## What is Calendar Planner?

ProntoCal helps you capture everything you need to do today—events and to-dos—so nothing slips through the cracks. Your day sits next to a weekly calendar, making it easy to scan the week at a glance. And with a simple swipe, you can switch between the weekly and monthly calendars to see the bigger picture. Plus, with seamless sync across iPhone, iPad, and Mac, your schedule is always up to date no matter which device you use.

Feel any of these pain points?

* You want reminders to appear on your calendar.
* You’d like to save to-dos with photos.
* Using separate apps for calendar and to-dos scatters information and leads to forgetfulness.
* Switching between month and week views is a hassle.
* Entering the exact date and time for every event is tedious, so you put it off.
* You wish your events and to-dos synced instantly across iPhone, iPad, and Mac without extra effort.

With ProntoCal, it’s all in one place:

* Notifications that actually remind you: log it here and the app will nudge you when it’s time.
* Events and to-dos on one screen: see your day, week, and month together. Swipe up on the month view to switch instantly to the week view.
* Widgets: check today’s schedule and your to-do list at a glance. Mark tasks done right from the widget—no need to open the app.
* AI-assisted entry for title and date/time: type phrases like “Tomorrow 1 pm cafe” or “Report due next Friday,” and the AI parses and fills in the details for you.
* Photo attachments: pin screenshots or photos directly to events and to-dos. Add a transit screenshot to a meeting, attach a flyer to a shopping list—save anything you want to remember as an image.
* **Seamless sync across devices:** whether on iPhone, iPad, or Mac, your events and to-dos stay perfectly aligned. Plan on one device, continue effortlessly on another.

Perfect if you:

* Often forget what you need to do
* Want to see reminders right on your calendar
* Don’t want to waste time switching between calendar and to-do apps
* Prefer checking and completing tasks from widgets
* Find event entry a chore and end up missing important plans
* Want smart, stress-free schedule management even on busy days
* Like adding photos to events and to-dos
* Need your tasks and schedules synced reliably across all Apple devices
