iOS: Simplenote has long been one of our favourite syncing notes apps, and the iOS version is getting a little better with an update that adds in support for Markdown. Markdown support works pretty seamlessly. Tap the "i" icon on a note, enable Markdown, type out a note using standard Markdown formatting and then you can swipe to view the Markdown preview. It's a clever integration that's basically opt-in, so if you don't want to use it, you don't have to. Your basic Simplenote experience can go unchanged if you prefer. The update's available now for iOS, and is likely on the way to its other apps in the future.
