About

Ideal Calendar

Features
Read full description

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.
