## Description

Measure length, width and angles with a touch. Calibrate with a real ruler or card for accuracy on any device. Works offline and is ready in an instant.

Simple Ruler is a practical measuring tool that turns your smartphone's screen into a ruler and protractor.

Whenever you want to quickly measure something — in daily life, DIY, or crafts — you can start measuring right away, with no complicated steps.

[Measuring Modes]
- Simple mode: Just touch the screen to instantly see the distance from zero to that point.
- Single-cursor mode: Slide one cursor to measure length precisely from the edge of an object.
- Dual-cursor mode: Move two cursors freely and measure the width (gap) between them with precision.
- Width x height mode: Measure vertically and horizontally at the same time and get an object's size (H x W) at a glance.
- Protractor mode: Move two lines to measure tilts and angles.

[Calibration for Accurate Measurement]
Screen pixel density varies from device to device. To display an accurate scale, this app offers two calibration methods:
- Using a real ruler: Hold a ruler against the screen and adjust the slider until the marks line up.
- Using a card: Calibrate with a standard-sized card such as a credit card — no ruler needed.
Once calibrated, your device works as an accurate ruler optimized for your screen.

[Designed for Ease of Use]
- Dark mode support: The app follows your device settings with an easy-to-read theme.
- Works offline: No internet connection required. Launch and measure anywhere.
- Privacy friendly: No access to your camera, location, contacts, or other personal data.

[Multilingual]
Available in English, Japanese, Korean, Chinese, Spanish, and many more languages.

Make everyday measuring smarter.
