【What is SoroTouch?】 Equip your child with mental calculation abilities that last a lifetime. Become a math pro with our world-standard ”two-handed system"! SoroTouch is an EdTech app designed to help children master abacus-style mental calculation by visualizing numbers as "bead images" through patented technology. We especially recommend it for children aged 5 to 8, a period of high brain plasticity. With just 30 minutes of daily practice, children aim to become mental calculation masters (handling problems like 2digits 8numbers addition and subtraction) within two years. *This app is exclusively for SoroTouch members. *A User ID and password are required for access. 【Features】 ・Just 30 Minutes a Day!: Consistent daily practice builds lifelong calculation skills. ・Fun, Game-like Learning!: Featuring over 20 types of games to support learning. Children learn fast and accurate touching while having fun. ・Patented Mental Calculation Board: Using our patented board based on abacus principles, children can start mental calculation training from day one. This is a new learning method to efficiently master "image-based mental calculation.” ・Global & Online: Compete and learn with children worldwide through "Rankings" and "SoroFes." By experiencing diversity, children learn to respect one another. ・Continuous Updates via Data Analysis: We analyze daily learning data to constantly improve and update the app. 【FAQ】 Q: Can I use the app immediately after installation? A: This app is for SoroTouch members only. Please note that prior membership registration and a valid User ID/password are required. Q: Why is my answer marked "incorrect" even if the number is right? A: SoroTouch focuses not only on the "answer" but also on "correct finger movements." Mastering the right touch ensures "authentic mental calculation abilities" that work even as numbers and digits increase. Please check the instructional videos for the "correct finger movements" first. Q: What should I do if the beads don't respond well to touch? A: You can adjust the bead size from Settings>Board to match your child's hand size. Also, the secret is to touch firmly with the pads of the fingers rather than using fingernails.
