The personal personal productivity app

I’ve been using different apps for productivity for a while, e.g. Todoist, Todo, Any.do, Anylist, Google Keep.<br>The best thing for me is Todoist. I use it for almost everything and it is pretty versatile, but well... it’s not exactly perfect for me.<br>So, I’ve been thinking about building something tailored for me. I’m a developer, so I can do that. But I see that it’s a personal app and personal use. How do you think about it? Do you use a general productivity app or something self built?<br>For example Tom Bilyeu uses ClickUp, which is a great app, but it’s more about project management and personal management. The biggest problem is that the app is (or at least it was, I don’t use ClickUp anymore) not personal enough. I can’t personalise it as much as I want. I can’t build something new, e.g. a to do list with the combination of blocks for notes, tasks, due dates, images, etc.<br>The best app is Notion, but it has some problems. It’s not lightweight, it’s a classic desktop app (well, you can use it in a browser, but it’s not the most perfect app for a web browser). It’s not personal. You can visit the Notion template gallery and use something like Todoist’s template for Notion.<br>The app is not super fast. You can’t really automate (or at least I couldn’t) your tasks with Notion.<br>I think I’ll start developing the app in the coming weeks, but I’m not sure if it’s worth it. What do you think?
