心算口算(FULL) app for iPhone and iPad

Why I make this app?
This app is for my daughter Qiqi.
Tried many applications about quick calculation, I find no one can meet my needs. Some which set questions automatically always set fool questions, especially when they meet 3 numbers mixed calculations. Some which have a fixed question bank always repeat questions over and over. These all aren’t what I want.
Moreover, I think setting questions free is necessary, setting individual questions for kids at different study levels. Yes, some apps have this function, but it’s too inflexible for users. I need more free.
Lastly, the price of the APP. It’s unreasonable to separate questions of every term to make more money, because there is less difference, such as, between grate 2-1 and grate 2-2.
So, I do it myself.

Why to practice quick calculation?
Let me make an example. There are two ways to improve the efficiency of computers processing tasks. One is writing programs to optimization algorithm, to use existing CPU computing power as much as possible. The other one is improving CPU computing power, to speed up processing all tasks.
A brain is like a CPU, and learning knowledge is like a computer processing a variety of tasks. In order to improve study, we can master different learning methods for different subjects. Or, simply, speed up our brains by practicing quick calculation in the initial stage of study. The more quickly our brains work, the more quickly we learn, even learning more quickly than others on learning different methods for different subjects.

Why choose to use this APP?
1. I put my whole heart into this app for my daughter. I believe I have tried my best to taken every detail into account, and choose the optimal design in the program.
2. It’s the best time for kids to practice quick calculation from 5 to 8 years old. With the great help of several professional primary school math teachers, based on the newest Primary School Mathematics Curriculum Standard, I set recommended combinations for kids in this age. One-touch to select question forms, it’s so convenient and practical.
3. There are no two kids exactly same in the world. Setting questions totally free, which makes every parents can select individual question forms for their kids, and save as their own combinations.
4. The best answer interface, keyboarding + auto-scrolling, the least touch bring the maximum efficiency when answering. PS: The hand-writing mode isn’t conducive to develop good writing habits for kids, so I promise the hand-writing mode will not be provided forever.
5. Query records is continent to parents and kids to view their study. Records summary shows the changes of kids’ quick calculation abilities visually. Insist on the use of quick calculation for a long time, you will see kids’ progress from graphs.
6. Single purchase, remove ads and all functions opening.
