Ranked in these QuestionsQuestion Ranking
Pro Extremely simple to use
Does a scan, shows a list of apps (which can be filtered to exclude apps from the App Store, or only show apps with an update), then there's an update button for each app that has an update.
Pro One-time payment
It's fairly cheap, and it's not subscription-based.
Pro Shows detailed information about an update
You can see release notes or changelogs (if available), and also the source of the information that is displayed. That is very helpful when considering whether to apply or ignore a specific update.
You can ignore entire apps, or just one specific update for an app, so you can clean out your to-do list of updates.
Pro Application updates can be done from within the app
There are several options for the individual apps, among which "Update app" is very pratical.
Pro Scheduled scans
You can set MacUpdater to scan for updates on a regular basis, e.g. weekly, so that you don't need to scan each app separately. The more apps you have, the more time (and attention) this will save you.
