Our self-developed focus-training Mini Program "Schulte Grid" is officially live. Based on the classic Schulte Grid method, it offers standard 5x5, advanced 6x6, and variant modes like letters and classical poetry.
The design principle is "light": no download, no registration, scan and train; millisecond timing with daily check-ins and friend rankings.
This is our first attempt at moving from "taking projects" to "building products" — iteration continues.
