Time passes quietly. Memento Calendar makes it visible. See your year as a grid of days. Filled squares show the days behind you; open squares show the time still ahead. No noise, no streaks, no pressure—just a clear view of where you are. Track: • Your year, month, or week at a glance • Custom timelines for projects, seasons, goals, and milestones • Multiple timelines in one calm, focused view • A Home Screen widget that keeps your timeline visible • Dark mode and flexible grid colors • Local-first data with no account required Memento Calendar is for people who want awareness, not another productivity system. It does not ask you to check in, build a streak, or follow a plan. It simply turns time into a visual grid so you can notice it—and choose how to use what remains. Built with Stoic simplicity in mind. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
