I Was working on Sketch, it crashed and deleted everything I'd done. Any chance it can be recovered?
I'm sure you've figured out some of your "SAVE" solutions for Sketch by now. When creative apps get so engaging that we forget to hit the save key, it's one thing, but Sketch doesn't have a 'save key' like desktop Photoshop.
MY SAVING SOLUTIONS FOR SKETCH
Obviously, there's no CMD/CTRL+S for the app. So you have to rely on other ways to avoid losing work due to iOS crashes.

These don't help you get the data back from your crash point, but at least you can get back to a recent save point. I usually save every 20min on desktop. I'd probably shorten it to 10min on iPad... when I remember.
