About this app

Turn your Android phone into a precise, professional-grade spirit level — with smart tools that go far beyond a simple bubble.

REAL-TIME BUBBLE LEVEL
- Dual-axis bubble with colour-coded feedback (green = level, amber = close, red = off)
- Pitch and roll shown together in large, clear digits
- 4 unit modes: Degrees, Grade (%), Inches per foot, and Millimetres per metre — tap to switch
- Hold Mode freezes the reading while you reposition
- Calibrate to zero on any reference surface, or reset to factory defaults anytime
- 3 surface modes: Horizontal, Vertical (plumb), and Slope (custom target angle)
- Adjustable level threshold from ultra-precise to construction grade
- Haptic and audio feedback the moment your device hits level

AR CAMERA OVERLAY
Point your camera at any wall, shelf, or surface and see the level overlaid in real time — with a horizon line that rotates with roll and a live level-status banner. Perfect for hands-free levelling while hanging pictures, fitting tiles, or installing shelves.

TWO-POINT ANGLE CALCULATOR
Capture a reading from Surface A, then Surface B, and instantly get the angle between them. The app tells you whether surfaces are parallel, square, at a standard 45° mitre, or how much adjustment is needed — ideal for corners, roof pitches, and stair treads.

MEASUREMENT HISTORY WITH PHOTOS
Save any reading with a name, notes, and an optional photo. Everything is stored on your device and shown in a clean list with thumbnails, level-status indicators, and all units at a glance.

CONTRACTOR PDF REPORTS
Generate a professional PDF of your saved measurements in seconds — complete with job details, a full measurement table, photo thumbnails, level/off-level status, and summary statistics. Share to email, messaging, cloud storage, or print to document work for clients.

SMOOTHER, SMARTER READINGS
Spirit Level fuses the gyroscope and accelerometer with a Kalman filter for noticeably steadier, faster, more accurate readings — even on vibrating surfaces or during slow movement.

EXPORT OPTIONS
- CSV export for a spreadsheet-ready file of all measurements
- PDF export for a polished report with photos and stats
- Both share through Android's standard share sheet

PERFECT FOR
Builders, carpenters, tilers, plumbers, electricians, interior designers, DIY home improvement, art and photo hanging, furniture assembly, and kitchen or bathroom fitting.

PRIVACY FIRST
All measurements and photos stay entirely on your device. No account. No cloud sync. Nothing leaves your phone without your explicit action.
