I believe Safari's new prevention of cross-site tracking prevents SubToMe from remembering the user's application choice (or any other data), e.g.
If I navigate to subtome.com/#/settings I can see my application choice is FeedHQ, however, on any https://example.com, clicking the SubToMe subscribe bookmarklet results in the default choice of Feedly, The Old Reader and Feedbin, or to view the full list of services.
Viewing the full list, then selecting FeedHQ on example.com will result in the preference being remembered on example.com but not other sites. (Obviously this isn't very useful since theoretically the user only subscribed to a specific site once.)
Maybe another approach could be to allow the user to choose their application on subtome.com which then configures the bookmarklet with a hardcoded URL?
