A dual-mode Chinese/English Input Method Editor (IME) for Android that lets you write Chinese and English concurrently without switching keyboards.
Traditional IMEs force you to switch between Chinese and English modes. DualQuickIME eliminates this friction:
Type "我love你" in one fluid motion - no mode switching, no interruption.
The keyboard intelligently understands your intent and commits Chinese or English based on your actions, making bilingual typing as natural as thinking in two languages.

- Context-aware commitment - tap for Chinese, type 3rd letter or Enter for English
