It appears there is – it’s called Ulysses and it’s what I can only describe as a delightful native app for iOS, iPadOS, and MacOS.
It’s so great, the (rather talented) developers would rather you paid for a subscription.
Subscribe to an app for writing? Really?! It’s a very reasonable subscription (£5 / month), but it still feels weird to pay a monthly fee for an app to write when so many free options exist.
I took the plunge and I am going to see how it performs – if I write more because of Ulysses then it’s easily worth the 2 coffees a month for the experience.
I’m writing this in Ulysses right now and the writing experience on both iOS and on my Mac is just delightful. I love Markdown and I love the balance they've found between complexity and simplicity to make an overall experience that is easy to get started with, but advanced enough to cater to every need I've had so far.
