While sticking notes on your computer monitor is a fast and straightforward method, it can be obstructive, ensuring you never overlook your reminders. However, this approach isn't ideal for modern Macs with their slim bezels. On the other hand, your Mac's menu bar often has unused space—why not repurpose it as a digital sticky note?
With One Thing, a minimalist app, you can effortlessly jot down reminders directly on your menu bar. Simply click the app anytime to leave yourself a quick note.

Type any message you like, and it will appear on your menu bar. You can include emojis for added emphasis or utilize Markdown, a straightforward formatting tool, to style your text or insert clickable links. As the app's name suggests, you can only leave one note at a time—ideal for keeping your focus on your current task. It’s equally effective for reminders or even a motivational message to yourself.
You have several customization choices: adjust the maximum width, font size, and color. You can also modify the alignment, which is useful if another app’s text doesn’t align perfectly with One Thing.

You can configure keyboard shortcuts to open the editing window, erase the current note, or paste content from your clipboard directly to the menu bar.

Other quick note-adding methods include support for Apple's "Share" menu and Apple Shortcuts, allowing you to automate text transfers from your to-do list app. The developer even provides an example shortcut to fetch the next task from Things.
Even if you ignore these advanced features, the app remains highly useful. At its core, it’s a straightforward tool for placing reminders in a spot you can’t possibly miss.
