J Plan - Daily Planner

J Plan turns your day into a single 24-hour grid. Every hour is one row of six 10-minute cells, so a whole day — 144 slots — fits on one screen. You see how your time is actually shaped, instead of scrolling a list.

TAP AND DRAG ON THE GRID
• Tap an empty cell to create an event; tap an event to edit it
• Long-press and drag across empty cells to paint a new block
• Drag an event to move it, or pull its first or last cell to change the start and end time
• Drop it and choose Move or Copy; for a repeating event, change just this one or the whole series
• Repeat weekly on any set of weekdays, monthly, or yearly

NOTHING EVER OVERLAPS
Two events can never sit in the same 10 minutes. Painting, dragging, nudging, repeating, copying — every path runs the same conflict check, so a slot is either free or it isn't. Events in hidden categories and events synced from your calendar still hold their time, and the grid tells you which one is in the way.

TO-DOS THAT BELONG TO THE DAY
• A to-do list for each day, with an optional time
• Attach a to-do to an event so it follows the event when you move it
• Completed items fade out into a separate Completed list you can undo from
• The badge in the toolbar always shows what is left today

YOUR CALENDAR AND REMINDERS, IF YOU WANT THEM
• Show events from the system calendar right on the grid (read-only)
• Show today's reminders next to your own to-dos, and tick them off from J Plan
• Choose exactly which calendars and lists to include
• Two separate switches — allow one, both, or neither. J Plan is fully usable with neither.

TWO HOME SCREEN WIDGETS
• Today's Schedule, in small, medium and large — the same grid, on your Home Screen
• Today's To-Dos, in small — tap a circle to tick something off without opening the app

BUILT TO LOOK AT ALL DAY
• A warm paper light theme and a real dark theme, or follow the system
• 15 category colours, seven categories to start with, add your own
• Five accent colours, every one tuned to pass AA contrast
• Dynamic Type, VoiceOver labels, and Reduce Motion support throughout
• 繁體中文, English, 日本語, 简体中文, 한국어 — follows your system language
• iPhone and iPad

PRIVATE BY DESIGN
Your schedule lives in one file on your device. There is no account to create, no analytics, no tracking, no ads, and nothing is uploaded anywhere. Calendar and reminder access is optional, read on demand, and never leaves your device.

Worth knowing before you buy in: calendar sync is read-only and does not show all-day events, there is no iCloud or cross-device sync, and events cannot overlap by design. iPhone is portrait only; on iPad the layout is a centred canvas rather than a multi-column iPad design.
