Yes, most of the time, and if you are in a supported country, you can use a free TV app or service without using a VPN. However, there are upsides to using a VPN for watching content on a free TV app or service. For example, not all available services are 100% safe to use. Safety is something a VPN, even a free one, can help you achieve.  If you are not in a country where this service or app is available, you might have to use a VPN if there are no apps or services that include support for your country. There are loads of free-to-use VPNs that you can use to watch online content, though most of them are not the fastest.
