Level Measure Pro

Level Measure Pro turns your phone into a bubble level and tilt meter. It shows the angle, and in Edge mode it also tells you what to fix, for example "Raise left side 4 mm".

EDGE MODE
Stand the phone on its edge on a shelf, picture frame or worktop.
• Angle dial with a moving needle, plus a bubble vial
• Correction hint in millimetres, based on a frame width you set
• The display turns so the text stays upright on whichever edge is down

FLAT MODE
Lay the phone screen up on a table, floor or appliance.
• Bubble target with X and Y bars
• Shows which side is high
• Total tilt plus separate X and Y readings

Auto switches between Edge and Flat as you move the phone. Tap a mode to keep it, or tap Auto to switch back.

UNITS AND TECHNICAL DATA
Switch the main reading between degrees, percent, millimetres per metre and ratio (1:X). The technical data panel shows angle, slope, ratio, rise, the rise over your frame width, and the calibration offset in use.

HOLD AND SAVE
• Hold freezes a smoothed reading so you can read it after lifting the phone
• A held reading shows slope, rise, ratio and the correction needed over your frame width
• Save readings with a name and review them later
• Swipe to delete a saved reading
• Saved readings stay on your device

CALIBRATION
A phone's sensor and case are rarely perfectly true, so calibrate before careful work.
• Two-point calibration: capture a reading, turn the phone 180° on the same spot, capture again
• Separate calibration for Flat mode and for each edge
• "Set zero here" makes readings relative to any surface you choose
• Reset to factory values at any time

FEEDBACK AND SETTINGS
• Haptic feedback when the reading reaches level (on devices with haptics)
• Optional light tick for each degree above 1°
• Screen reader announcement when the reading reaches level
• Level tolerance: 0.1°, 0.25°, 0.5° or 1.0°
• Smoothing: Fast, Normal or Steady
• Default units and frame width
• Keep the screen awake while measuring
• English and Urdu

GOOD TO KNOW
Phone levels are for guidance. For structural work, check with a dedicated measuring instrument. A phone is only about 15 cm long, so for floors and other long surfaces, place it on a 1–2 m straight edge.
