Tilt Meter, Angle Finder
Only for iPhone

iPhone
Turn your iPhone into a precision spirit level. Set it flat on any surface and the bubble tells you instantly whether that shelf, picture frame, table or floor is truly level — no plastic tool required.
Most phone levels stop at a single bubble. BubbleLevel is built for real projects: a 2D bullseye and single-axis vial, a pass/fail surface checker with an adjustable tolerance, a full angle finder that reads in degrees or percentage grade, and a saved log so you can prove every reading later. Calibrate out a bent case or an uneven worktop once, and every measurement stays true.
WHAT YOU GET
- A live bubble level with a 2D bullseye and single-axis vial for shelves, frames and floors
- Real-time pitch and roll tilt readout so you can see exactly how far off level you are
- Surface check that gives a clear PASS or FAIL against a tolerance you set
- Angle finder and protractor reading degrees, percentage grade and roof pitch (rise-in-12)
- Slope reference for floor drainage, gutter fall, accessible ramps, stair stringers, roof pitches and plumb walls
- Learn section explaining level, plumb, the vial, grade and slope, and roof pitch
- Saved readings with timestamps so you can compare before-and-after or keep a record
- One-tap calibration that corrects a bent case or an uneven table for good, with a reset when you need it
- Lock the current reading so the value holds while you move the phone away
- Optional daily reminder to check your next job
PERFECT FOR
- DIY homeowners hanging shelves, art and mirrors dead straight
- Joiners and builders checking level, plumb and grade on site
- Renovators levelling floors, worktops and appliances
- Anyone who wants a true reading without carrying a bulky spirit level
WHY NOT JUST USE A PLASTIC LEVEL
A hardware-shop level only tells you level or not — it cannot measure the exact angle, log the result or fit in your pocket. BubbleLevel gives you the precise degree, a pass/fail verdict and a saved history, all on the phone you already carry.
PRIVACY
Everything runs on your device. No account, no cloud, no tracking — your measurements never leave your phone, and the app works fully offline.
FULL ACCESS
The live bubble level is free to use. BubbleLevel Premium unlocks the surface checker, the angle finder and your saved-reading history. Choose the plan that fits: Weekly, Yearly, or a one-time Lifetime purchase. Subscriptions auto-renew until cancelled; manage or cancel anytime in your App Store account settings.
Level your next project the right way — download BubbleLevel and get a straight, true reading in seconds.
