There are many, many ways to keep a journal using your various iDevices, or paper, or even — if you’re desperate — your Android phone. (Kidding — a sharpie turns the back of any Android handset into the perfect paper-emulation device.) But they tend to be either high on effort — manually writing up everything yourself — or somewhat proprietary, keeping all your info inside an app or service.
But thanks to the ever-amazing internet automating service IFTTT (If This Then That), and some new channels, it’s now possible to roll your own plain-journal, pulling from various sources automatically. And it even includes pictures, which is quite a trick for plain text.
