Simplenote is a cross-platform app/website that has one feature that is especially useful. You can use it to publish a page on the web with a simple click, share the link with your audience, and remove the page just as easily at any time. But it’s far more than that and can be used for a variety of purposes.

Notes stay updated across all your devices, automatically and in real time. There’s no “sync” button: It just works. Add tags to find notes quickly with instant searching. Share a to-do list, post some instructions, or publish your notes online. Notes are backed up with every change, so you can see what you noted last week or last month. Write, preview, and publish your notes in Markdown format. Apps, backups, syncing, sharing – it’s all completely free. Source
