## What is Ideal Calendar?

A calendar that opens on one number: how many hours of today are still yours.

A calendar tells you which hours are taken. What you actually want to know is the opposite.


■ Your free time, on the home screen

Take the hours you're awake. Subtract what's ahead of you.

"Bed at 11. It's 7 now. One hour booked at 9."
— three hours left.

That number is the first thing you see when you open the app. Add an event and it drops, right there.


■ No manual

Long-press to add an event.
Drag to move it.
Swipe to delete it.

Every year you've spent with a phone is the only instruction manual you need.

"It probably works like this…"
— and your instinct is always right.


■ What that time is being traded for

Add a shift and your pay is worked out from your hourly rate, including night, overtime and holiday premiums. You can see what your free time turned into.


■ Also

• One tap between month and week view
• Drag across the week view to create; drag an event to move it
• Colour-code your events and read the month at a glance
• Attach photos to events and look back on them
• A lock-screen widget for today's free time
• Your events, tasks and photos stay on your device. No account required


Build your day, your way.

## Version history (last 5 releases)

### 2.11.1 — 2026-08-21

■ New

• Shared calendars now have their own Shared tab at the bottom of the screen
• You can see who has joined a shared calendar

■ Changed
• The week view gives more room to the hours of the day (the all-day row under the dates and the per-day free-time figure are gone)

### 2.11.0 — 2026-08-19

■ Fixed
• Reminders could fail to arrive even after you had set one
• Adding an event could start you on a time that had already passed
• Dragging an event to a new time left its reminder at the old one

■ Changed
• Reminders now say what time the event starts
• Only the duration you picked is highlighted

• Pay thresholds updated to the ones a student actually hits

■ Fixed
• Picking a date while on the last day of a month could land a month later
• The week view now starts its week on the same day as everything else
• Multi-day all-day events showed only on their first day in the week view
