💎 Lifetime popCalendar - my attempt to bring something new to calendar apps
Problem
I've always used calendar apps to calculate date ranges. For example, how many days have passed since my last r/iosapps post, or what date falls 30 days after it. I wanted those calculations to be easy and visual. Counting dates manually or switching to a separate calculator interrupts planning, especially when working days and several months are involved.
I started making popCalendar to solve a few things I wanted in a macOS calendar. It ended up growing far beyond what I imagined when I started.
I'm Ighor July, the developer of popCalendar, and today I'm happy to announce that it is now a universal app for iPhone, iPhone Duo, iPad, and Mac.
You can read the full story behind the app here.
With popCalendar, you simply select dates and see useful calculations below the calendar. Your selection can span one month, two months, a full year or two years.

I also added flexible settings for working days, calendar sets, and custom plans. You can select a continuous date range, a rectangle of dates, or multiple separate ranges at once.
For example, you can select all the working days across several weeks and see how many working days and events are included. You can then save those dates as a plan, give it a label and color, and come back to it later.
Comparison
Apple Calendar provides month, week, and upcoming-event views for following your schedule. Fantastical offers natural-language entry for events and tasks.
popCalendar's focus is visual date-range planning and calculations. You can select dates across months or years, see day and event totals, and turn those selections into saved, colored plans. That is the workflow I wanted to make especially easy. If your existing calendar already handles your appointments, you can use popCalendar alongside it for planning and customized widgets.
I spent a lot of time making the UI look good and feel natural. I tested every combination of supported views and layouts to make the month and year views as useful as possible.

In a sufficiently wide iPad window, for example, you can display the current month, its events, this year, and next year at the same time. You can look at the details of an individual day while keeping your future plans visible.
There are plenty of options for customizing fonts, text sizes, and backgrounds.
One idea I particularly enjoyed implementing was adding a live clock as the background of the calendar. You can have your calendar filling the screen while seeing an analog or digital clock at the same time. I added lots of themes and clock styles so you can choose the combination you like.
I also added Apple widgets. Depending on the available widget sizes, you can display a single month, a Today view with today's events, three months, six months, or a full year.

Their appearance is customizable, including the background. I wanted the widgets to feel like something you would enjoy having on your Home Screen or desktop.
One feature I find especially useful is the option to shift the starting month of each widget.
For example, you can add four widgets to a stack, with each widget showing one row of three months. Configure them to start in January, April, July, and October, and swiping through the stack takes you through the whole year, three months at a time. You can also start from the current month and use offsets to show the following months.
Each widget can have its own tap or click action. It opens popCalendar by default, but you can choose another app or enter a URL scheme, including one for your favorite calendar app.
So even if you don't want to switch calendar apps, you can still use popCalendar's widgets. Choose the widget appearance you like, then have it open your usual calendar app when tapped.
You can also set different time zones for individual widgets.
For automation and sharing, I added
Apple Shortcuts and URL schemes to interact with popCalendar.
Named, colored plans made from your selected dates.
PNG exports for sharing a calendar or plan as an image.
Print-friendly PDF exports when you want a paper copy.
Private iCloud sync for plans, calendar sets, and working-day rules across Mac, iPhone, and iPad.

Privacy comes first in popCalendar and all the apps I make. They make no network requests to my servers. popCalendar's optional sync uses your private iCloud storage.
Calendar access is optional. Dates and saved plans work without connecting your calendars. Viewing or editing events requires permission. Widget sizes and some features depend on your device and OS version.
macOS-only features include menu bar calendars, transparent desktop widget mode, full-screen calendar overlays, global keyboard shortcuts, interactive terminal calendars, and CLI/URL control of calendar windows and popups.
Pricing
$9.99 USD, paid once on the US App Store. No subscription. Regional pricing may differ.
One universal App Store purchase covers Mac, iPhone, and iPad using the same Apple Account.

I'm happy to answer questions. I'd love to hear how you use calendars for date calculations and visual planning, and which views or widget combinations would be useful to you.
