This is a brain training game in which you calculate the time difference between two analog clocks.
See how many times you can get the right answer within the one-minute time limit.
You can set the minute hand of each clock to move in 1, 5, 10, 15, 30, or 60 minute increments, so even people who have difficulty seeing the fine details of a clock or who are not good at precise calculations can enjoy it.
You can also change the clock display to a dark theme.
Press the menu button in the top right of the screen to set the minute increments and dark theme.
Your best score will be saved for each time setting.
