### 4/5 — Great app, but needs Chinese TTS support

*2026-05-07*

The app is great, but the Text-to-Speech (TTS) on the Apple Watch seems hardcoded to English. It fails to read Chinese responses. Please add dynamic language detection for TTS or a language toggle in the settings. Will rate 5 stars once fixed!
