Our Applications

Everything YingZhiChu ships today

We publish four applications: three for iPhone, iPad and Android, one for macOS. None of them asks for an account, and each keeps your data in local storage on the device rather than on our servers. Where an application offers an upgrade it adds capability without gating the core function, as a one-time purchase or a clearly priced subscription.
