I use Astro on macOS, iOS, and Android. Insights to one-click to unsubscribe and auto-archive old emails. Mail scheduling. Follow-up reminders. Question detection. The best priority inbox I've used ever. Snooze to Desktop(!!) And it's FREE!

Standard artboard sizes for Material Design in Sketch are 360x640, but the 5X, 6P, Pixel, and Pixel XL all actually render at 411x731.

I set artboards to these dimensions @1x for designs and use Crystal on my phone for pixel perfect results.
