Is there a product out there for following apps on the App Store and receiving update alerts?

I want to "follow" software and get notified of any new releases. There might be a piece of software I like, but it is just missing a couple of critical features for me to use it. I'd like to get notified of updates and get their release notes. Example - an update when Notion releases a new version. Maybe this app would also have a list of major app updates for that day so we can get a list of fancy features that were released today. It seems like it should be possible to get this data from the app store.
