Buru Arithmetic vs 口算之王

[Description] "Buru's Arithmetic" is different from traditional oral arithmetic apps. Once the app is started, it will adjust itself smartly according to the child's proficiency level, without the need of a parent's configuration. By empasizing on proficiency, the app constantly pushes the kids to solve problems faster while answering correctly. In our study, after two weeks of training, the kids practising 20 minutes daily were able to reach high proficiency of oral arithmetic with adding and subtracting numbers within 100. [Key Features of Buru's Arithmetic] 1. Quick detection of the child's arithmetic proficiency level and automatic adjustment of problem difficulty. 2. Focus on improving solving speed while ensuring answers correctness. 3. Repetitive pratice of mistaken problems to improve correction efficiency. 4. Progress Tracking dashboard for parents to check the kids' learning record and improvement at a glance. 5. Supports multiple accounts, so kids can share the same device for training, and each account tracks progress independently. 6. Say goodbye to the old and boring arithmetic exercises, instead come fight against cute monsters in this fun game as a way to sharpen your arithmetic skills.
