YOUR DAY, MADE CLEAR Prism is a visual day planner that helps you see your time, not just your tasks. Color-coded blocks show your entire day at a glance β what's now, what's next, and what's done. BUILT FOR HOW YOUR BRAIN WORKS Most planners are built for people who are already organized. Prism is built for everyone else: - Time blindness? See exactly how your tasks fit into your day - Overwhelmed? Prism shows you just the next thing - Tasks piling up? Gentle nudges help you reschedule or let go β no guilt, no shame SMART WITHOUT THE CLOUD Type "Gym at 5pm for 1 hour" and Prism understands. On-device AI parses your tasks, suggests icons, and picks colors β all privately, nothing leaves your phone. CALM BY DESIGN - Warm, muted color palette (no angry red alerts) - No streaks, no productivity scores, no guilt - Overdue tasks get gentle options, not punishment - "Plans change" is a feature, not a failure SUBSCRIPTION INFORMATION Prism Pro is available as a monthly or annual auto-renewable subscription.

Verdict
The clearest difference is in-app purchases: SimplePlan at none against Prism's 2. Prism's advantage is update cadence (every 5 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
