Yes, there are many free streaming apps available. But most of them are not legal and may be filled with viruses and malware. So, I recommend using only trusted free streaming apps and websites I’ve listed above. If you need more alternatives, you can try:
Crackle (Android and iOS)
Tubi (Android and iOS)
Popcorn Flix (Android, iOS, and Amazon Fire TV)
Vudu (Windows, Android, and iOS)
Showbox (Android, Windows)
