## What is 321 GO?

Know when to arrive. See when to start.

321 GO works backward from your arrival time to turn preparation, tasks and travel into a clear, step-by-step plan. Know when to get ready, when to leave and what to do next, then follow your progress as you go.

PLAN BACKWARD
Choose the full arrival date and time, add a buffer and arrange steps in the order you will do them. Change durations or reorder your steps and your preparation and departure times update together. Travel times are your own estimates, with no location tracking or live traffic lookup.

GO FORWARD, ONE STEP AT A TIME
Start your journey and focus on the current step's countdown. Confirm completion to move on, add five minutes when you need more time, or pause, resume and skip steps. Your arrival deadline stays fixed so you can see how much room remains. An expired timer never assumes you have finished the task.

FOLLOW ALONG FROM YOUR LOCK SCREEN
Live Activities show the current step, countdown, next step and progress. Confirm completion or add time from the lock screen. On supported iPhones, the Dynamic Island also keeps your journey timer in view. Home Screen widgets show your next plan or current journey.

START WITH A FAMILIAR ROUTINE
Use morning, airport, meeting and focus templates, then make the steps your own. Add symbols, notes and web links. The interface supports English, Simplified Chinese and Dark Mode.

PLAN FOR FREE. KEEP YOUR ROUTINES WITH PRO.
Create and track journeys, use built-in templates and follow Live Activities for free. Pro lets you save custom templates, review past journeys and reuse your plans. One-time purchase, no subscription.

Your journeys stay on your device. Reminders are optional. Task and travel durations are estimates you enter; always check important departure and arrival details yourself. Live Activity availability depends on your device and system settings.
