Yet this time, for some reason, I stopped myself. In recent years, Twitter and much of the rest of the internet have been getting hotter, more reflexively outraged, less fun. Venturing onto social media these days, I often feel like a cat burglar stepping through a field of upturned rakes. I could imagine my dumb joke getting picked apart for all the ways it was problematic — “New York Times writer casually encourages bestial sexual assault! #deertoo” — bringing me ever closer to cancellation. I remembered I was supposed to be spending a nice weekend in the woods with my family; why risk days of online drama for a stupid tweet?

And so, instead of sharing the silly lampshade joke, I journaled it in Day One, a magnificent digital diary app that has transformed my relationship with my phone, improved my memory, and given me a deeper perspective on my life than the one I was getting through the black mirror of social media.

Think of Day One as a private social network for an audience of one: yourself. You post updates to it just as you might on Instagram or Facebook. The app — which runs on Macs, iPhones and iPads, syncing your entries between your devices — can handle long text journals, short picture-focused status updates, and pretty much anything else that comes across the digital transom.

I use it to jot down my deepest thoughts and shallowest jokes; to rant and to vent; to come to terms with new ideas I’m playing with, ideas that need time to marinate in secret before they’re ready for the world; and to collect and reflect upon all the weird and crazy and touching artifacts of life in this bracing historical moment: screenshots of texts with my wife, audio recordings of my kids singing in the car, dumb jokes from my work Slack, and so, so, so many selfies.

But Day One differs from social networks in one key way: It’s unsocial. Indeed, it’s downright antisocial. Nothing about the app is meant to be shared — it is protected with your Apple security credentials and backs up its data to the cloud using end-to-end encryption, so that the only way someone can get into your diary is by getting hold of your device and your system passcode.
