OWrite Pro brings notes, plans, habits, focus, outdoor workouts, reminders, and important dates into one calm personal space. Write down what matters, take the next small step, and make room to move. WRITE DOWN IDEAS WORTH KEEPING Use rich-text notes for journals, plans, excerpts, drafts, or unnamed thoughts. Add photos, style your text, search your content, restore deleted items from Trash, and turn a note into an image to save or share. BUILD HABITS AT YOUR OWN PACE Choose daily streaks or cumulative targets for reading, stretching, exercise, and more. Set dates, colors, icons, and reminders. Check in with one tap and review progress on the calendar. BREAK GOALS INTO SMALL STEPS Create tasks for long-term plans or everyday work. Set deadlines, reminders, tags, and colors. Divide a goal into scheduled subtasks with checklists and notes, then review progress in week, month, and timeline views. GO OUTSIDE AND MOVE Record outdoor runs, walks, hikes, and rides. Follow your route and live duration, distance, pace or speed, and calories. Pause or resume, mark splits, revisit workout details, and explore distance trends. Supported devices can show an active workout with Live Activities on the Lock Screen and Dynamic Island. Routes need Location permission; Health data requires authorization, and heart-rate readings depend on a compatible device such as Apple Watch. FOCUS WITH INTENTION Create a focus goal and record sessions with an immersive timer. Review daily, weekly, monthly, and yearly statistics. Follow a running timer through Live Activities on supported devices. As a goal nears completion, the timer becomes a countdown and your effort blooms into a mathematical flower. KEEP IMPORTANT DATES IN SIGHT Save birthdays, trips, anniversaries, launches, and other days worth anticipating. See countdowns and elapsed days, choose reminders and recurrence, add a photo or Live Photo, and display a selected date in the Home Screen widget. REMINDERS THAT FIT YOUR DAY Create one-time reminders or repeat them on selected weekdays, monthly, or yearly. Add notes and images, then manage reminders in one dedicated center. ONE HOME FOR YOUR LIFE See habits, tasks, recent notes, focus goals, workouts, and important dates together. Search titles, content, and tags or filter by color. Completing habit, task, and focus goals unlocks distinctive Maurer Rose achievements.
