## What is Slope Level RX?

Slope Level turns your iPhone into a clear and practical slope meter for everyday measuring tasks.
Use it to check surfaces, shelves, frames, tripods, vehicle parking angles, camping ground, and other non-certified measurement needs. The main screen opens directly to live readings, so you can measure without menus or setup.
Key features:
• Real-time slope and tilt measurement
• Plane mode for flat surfaces
• Edge mode for one-axis angle checks
• Zero calibration for relative measurement
• Hold current reading
• Save local measurement history
• Switch between degrees, percent grade, and slope ratio
• Light and dark appearance with configurable theme colors
• Works offline and does not require an account
Slope Level is designed for quick reference and everyday utility. It is not a certified industrial measuring instrument and should not be used for safety-critical or regulated engineering measurements.
