Most market apps show you prices. This one shows you time. World Stock Market Clock tracks when 60+ exchanges open and close, in your local time, and reminds you before the bell. Live Activities and Dynamic Island put the countdown on your Lock Screen, with Home and Lock Screen widgets too. It handles the parts people get wrong: exchange holidays, early closes, half days, and daylight saving shifts that don't line up between countries. No account, no tracking, no stock picks.
