If this were available on macOS as well, and did sync via iCloud I'd be all over it. It's a great model for a calendar/task manager but I really don't want to have to squint at my phone screen while using it.
Thanks. I'm happy to share that iCloud sync and MacOS app is something that already in the plan for future development. In the meantime, if you have an M-series Mac, you should be able to run the app directly on your Mac since I've enabled Mac Catalyst support.
When I open this in the Mac app store, there is a download button, so I'm guessing it works on both iOS and macOS due to catalyst.
Look into NotePlan.co it syncs with iCloud and has native MacOS and iOS apps. I love it.
If the developer checked the enable the Mac Catalyst destination in the Xcode project, you should be able to run it on your Mac.
