It's a calendar app (like Akiflow and Motion), it's a task app (like Todoist and Tick Tick), it's a full Notion-style PKM. This is what I've been looking for since forever.

There are very few apps that have even attempted -- much less succeeded -- in meshing this combo together in a workable system. Amplenote comes to mind (sophisticated app, but a clunky UI makes it hard to adopt), and maybe NotePlan, but other than component systems (Notion or Obsidian with a basketload of plugins) that's about it.

I discovered ByDesign last year and purchased the LTD right away and have loved it ever since.

Of course it's not perfect -- I've experienced a few hiccups and bugs along the way, pretty much to be expected with new applications. And it's individual components are made to work together, so don't expect the tasks feature to equal Todoist, or the calendar to rival Morgen, or the notes app to be as full-featured as Notion. But as a fully-functional, self-contained PKM ecosystem ByDesign is a marvel, warts and all, and for $79 it's an absolute steal.

Cons (that aren't so much cons as personal grumbles): the Dashboard is a nice feature, but it's not as interactive as I would like. I'm impressed that they even HAVE a dashboard (more of a CRM or Project Management convention) but I wish it spotlighted Quick Capture better. Most task or planner apps simply have an Inbox, and while ByDesign does too it's buried behind the Pages tab instead of on the Dashboard. And that's JUST for tasks -- what if you want to take a quick fleeting note? If you hit the plus (+) on the Dashboard you only get the option to add a task, and it goes directly to the Today section. Same on mobile.

So basically I just default to my own Daily template where I capture most of my on-the-fly notes and tasks and go to my own Daily Journal template to journal. An easy enough workaround, but why? I think ByDesign is missing a huge opportunity here by not including a Quick Capture feature (+ sign followed by Note / Task / or Event) and a Daily Journal option by default. It could not only be a selling point, it will make it a lot easier for people who want to migrate away from Todoist, or Akiflow, or DayOne, but don't want to DIY a productivity system all by themselves. Just my 2cents, your mileage may vary.
