Hello fellow patient gamers, this is a cheeky self-plug for !freegames@feddit.uk, a community I've created to post limited-time full-game free giveaways. The reward for being patient is that sometimes you get freebies; post them here if you spot them first, or comment to say whether it's a must play for everyone or if zero cost is still too expensive!
You can use one of the bunch of RSS feed readers to do that. I haven't use it for years (basically since I lost everything I had on Google reader) so I cannot recommend you any apps
I tried subscribing to the RSS feed and it loaded the initial content but then never updated, have you had better luck with this or is it a bit buggy in general?
