@colinwalker I made the switch too, even though I have previously purchased each version (mac, iOS and even the old Daedelus Touch).
I like the app, and want to support the developers.
@colinwalker further to my previous comment, I anticipate "subscription fatigue" wherein I will only be willing to support a certain number of subscription commitments. For now it's Ulysses, 1Password and Text Expander as my keepers.
Devs need to consider finite opportunities
@desparoz Absolutely. The next version of Drafts will also be on tiered subscription so I'll no doubt sign up but, beyond that... A small monthly fee suddenly becomes a large undertaking making it a much more competitive landscape.
