Sometimes the benefit of an app is in some of the nuance of its interface.
For example, @SteveNY uses Notes for all his text, including stuff he would have otherwise used Day One or a text editor for. I couldn’t use Notes in this way, it’s too much of a combination of contexts with no personally satisfactory way of organising and filtering all that stuff. Day one gives me additional contextual data about the setting in which the entry was written/added, and has a calendar-focused approach to accessing your stuff.
Notes is totally capable, but Day One works better for me. You could make Bear work for the same purpose, or just keep plain text files in a folder/tag structure, but it’s often great to have modality that supports the nuances of your task.
For this reason, perhaps counterintuitively, I use the app Bear for longer forms of writing, and not for notes, while it sells itself as a notes app. I do use Notes for notes because it’s last-edited folder structure and sharing features really work for me for that task.
I do however use a minimum number of apps. I make use of almost all the stock apps, and only have a handful of others installed. Discounting of course those super specific apps such as my banks’ apps. I don’t use much in the way of automation apps such as Hazel or TextExpander because I really have no use for them. I can see why for specific people they’re great but for me they’d be a solution in search of a problem.
I’ve never had the compulsion to try alternative e-mail apps, or alternative task managers. Mail is more than capable. I have my e-mail so locked down that I don’t receive much spam (and Apple catch 99.99% of that). I don’t have any newsletters or advertising mails at all. All the email I get is necessary and worth my time. It took a bit of effort to get to that point, but it’s far superior to using a service like SaneBox, I totally get why other people turn to it, but it’s possible for someone sufficiently motivated to make SaneBox redundant, if that expenditure of effort is more valuable to them than the SaneBox subscription.
At work, I have many Outlook mail rules that literally redirect more than half my incoming mail directly to the trash. I’m super not sorry and don’t care one bit if someone feels that I missed their important e-mail.
Wow, I rambled.
