What if you could only use ONE APP on your iPhone?

So this is a completely random but fun experiment… but what app would you pick if you could only pick ONE?

I know, I know. It’s an impossible choice. I’d be so torn between several: camera, notes, music, messages, tasks…

And, as nerdy as it sounds, I think I’d pick the app Things. (The to-do list manager.)

Things is not my most used app at all. But… it’s super fast, very easy to use and navigate, and very versatile. I think it’d work as the single spot to keep all my ideas, reminders, projects, tasks, notes, etc.

I think I’d prefer the simplicity and speed over the missing features.

If it was a different device — say iPad or Mac, I’d pick a different app. I’d probably pick Ulysses as the only app I could use on my iPad. And Notion as the only app I could use on my Mac. (Or I would totally cheat and say Safari on Mac.)
