RelaxMinder is a visual reminder that brings together what you want to remember with the year’s big picture and a clear view of what’s next. The Spiral Timeline shows the entire year on one screen; the Linear Timeline makes nearby events and potential overlaps obvious. This way you instantly see what is coming when, where things stack up, and how to balance your plan. How it works • Spiral Timeline: See your reminders across the year on a single spiral. Instantly spot busy periods, gaps, and seasonal cycles. • Linear Timeline: Track what’s next in chronological flow. See overlapping reminders and resolve conflicts quickly. • Rich Reminders: Add notes, images, and files to any reminder so context and materials are always at hand. • Reminder Types: Birthdays, one-time or repeating/multiple reminders; shopping lists; medication and water-intake reminders—stay organized with types that fit your daily flow. • Calendar Integration: Works in sync with iOS’s native Calendar app; view everything together to keep your schedule consistent. • iCloud Support: Archive reminders to iCloud and keep them in harmony across multiple devices. What it delivers • Focus on the near term without losing the big picture: See your year-long plan and catch what’s coming at a glance. • Detect conflicts early: The linear view keeps items scheduled for the same date/time from slipping by. • Work with rich content: notes, visuals, and files make each reminder self-contained. • Flexible use: from special days to health routines, from shopping to projects—adapts to different needs. • Reliable sync: with Calendar and iCloud integration, your plan stays up to date on every device. Use cases • Birthdays and anniversaries: See what’s approaching in the spiral and prepare before the day arrives. • Daily routines: Stay on track with water and medication reminders. • Work and personal projects: Attach documents/files to a reminder; keep meetings, deadlines, and checklists in one place. • Shopping: Link a list to a reminder; add photos and notes to get the right item at the right time.
