4ToDo rethinks how you manage your life. Instead of boring checklists, every task, routine, and goal is a visual progress bar โ€” you see exactly where you stand at a glance. TASKS โ€” ORGANIZED BY CATEGORY Create categories like Home, Work, Tech, or Travel. Each category shows a bold progress card with a colored accent bar and a live percentage. Tap into a category to see all tasks sorted by due date. Add subtasks to break down complex projects โ€” the progress bar fills as you check them off. ROUTINES โ€” NEVER FORGET RECURRING TASKS Track recurring maintenance tasks like reading the electricity meter, changing filters, backing up photos, or rotating tires. Set intervals from daily to yearly, or define a custom cycle (every X days). Each routine has its own color and icon. The urgency fill shifts from calm to amber to red as the deadline approaches. One tap to mark it done and reset the timer. GOALS โ€” THREE WAYS TO TRACK Set personal goals with the tracking mode that fits: - Counter โ€” Big +/- buttons for step-by-step tracking (books read, recipes cooked, trails hiked) - Value โ€” Enter custom amounts (kilometers run, hours practiced) - Slider โ€” Drag to set your progress visually Add milestones to goals and tap to mark them as reached. The app automatically updates your progress when you hit a milestone. RADAR โ€” YOUR COMMAND CENTER The Radar page answers one question: What should I do next? It shows your closest goal at the top, overdue items that need attention, and a unified timeline of everything coming up over the next 14 days โ€” grouped by day. Tap any item to open it. Hit the checkmark to complete it instantly. A weekly momentum heatmap shows your activity pattern. BUILT FOR RELIABILITY - Automatic backups every 7 days, plus manual backup on demand - Import and export your data as JSON - Restore from any of your last 7 backups - Local notifications with reminders for tasks, routines, and goals - All data stored locally on your device โ€” nothing leaves your phone DESIGN PHILOSOPHY 4ToDo uses a striking dark theme with yellow accents and 8 category colors. Every element communicates status visually through progress bars. No clutter, no complexity โ€” just a clear view of what matters. Built by robspace.

JustStart

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.
