A 360° circular polar dial widget that visualizes your entire day, sub-tasks, and biological circadian rhythm at a single effortless glance. Plan days, weeks, months, or years simply by chatting with AI via the Model Context Protocol (MCP). Zero nagging alarms. Zero task guilt.
Scan with your phone camera to download APK directly to your phone or launch the live dial on mobile without typing.
Past sectors fade quietly into memory. The crimson continuous beacon needle tracks your present moment with polar angular precision. Concentric tracks map sub-tasks, deep sprints, and restorative gaps without turning your day into an overdue anxiety list.
Vertical checklists produce chronic anxiety, overdue red badges, and guilt debt. Radian restores calm situational awareness by mapping time, sub-tasks, and biological rhythms into an intuitive circular dial widget on your home screen.
Vertical lists induce infinite backlog shame. Polar dials close the loop.
Granular items contained within their time block, not scattered across a feed.
Align cognitive demand with neurochemical alertness peaks.
Every routine is an asymmetric tactile card ported directly from the Flutter app canvas. Subtasks float as smooth river pebbles inside your time blocks instead of sprawling out as endless checkbox lists.
Traditional calendar grids collide, truncate, or overwrite overlapping events. Radian's constraint solver partitions concurrent blocks into nested concentric radial tracks (0–1000 level depth), preserving complete situational context.
Connect Claude Desktop, Cursor, or your custom agent runner directly to Radian. Your assistant inspects free gaps, schedules blocks, and pushes updates live to your phone widget over Server-Sent Events.

Inspects active events, remaining duration, upcoming blocks, and active 12h/24h dial mode in real time.
Reads full polar schedule for any target date with start/end angles, color seeds, and nested subtasks.
Identifies unoccupied intervals on the dial (≥15 min) for optimal focus or recharge windows.
Slots an event with title, time boundaries, category, Material 3 hex color, and subtasks.
Atomically plans multiple time blocks in one prompt (e.g. whole morning routine or sprint block).
Wipes and replaces an entire day's schedule with a freshly optimized itinerary.
Pulls sleep debt, resting heart rate, active calories, and recovery deficit telemetry.
Auto-generates an optimal daily schedule aligned with biological circadian alertness peaks.
