1Password wasn’t built in a vacuum. It was developed on top of open standards that anyone with the right skills can investigate, implement, and improve. Open tools are trusted, proven, and constantly getting better. Here’s how 1Password respects the principles behind the open tools on which it relies:
I found it ironic that this proprietary software that I have avoided using because it is proprietary software is touting the importance of open tools.
Your task list is a plain text file, not some proprietary format owned by a company or locked to a specific application.
Countless productivity apps and sites store your tasks in their own proprietary database and file format. But you can work with your todo.txt file in every text editor ever made, regardless of operating system or vendor.
Most to-do lists give you no control over your data. Your tasks live inside the app, not in a document you can edit, and syncing is handled by whichever company made the app. If you don't like this, todo.txt is a great alternative.
