Next Up: Release Tracker keeps one list of everything you are waiting for. Follow the shows you watch, the films you want to see, the artists you listen to, the games you are waiting on and the teams you follow. Next Up collects every date into a single timeline, soonest first. WHAT IT TRACKS • TV — the next episode, the network, and how far behind you are • Films — release dates, and what you have already seen • Music — new releases and tour dates near you • Sport — fixtures across seven sports, including the cup ties and European nights your league calendar leaves out • Games — release dates across every platform ONE TIMELINE, NOT FIVE APPS Everything lands in one place, sorted by when it happens. Filter it by category or read it whole. STRAIGHT TO YOUR CALENDAR Subscribe once and it feeds your calendar, so new dates appear without you doing anything. TIME WELL WASTED Tick episodes off as you watch them and see what it adds up to — total hours, shows, films, and where the time actually went. QUIET BY DESIGN No ads. No feed. No recommendations you did not ask for. It tells you what is coming and then leaves you alone. Your data is yours: delete your account from inside the app and everything goes, permanently and immediately.
