## Description

Drag the hands to set the time. Get it wrong and the app shows you which
hand is off, then shows the answer. Free, with no in-app purchases.

Drag the hands with your finger and learn to read a clock.

The app asks for a time, such as "Set the clock to 7:30." You grab the hour
hand and the minute hand and move them. The time is set the moment you lift
your finger.

Getting it wrong does not end anything. The first miss tells you which hand
is off. The second miss moves the hands to the right place and shows you.

NINE KINDS OF QUESTION
Read       o'clock / half past / 5 min steps / 1 min steps
Calculate  minutes later / minutes earlier / time passed
Notation   AM and PM / 24-hour

They are arranged from easiest to hardest, but you can start anywhere.
Nothing is locked behind finishing something else.

ANALOG AND DIGITAL AT THE SAME TIME
Choose Clock, Digits, or Both. The digital display is a split-flap board,
the kind where the top half falls to reveal the next number. Pick Both and
the digits move as you move the hands, so "short hand between 7 and 8, long
hand on 9" and "7:45" become the same thing.

WHAT YOU CAN DO
- Drag the hands. The time is set when you lift your finger
- One-minute precision
- The hour rolls over when the minute hand passes 12, like a real clock
- A missed hand lights up in orange
- Switch between English and Japanese
- Turn the music and sound effects on or off
- Your display and language choices are remembered for next time

FREE, WITH NO IN-APP PURCHASES
Every question is free. There are no in-app purchases and no subscriptions,
and nothing is locked behind a paywall.

ABOUT THE ADS
A banner sits at the very bottom of the screen. It is kept clear of the clock
face and the Done button, and it never interrupts a question. Ad content is
limited to the general audience (G) rating.
