How to play
Look at where the hands point and choose the time from three answers.
Difficulty
Whole hours only. Start with the hour hand and "what hour it is."
Press "Start" and a clock appears. Look at the hands and answer "What time is it?" by tapping one of three choices. 10 questions in all.
Reading a digital clock is just reading a number. An analog clock is different: two hands, two angles, and the child has to assemble "what hour, what minute" in their head. Clock Read practises that assembly from two directions.
"Read" shows the hands at a random time and asks "What time is it?" — pick the right answer from three choices. It trains the eye to notice where the hour hand sits and where the minute hand points. "Set" works the other way: drag the hour and minute hands until the clock matches a given time, then press "Check." Moving the hands yourself reveals things reading alone misses — for example, at 3:30 the hour hand sits exactly halfway between 3 and 4. Set mode is where that clicks.
The difficulty of a clock isn't about big numbers — it's about the layers of meaning the hands carry. The short hand tells the hour; the long hand tells the minutes. The first thing that trips children up is the simple fact that two hands carry two separate pieces of information.
In Set mode, press and drag anywhere on the clock face. Which hand gets grabbed depends on angle: the app measures the circular distance from your touch angle to each hand's angle and picks the nearer one. For example, if the hour hand is near 2 o'clock (about 60 degrees) and the minute hand near 6 (180 degrees), touching toward 3 o'clock grabs the hour hand while touching toward 5 grabs the minute hand. When both overlap, the hour hand wins. Once you start dragging, the browser's Pointer Capture keeps the hand following your finger even if it slides off the clock face.
When you're done, press "Check" and both hands snap to the nearest step for the current difficulty. If your positioning was roughly right, it counts as correct. The snapped position is the precise answer, so any gap is visible at a glance.
In Read mode, tapping the wrong choice greys it out so it can't be tapped again, but the correct answer is never revealed outright. The child picks again from the remaining options. This way, even if it takes elimination, the child arrives at the answer themselves — which sticks in memory far better than being shown the answer. Only questions answered correctly on the first try count toward the score, so the number reflects genuine "I knew it" moments rather than lucky retries.
Best scores are saved per combination of mode (Read / Set) and difficulty, and shown on the settings screen. Seeing "I got one more right than last time" gives a small, visible sign of progress — especially valuable for clock practice, where repetition is key. That visible improvement is often what makes a child choose "Play again" on their own.
"Wake up at 7," "dinner at 8," "a snack at 3" — recreating everyday times in Set mode turns the abstract "what hour, what minute" into something personal.
Parents can reinforce this outside the app by simply asking "Where's the long hand right now?" during the day. Clock Read is a practice ground; going back and forth between it and a real analog clock is where the learning deepens.
Clock Read runs entirely in your browser. The clock is drawn with SVG, times are read aloud by your device's built-in speech synthesis (Web Speech), and sound effects are synthesized on the fly with Web Audio. There are no external connections at all.
The only thing saved is your best score per mode (Read / Set) and difficulty, stored in your device's localStorage. No names or ages are entered, and nothing you answer is sent anywhere.
