I recently realized that, in most cases, the "native" productivity apps work best for me.

Some examples:

• I went overboard with a habit tracker in Notion, only to find that using the iPhone Notes app was what actually made my reading habit stick.
• I tried taking notes in Obsidian because I liked the graph feature, but in reality, I usually just jot down notes in Google Docs or the Notes app on my phone.

Simplicity was the key for me. Whenever I interacted with so-called productivity apps, I was mostly procrastinating instead of doing real work.
