## What is AI Calendar Planner?

ProntoCal is the simple, powerful all-in-one AI calendar, to-do list, planner and reminders app for iPhone, iPad and Mac. Type a plan the way you'd say it, and AI fills in the time and place.
Entering plans by hand is a chore, so you forget. ProntoCal fixes that: events and to-dos on one screen, overdue to-dos in red with a reminder, your day on a map, and notes, links and photos attached to any plan.

SOUND FAMILIAR?
- Setting the date and time for every event is tedious, so you put it off
- Your calendar and your to-do list live in different apps, and things slip through
- You look up the same place on the map every time
- You want the shopping list or the transit screenshot right next to the plan

WHAT YOU CAN DO WITH PRONTOCAL
- AI quick add: type "Lunch at Ferry Building tomorrow 1pm" and it goes on the calendar for tomorrow at 1pm with the place filled in
- See events and to-dos on one screen: today's list sits under the month view. Swipe up for the week
- Never lose an overdue to-do: it stays red until it's done, and reminds you
- See your day on a map, in order
- Attach notes, links and photos to any event or to-do
- Check off to-dos right from the Home Screen widget
- Sync across iPhone, iPad and Mac, in light or dark mode

PERFECT FOR
- Anyone who forgets plans because entering them feels like a chore
- People who don't want to switch between a calendar and a to-do app
- Keeping reminders on the calendar without a separate reminders app
- Keeping photos and notes with your plans

Never "oh no, I forgot" again. ProntoCal remembers for you and lets you know.
