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.
