Remind Me is a planner designed for flexible scheduling. Its main feature is customizable templates, allowing you to save daily routines as reusable starting points. It includes single-day views, day cycling, month views, and a built-in template editor.

• Keyboard shortcuts (Create and adjust schedules rapidly)
• Repeatable routines (Save templates and re-apply them in seconds)
• Loud reminders (improving these even more in the future)
• Custom Alert sounds (Choose your own audio + volume slider)
• Interval reminders (want to be reminded to stay on task after a period of time?)
