LevelScope app icon

A level, inclinometer, plumb and compass in your pocket.

LevelScope turns your Android phone into a set of measuring tools, and keeps a record of what you measure. It works fully offline, with no account and no ads.

Six tools

Everything you need to check an angle

Each tool reads the phone’s motion sensors, smooths the reading and tells you when it is stable.

  • Bubble level

    Level a surface on two axes with the phone lying flat.

  • Bar level

    Stand the phone on any of its four edges and level along a line.

  • Inclinometer

    Read an angle in degrees, percent slope, or as a 1:X or X:12 ratio.

  • Plumb

    Check that a wall, post or frame is vertical.

  • Compass

    Magnetic heading and cardinal point, with a warning when something interferes.

  • Relative angle

    Set one surface as the reference and measure another against it.

Compass: heading, field strength and sensor accuracy.

More than a reading

Measure once, keep it

  • HOLD

    Freezes the average of a steady stretch of readings, not just the last one, and shows how much it varied.

  • ZERO and targets

    Set the current position as zero, or pick a target angle and get a vibration and a beep when you reach it.

  • Calibration

    A guided two-step calibration, with separate profiles for a case, no case, or each edge of the phone.

  • Projects and history

    Save measurements with a name, notes and project. Search, filter and compare them later.

  • Export

    Share your measurements as CSV for a spreadsheet, or as a complete JSON file.

  • Light and dark

    Follows your phone’s theme and language.

Privacy

Your measurements stay on your phone

LevelScope does not collect anything, because it cannot: the app does not even have permission to use the Internet.

  • Fully offline

    Every tool works with no connection.

  • No account

    Nothing to sign up for.

  • No ads or trackers

    No analytics of any kind.

  • No cloud copy

    Data leaves the phone only when you export a file yourself.

Not a certified instrument. Accuracy depends on your phone’s sensors, the calibration and how the phone rests on the surface. The readout can show hundredths of a degree; that is its resolution, not a guarantee of accuracy. Do not rely on it where an error would matter for safety.
