Bubble Level

Features
Read full description

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 percent grade, and a saved log so you can prove every reading later. Calibrate out a bent case or an uneven counter 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 - Surface check that gives a clear PASS or FAIL against a tolerance you set - Angle finder and protractor reading degrees, percent grade, and roof pitch (rise-in-12) - Slope reference for drainage, gutters, ADA ramps, stair stringers, and roof pitches - Saved readings with timestamps so you can compare before-and-after or send proof - One-tap calibration that corrects a bent case or an uneven table for good PERFECT FOR - DIY homeowners hanging shelves, art, and mirrors dead straight - Carpenters and contractors checking level, plumb, and grade on site - Renovators leveling floors, counters, and appliances - Anyone who wants a true reading without carrying a bulky spirit level WHY NOT JUST USE A PLASTIC LEVEL A hardware-store 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.
