My daily apps from SetApp:

    ‣ HazeOver (dims any window without focus by a simply-configurable amount)
    ‣ Mosaic (window position/size management), TextSoap (quick text-cleansing recipes)
    ‣ Timing (track time spent in all apps/paths for client billing)
    ‣ Marked (Markdown editor with live preview)
    ‣ Paw

I also use:

    ‣ Gemini (dupe file finder)
    ‣ Chronicle (bill organizer)
    ‣ NetSpot (wifi analyzer)

For me, it's definitely worth it.
