Since making the decision to engage less in social media I’ve become a big fan of RSS again and have my reader of choice NetNewsWire installed across all of my iOS devices.
I started curating my feed on my iPhone only. Once I was happy I then used the export option to save to my iCloud.
On my iPad I then use this export to sync my feed. When I add new feeds I export and reimport again. The only issue with this is that when you reimport you’ll need to remove all of your subscriptions first or you’ll have duplicates.
I know this isn’t perfect but is free and saves a sign up to an RSS management app.
