"2Do adapts to my needs, not the other way around. 2Do gets me." — MacStories 2Do is a to do list, task manager and daily planner in one, with a simple, fluid interface wrapped around a deep and flexible set of features. Keep a quick checklist, run a full GTD® system, or anything in between: there is no wrong way to use 2Do, and it never forces a methodology on you. One-time purchase. No subscription, no account to create, no strings attached. TYPE IT THE WAY YOU'D SAY IT • New: natural language input. Type "Call the dentist tomorrow at 3pm #health" and 2Do fills in the due date, time and tag as you type • It reads dates, times, repeats, alerts, durations, priorities, tags, lists and saved locations, in English, German, Spanish, French, Italian, Dutch, Japanese, Korean, Chinese and Russian CAPTURE ANYTHING, FAST • Quick Add: touch and hold [+] and file task after task, with dates, tags and lists as you type • Siri & Shortcuts: add tasks by voice, or wire 2Do into routines that do the whole job • Widgets, Lock Screen and Control Center, so capture never waits for the app • Mail to 2Do: your device gets a private email address, and anything you send it lands as a task, checklist and all • A GTD® Inbox for everything not yet sorted SIMPLE TASKS, OR AS MUCH MORE AS YOU NEED • Start with a task, grow it into a checklist or a project with sub-tasks • Notes in Markdown, styled as you type, with links collected for you • Flexible repeats, start dates that hide tasks until they matter, durations, and actions that make the next call or message one tap away • Attach images and voice notes SMART LISTS: SAVED SEARCHES WITH SUPERPOWERS • Search across titles, notes, tags and dates; sounds-like matching finds it even when you can't spell it • Save any search as a one-tap view: your weekly review, stalled projects, errands nearby • Focus filter: set a rule per list and one tap hides everything that can wait TAGS THAT SORT EVERYTHING • One tap on a tag filters your day to that context; Tag Groups keep big collections tidy • Pause a tag and every task carrying it steps out of view, hidden, not deleted, until you're ready NEVER MISS A THING • Stack multiple alerts on a task and let 2Do nag until it's done • On iOS 26.1 and later, an alert can ring like a Clock alarm: full screen, through Silent mode, until you answer • Nearby: location reminders that fire when you're close enough to actually do the task • See your calendar events right above your tasks, so plans never collide SYNC YOUR WAY Most apps decide where your data lives. 2Do thinks that's your call: • iCloud: uses the account already on your device; syncs tasks, Smart Lists, tags, groups and attachments • Apple Reminders: your tasks live in Reminders too, so Siri and everything that reads Reminders can see them • Todoist: connect your account and run your Todoist projects right inside 2Do • Dropbox, Toodledo, Fastmail, or any CalDAV server you trust, including one you run yourself • When two devices meet, 2Do can merge them instead of making you pick a winner • 2Do for Mac is available separately, so your lists follow you to the desktop MADE FOR ONE HAND • Slide between your lists, tasks and a utility panel with Tags, Nearby and Calendar Events; one thumb runs all three • Pinch to zoom between three levels of detail • Quick Open: type a few letters, land on any task or list • Batch edit and drag & drop: defer, tag or move a whole stack of tasks in one go YOURS, PRIVATELY • Lock individual lists or the whole app • Automatic backups, with single-list restore for the day something goes wrong • Share lists over Wi-Fi with other 2Do users nearby, no cloud in between • Independent light and dark themes • Apple Watch app with complications 2Do has been refined over years of careful work, with feedback from students, parents, professionals and lifelong list-keepers along the way. Use it as a simple list, or push it into full GTD® territory. Either way, it's ready.

Add up to 5 daily tasks by tapping the blue plus, then tap to complete or swipe left for 5-minute reminders. Each new day automatically gives you a fresh, clean slate to focus on what matters most. While other task apps overwhelm you with endless features and infinite task lists, Simple5 embraces the power of constraints. You're limited to just 5 tasks per day - not as a restriction, but as liberation from digital clutter and decision paralysis. This isn't random - it's based on cognitive science showing our brains can effectively prioritize maximum 5 items at once. When you can only choose 5 things, you automatically choose the RIGHT 5 things. When adding your tasks, you naturally consider the most important things you want to do. The app relies on that. Furthermore, you cannot delete your tasks once they have been written down. This is because it is not possible to "delete" something that has been written down with pen and paper. Choose how you want to spend your time wisely! Add up to 5 daily tasks by tapping the blue plus, then tap to complete or swipe left for 5-minute reminders. Each new day automatically gives you a fresh, clean slate to focus on what matters most. Key Features: * 5-task daily limit forces real prioritization * Automatic priority numbering (1-5) * Daily reset - no overwhelming backlog * Tap to complete, swipe for reminders * Built-in tutorial for instant understanding * Share your daily list as simple text * Clean, distraction-free design Why should I spend money: * No Subscriptions - Pay once, own forever * No Ads - Completely clean experience * Privacy First - Your tasks stay on your device * Thoughtful Design - Every detail carefully crafted * Quality Focus - Built for effectiveness, not feature bloat
