Confirm the download and choose Install.
Rather type the address? Use antenaplay.app/apk, which leads to the same file. The first time, the device asks you to allow installs from Downloader. It's a system permission, and it applies to Downloader only.
Installed it? See How to use for where your IPTV list goes, where your Antena Play account goes and how to subscribe to Pro on your device.
Downloading is free on every device, and the free catalog (public-domain classics and open-licensed shorts) opens with no sign-up and no card. Antena Play is a media player: IPTV lists are the responsibility of whoever adds them.
