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.

> Some chores only come around once or twice a year โ replace the water filter, > service the car, test the smoke alarms, bleed the radiators. They're easy to > forget and expensive to ignore. Due Again keeps every one of them on track. Due Again is a calm reminder app for the infrequent, recurring maintenance that keeps a home, car and garden in good shape โ and it lets your whole household share the load instead of leaving it to one person. Add a task once, choose how it repeats, and Due Again does the remembering: โข **Schedules for anything that recurs** โ fixed dates (every 12 months), "X months after I last did it", or simple one-offs. โข **Reminders that reach you in time** โ set how many days of lead time you want, then snooze or skip an occurrence without breaking the schedule. โข **Organized by category** โ Home, Car, Garden, Personal and Other, so the right jobs are easy to find. โข **A clear completion history** โ see what was done and when, with notes, so nothing is guessed at or done twice. โข **Share with your household** โ invite family or housemates as viewers or editors with a single link, and everyone sees when a task is marked done. โข **Stays out of your way** โ archive what you no longer track and keep your list focused on what's next. Due Again is free to track up to 4 tasks and share with one person. **Due Again Pro** unlocks unlimited tasks and unlimited household sharing โ available monthly or annually, so it can keep earning its keep with reliable reminders, sync and new features. Stop trusting your memory for the things that matter twice a year. Let Due Again tell you when they're due again. EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
