If you a regular IPTV user, you might know that all the IPTV providers won’t have the built-in streaming app. IPTV providers like Marvel IPTV won’t provide you the app to stream its content. You have to install any third-party media player apps. One such app is the Flex IPTV app. With Flex IPTV, you can get to stream IPTV contents via the M3U URL.
Some IPTV services provide you the M3U URL instead of login credentials. With the M3U URL, you can stream all the live TV and on-demand content. As of now, the Flex app has the support for M3U URL alone. If your IPTV provider has login credentials, then you have to choose other IPTV players. Flex IPTV supports all the IPTV providers with the M3U URL. As the app is available for free, there is no need to buy a subscription. You can directly install the app on your smartphones or streaming devices.

Opinion
As the app is available for free, you can install and try the app without second thoughts. If you aren’t satisfied with the built-in IPTV player, you can go for the Flex IPTV. The only missing thing in this player is the lack of support for IPTV login credentials. If your IPTV provider has only the login credentials, you have to look for other IPTV media Players.
