I really liked this app so i bought the 37$ version in the app, it didnt work at all but my money was gone. i was given a number, when i tried calling it, it was in Chinese and i dont speak that language so it didnt help with anything. i even wrote an email and been trying to contact them ever since august 2020 and i wrote a previous preview and it got deleted. i want my money back.

付费后用了两天后续再用就一直无法登陆了，也联系不上客服 请问是在割韭菜吗？😔

L1从大到小排序有问题 “From big to small” level is broken. It just doesn’t work at all. I’ve opened it on my iPhone and iPad. It’s just this level so far. But my son really enjoys this app and it doesn’t work. I’ve contacted the customer 4 times already. No response. The customer service is useless.

已经付了费用。可老是登录不进去。这个软件的登录系统有很大的bug。

We loved this game; it was our math-loving son's favorite math learning app. There have been a lot of changes to it over the years, including a cap on levels that allowed players to play only five per day at most. But the latest update has completely removed all English language from the game, and that makes it unplayable for us. We are sad to see it go, and will be uninstalling it.

还改得这么垃圾！我交钱买的不是这东西！

I het the is a Haidet game

We've happily paid for every feature. It's fun, engaging, and ad-free. It does suggest their own other products, of which I have paid for some. I wish it didn't though. It focuses on counting and is repetitive + simple enough for 2 and 3 year olds. It has one and two player mini games that we can all truly enjoy playing. The music is stellar. I believe it can be played in Chinese Mandarin as well. I'll be setting that up for my kids soon since they've learned the mandarin numbers. I only wish it could have accounts. I have two kids and would love to lock off the addition and subtraction worlds from the younger one who isn't ready for that and can click through it.
