AtomCalendar: Lucky Planner
GTD to-dos for happier days
Free · Designed for iPad. Not verified for macOS.
Planning apps keep getting complicated. AtomCalendar keeps it simple: capture a task, drop it into your calendar, check it off, with an AI companion cheering you on.
A simple GTD planner that makes every day feel a little luckier.
AtomCalendar is a GTD (Getting Things Done) to-do list and calendar, with an AI companion who plans and reviews your day with you. Capture anything in a second, give each task a clear next step, see how much you've completed, and move through your day at a pace that feels right. No complicated setup.
CAPTURE IT, THEN CLARIFY
• Drop any task, idea, or to-do into your inbox as it comes up
• Clarify each item with one tap: next action, waiting for, scheduled, someday/maybe, reference, or done
• Projects with checklists, so every project has a clear next action
• A guided weekly review walks you through six lists in about 20 minutes
YOUR DAYS AT A GLANCE
• Month and week views, plus a timeline for today
• Two-way sync with Google Calendar and the Calendar app on your iPhone or iPad
• View-only calendars by link (ICS), like holidays or team schedules
• Lunar calendar dates and the 24 solar terms, a calendar tradition everyone in Taiwan grows up with, shown for each day you open
NINE COMPANIONS BY YOUR SIDE
Nine illustrated AI companions, human and animal alike, plan and review your day with you, each in their own voice, and cheer on every small step: Rin, Fu, Haru, Lily, Uncle Yue, Yun, Mugi, Douhua, and Momo. Pick the one who feels most like you, and switch anytime.
LITTLE THINGS THAT MAKE IT FUN
• Free Atom Points every day, just for opening the app
• A flower of the day and its meaning, to set the tone
• Check things off and see your week come together in the weekly review
AN OPTIONAL DAILY SUGGESTION
• A short card on your Today screen looks at your actual tasks and events and suggests when to focus and when to take it easy
• Add birth details if you like, for extra notes from the Chinese almanac, BaZi, and Western astrology. Every task and calendar feature works without them
• Open an in-depth reading for any day or event with free Atom Points, whenever you're curious
PRIVATE BY DESIGN
• Sign in with Apple or Google, with no password to remember
• Your birth details are encrypted on our servers, never stored on your device
• No personalized ads. We never sell your personal data.
ONE ACCOUNT, EVERYWHERE
Free on iPhone and iPad, and on the web at app.atomcalendar.com, with one account.
Almanac, BaZi, and astrology readings are for cultural interest and enjoyment, not advice or predictions. The choices are always yours.
