Gentle nudges help you reschedule or let go — 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 — 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.
