youthere are many major news apps and website already out unless you are target a specific niche I don't see how you can compete with real newspapers that have a team of writers on staff.
