Hangovers can be a helpful warning sign that overindulgence is bad for you. Perhaps this can apply to subscriptions? 
As I noted here, I’m down to just a few subscriptions.
- Apple One Premier
- 1Password
- Backblaze (a new acquisition owing to the kind insistence of forum members)
- MS Office 365
- Ulysses
I’m seriously considering dropping Ulysses. I like Ulysses, but I’m not sure I need it. I’ve moved all of my writing out of Ulysses except for my book project. As an experiment, I’m running parallel versions of the book in Ulysses and Pages (I tried Scrivener again, but I don’t like using Dropbox for sync, and I don’t like Scrivener’s mobile app). I’m discovering that the outline feature in Pages works well, given that I use the styles feature selectively and consistently.
The short version of my thinking is that nearly all of my writing eventually ends up on my blog, as a formal report, or as presentation notes. None of these use cases require an intermediary markdown app. I can easily copy and paste from Pages to Squarespace. It works seamlessly, so I don’t need a markdown editor for the blog articles. As shown in this screenshot, I can use Pages directly for presentation notes by using the “Reading View” mode, which prevents accidental edits.
For distraction-free writing, I hide all toolbars and panels in Pages with two quick keyboard shortcuts. I get this, which is even less distracting than the markdown syntax that is visible in markdown editors:
If I drop Ulysses, I’m left with two subscriptions, which I consider utility subscriptions (Backblaze and 1Password). I’ll drop 1PW if Apple improves Keychain enough or makes Keychain a separate app. This leaves Office. This is paid for by work, so the Office 365 subscription “doesn’t count.” Apple Premier is also a “utility” subscription, in my view. My research files are in DEVONthink, which is a one-time payment.
For my needs, I’m finding I can get by just fine with very few subscriptions. The other advantage is that I have only a few apps to manage and master.
