Mobile vs. Web Features
PrimeCal's mobile app and web app share the same codebase and data. Almost everything you can do on the web, you can do on mobile. The main differences are in how things are presented and navigated.

Navigation Differences
Web: Left sidebar always visible with calendar list and groups. Top navigation bar with view switcher.
Mobile: Left sidebar becomes a slide-out drawer (tap the hamburger menu). Bottom tab bar replaces the top navigation for primary actions.
Month View on Mobile
On mobile, Month view shows up to three event dots below each day number instead of full event cards, and the grid is compact enough to leave room under it. Tap any day and its events are listed right there, under the grid: no sheet opens over it, so the dots and what they stand for stay on screen together while you go from day to day. Tap an event for its card, or Add to start Quick add on that day. Week numbers, if you have them on, are there too.
Day and 3-Day Views on Mobile
A week of columns is too narrow for a phone, so Day and 3 days are the time-grid views (a link to Week opens as 3 days). They are the same scrollable 24-hour grid as on the web. Tap a time slot to start creating an event at that time.
Creating Events on Mobile
- Tap a day in Month view and then Add, under the grid, to quick-add an event on that day
- Tap a time slot in the Day or 3-day view to create at that exact time
- Tap the floating "+" button and then Quick add, the entry nearest the button: type the event as a sentence ("Dentist friday 3pm"). The same list has New event for the full editor, New task and Start a routine. Where there is nothing but events to create, the button opens Quick add at once
Swipe Gestures
- Swipe left: go forward in time (next week/month)
- Swipe right: go back in time (previous week/month)
- Pull down from the very top of a view: refresh calendar data (scrolling a day back up does not refresh)
Moving Events on Mobile
- Press and hold an event, then drag: rest your finger on an event for about a third of a second, then drag it to another time or day and lift. The grid scrolls by itself when you carry it to the top or bottom edge
- Pull the bottom edge: change how long an event lasts
- A swipe that starts on an event still scrolls, and dropping an event on another day does not page the calendar
What Works Better on Desktop
- Fine drag and resize: moving and resizing work with a finger, but a mouse is more precise for quarter-hour adjustments
- Multi-column week view: ultra-wide screens show more days at once for a better weekly overview
- Detailed admin panels: the Admin panel and Subscription settings are designed for desktop use
For scheduling-heavy work like Will's deep work time blocks, the web app's drag-and-drop in Week view is faster. For checking May's family schedule on the go, the mobile app is perfect.
