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 โ€” 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 โ€” 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 โ€” 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. Payment is charged to your Apple ID account at confirmation of purchase. The subscription automatically renews unless canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions in your App Store account settings.

The hardest part of having ADHD isn't understanding what to do โ€” it's starting. JustStart is built around one simple truth: the smaller the first step, the easier it is to begin. Break any task into pieces small enough to actually start, then use a body doubling timer to keep your focus going. TASK BREAKDOWN โ€” START IN 3 SECONDS Add a task, hit "Break It Down," and JustStart splits it into micro-steps you can actually begin. No more staring at "write report" on your to-do list. Instead: "open document," "write one sentence," "find one source." The first step is always achievable. BODY DOUBLING TIMER Body doubling is one of the most effective focus strategies for ADHD brains โ€” working alongside someone else (even virtually) dramatically improves task completion. JustStart's body doubling mode pairs you with focus sessions so you're never alone in the struggle. HYPERFOCUS ALARM ADHD hyperfocus is a double-edged sword. JustStart's hyperfocus alarm gently interrupts you after a set time โ€” reminding you to eat, move, or switch tasks before hours have vanished without you noticing. ADHD-FRIENDLY DESIGN No overwhelming dashboards. No endless lists. JustStart shows you one thing at a time โ€” the very next step you need to take. Minimal visual clutter, high contrast options, and large touch targets make it accessible when your brain is already at capacity. FOCUS TIMER WITH FLEXIBLE INTERVALS Whether you prefer 25-minute Pomodoro blocks, 10-minute sprints, or custom intervals, JustStart's focus timer adapts to how your brain works โ€” not how productivity gurus say it should work. WIDGET โ€” YOUR NEXT STEP, ALWAYS VISIBLE The JustStart widget shows your current task's next step directly on your home screen. Glance, tap, start. No unlocking, no navigating, no decision fatigue. STREAKS BUILT FOR ADHD BRAINS Traditional streak systems punish one bad day and reset everything. JustStart's streak system is forgiving by design โ€” rewarding consistency over perfection, and celebrating effort rather than output. REMINDERS THAT ACTUALLY LAND Smart, non-repetitive reminders that vary their message and timing so your brain doesn't tune them out. Because the fifteenth identical notification is invisible to an ADHD brain. JustStart is for adults and teens with ADHD, ADD, or anyone who struggles with task initiation, executive dysfunction, time blindness, or chronic overwhelm. You are not lazy. You just need a different kind of start. Free tier: 10 active tasks, basic focus timer. A subscription unlocks unlimited tasks, body doubling sessions, full focus history, custom hyperfocus alarm profiles, advanced widgets, and detailed productivity insights.
