Welcome to RSN!
Really Simple Notifier is, as you may have guessed from the name, a really simple RSS notification platform.
This is not an RSS reader. Instead of showing you the feed content the title and URL are extracted and turned into a link to take you to the actual content. Why read a simplified version when you can just go to the real thing?
Unlike many RSS readers RSN does not waste your device resources (battery for example) constantly pulling new copies of all your feeds looking for updates. Instead my server does it for you. :P The server is constantly walking the list of feeds keeping track of which ones have new content. When you want to see if you have new stuff, you can check one place and get a list of everything that is new! When you are actively using the site it will poll the server every little bit, resulting in you seeing your new content within minutes of it being posted. Best of all, when you read something all your devices will know you read it, unlike a traditional RSS app where each instance is independent.
Content is tracked by URL. If the URL of old content changes it is assumed to be a new (thankfully sites that do this are rare, otherwise I would have to hash the article contents or something like that). The server has an elephant's memory, it will never forget what you have read, so if you are subbed to one of those annoying sites that list every single page on the whole site in their feed you won't get bombed with hundreds of "new" articles every month when the RSS service throws away "stale content" (a purely hypothetical situation that had nothing to do with me making this in the first place. Yup, purely hypothetical).
In previous versions of the project it would actually notify you of new content via a browser extension, but this version does not have anything similar implemented. I debated using push notifications to alert you to new content, but ended up not doing it for this iteration of the app. Maybe in the future?
This project was made for my personal use. I use it every day for all my reading needs, so it should be pretty reliable. That said, sometimes stuff breaks. If it does use this handy little email link to let me know what is wrong. I'll have it working again shortly. This isn't the product of some big corporation, its all one dude who likes webfiction and comics and couldn't find a good way to handle RSS feeds across devices that didn't have a subscription fee and/or missing required features. Usually both.
Anyway, if you want to give my little project a try you can sign up at any time.
If you are one of those light-mode weirdos click the sun in the bottom right corner. Pardon me, I'll be over there commiserating with your eyes.
