KnowClock takes children aged 2-8 from reading a clock face to actually using time, across seven levels that build on each other. - Full Chinese voice guidance: kids can play on their own, no reading required - Age-based difficulty: whole hours for toddlers, half hours next, then five-minute precision and time math - Works fully offline. No ads, no third-party SDKs, no personal data collected - Every purchase and settings entry is behind a parent gate Seven levels 1. Recognise: learn the hour, minute and second hands 2. Listen: hear the time spoken, pick the right clock 3. Match: connect times to daily routines like breakfast and bedtime 4. Challenge: ten mixed questions scored by accuracy 5. Set the hands: drag both hands to the correct position 6. Find the time: read a description, pick the matching clock 7. Calculate: work out elapsed time and end times, bridging into primary school maths Time-sense training Six activities build an intuition for how long a minute really is: hourglass, one-minute challenge, beat challenge, time race, scene countdown and head-to-head duel. My Schedule A 24-hour ring shows the whole day at a glance, so children can see what comes next. Assessment and weekly reports Fifteen questions measure five skills, shown on a radar chart. Every week you get practice time and stars earned, ready to save and share. Printable worksheets Age-appropriate exercises you can print and practise on paper.
