How Yoyu works

Yoyu is a departure timer. It counts back from your target time and uses color to tell you when to leave. You set three things once, then you only open it each morning.

The three settings

Target time

When you need to arrive, or when something starts.

Travel time (min)

How long it usually takes you to get there. Your own everyday estimate is enough.

Extra time (min)

A buffer so you are not rushed at the last second. A bigger buffer means Yoyu tells you to leave earlier.

Time until yellow is different. It sets when the screen turns yellow as your remaining time runs low.

Reading the screen

The big number is the time left until your departure limit. After you pass it, the number shows how far over you are.

Departure limit = Target time - (Travel time + Extra time).

What is OFFSET?

OFFSET is your travel time plus your buffer. For example, travel 6 minutes plus buffer 2 minutes shows OFFSET +8m.

What the colors mean

Green: you have time to spare.

Yellow: your remaining time dropped below the yellow threshold.

Red: you are past your departure limit.

Red means you are past the leave-by time you set, including your buffer. If you are still within that buffer, you may still arrive on time. Set Extra time to 0 if you want red to mean truly late.

The idea

For a route you take every day, setting it once is enough. No maps, no traffic, and no account required.
