I employ the same technique when subscribing to a new app. If I renew it for the second year I have it on auto-renew.
My subscription for this year:
Setapp (still doing monthy review)
Apple Music Family
Apple Arcade (on/off basis depends on the game I’m currently playing)
Prime Video (THE EXPANSE)
Nintendo Switch Online (just for Animal Crossing)
I just realized that this list is 30% shorter than when 2020 started and nothing new was added.
Update (apps I forgot to include on my list)
