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. β–  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." β€” three hours left. That number is the first thing you see when you open the app. Add an event and it drops, right there. β–  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…" β€” and your instinct is always right. β–  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. β–  Also β€’ One tap between month and week view β€’ Drag across the week view to create; drag an event to move it β€’ Colour-code your events and read the month at a glance β€’ Attach photos to events and look back on them β€’ A lock-screen widget for today's free time β€’ Your events, tasks and photos stay on your device. No account required Build your day, your way.
