Tubi TV has had a Fire TV app since the device launched back in April last year. Today they’ve released a new replacement Tubi TV app for the Fire TV and Fire TV Stick. The new app is listed separately from the old app, so if you already have Tubi TV installed it won’t automatically update. You’ll need to manually install the new app. Tubi TV claims to have the largest collection of free TV shows and movies. They add content every week, but given that it’s all free, be prepared for older movies and lots of ads. The new app has a cleaner interface with better categorization to help you sort through their library of free content.
