RayDay: Vitamin D Tracker

Log your supplements, not just your sun. At higher latitudes the sun spends months too low to make vitamin D. RayDay now lets you record what you take on those days, so your daily total reflects both sources. • Log sun or supplements from the Today tab, with a 10-second undo • One daily total, with sun always counted first • History now shows a calendar of your year: gold for sun days, blue for supplement days, and a quieter shade for days the sun was never high enough • Stacked charts break down the last 7 and 30 days by source • Optional evening check-in, only ever on days the sun does not reach 35° where you are • New Reminders section in Settings to turn any notification off • Switch between IU and µg anywhere doses are shown Also fixed: notifications were silently failing to schedule for anyone who had already granted permission on an earlier launch. They work again.
