DropScout

DropScout alerts you when Amazon prices drop!

I know you're not supposed to shop on Amazon, but if you do, you should at least save a few bucks. DropScout is a new app for iOS and iPadOS (that runs on macOS as well), does not need an account and alerts you on price drops. It's still a bit rough around the edges, but it's free. Think about it as more privacy respecting version of camelcamelcamel for your phone.
