Chinese Learning for wawayaya Joyreader app ✅

I saw this wawayaya Joyreader app on the Lazada platform. Would be worthwhile to buy it for children? But my parents say reading is necessary, its worth, one of my friend intro me said it is good to use, her child will self-study because it is able to find the child's reading record and improve Chinese. The description mentions, able to reading, recording and pronunciation tests more intelligent by using sound technical support. Also, come with edictionary can select Chinese or English explanation. About the price is once a year, and every month increase the storybook. Still considering. . . >
