## What is 量尺 Ruler?

Turn your phone screen into a real ruler — open it and start measuring.

• No calibration: your device model is matched automatically
• Four units side by side: cm, mm, inch, and cun
• Input positioning: type a length and the ruler jumps to it
• Draw to measure: draw any line and read its length instantly
• Mini games: match-the-length and guess-the-length, solo or with friends
• Two themes: hand-drawn and geek
