You and I didn’t ‘buy’ Ulysses.
But yes, I’m in the same boat as you, having already purchased most of the apps in the bundle I’d want to use regularly - CleanMyMac, iStat, Bartender BetterZip, Gemini, iMazing, WiFiExplorer, Elmedia, Boom3D, Forecast Bar, Boxy (didn’t upgrade, though), BetterTouchTool, TaskPaper, 2Do, Cloud Outliner, Marked, iThoughts. (And some of those I bought I don’t use regularly.)
Still, it might be worth it for me to eventually subscribe: I’m still paying $30/yr for Ulysses, which would make it more affordable to get everything else (and not pay eventually for upgrades). And I’d like to play with Pagico and GoodTask on the Mac, as well as NotePlan.
And if Journey is as good as I’ve heard, it could save me an extra $25/year I’m paying for my Day One subscription.
