TickTick
My go-to app for organising tasks, projects and habit tracking. It’s cross-device and platform (Apple, Google and Windows) with automation support on IFTTT and Zapier so I can manage it from anywhere – mobile, desktop, even smart speakers.
Free to use but I recommend upgrading to Premium for added features and monitoring.
Bear
Note-taking and outlining with Markdown. I love the simplicity of the UX and how I can easily import/export content to web-based apps.
Apple eco-system only but syncs across macOs, iOS and iPadOS seamlessly.
Free to use but, again, premium upgrade unlocks some nice features for a more versatile/customised experience.
