[Who is this for?] - You have too much on your plate and feel overwhelmed - You spend all day firefighting urgent tasks - You want to invest more time in "important but not urgent" work - You've tried other task apps but couldn't stick with them [Key features] - Quick capture: jot down ideas in seconds with the top input - Drag uncategorized tasks into a quadrant - Set due dates and notifications - Review with completion history and weekly stats - Built-in guide explaining the Eisenhower Matrix - NEW: Google Calendar sync (Premium only) Tasks with a due date sync automatically to Google Calendar. Tasks created on iPhone appear on iPad too. [The 4 Quadrants] I. Urgent x Important -> Do now II. Important x Not urgent -> Plan (the most important) III. Urgent x Not important -> Delegate IV. Neither -> Drop [Premium plan] - The free plan allows up to 10 active tasks. Premium lifts this limit. - Google Calendar sync is also Premium-only. (Auto-renewing subscription.

Verdict
The clearest difference is in-app purchases: 優先順位マトリクス at none against QuadTask's 1. QuadTask's advantage is update cadence (every 2 days vs every 2 weeks) and iOS requirement (13.0 vs 17.0). On price, ads and device support there is nothing between them.
