New in 1.2 • Your shifts in the iPhone Calendar. Turn it on in Settings → Calendar and each shift becomes one event in a "Vessa" calendar you can share with the people at home. • Share your next four weeks as one page, as an image or a PDF. • Widgets for your Home Screen and Lock Screen: today's shift and your next sleep. • A note on any day: where you're working, who you're with. • The DuPont rotation joins the shift templates. • Reminders on days off: switch it off and your days off stay quiet. • Sleep reminders now say which sleep and when. • If you deleted your account and came back, Vessa reconnects your subscription for you. • A Support ID on the About screen, to quote when you write to us. Plus fixes: a purchase that doesn't go through now says so on the paywall.
