Transferidor BLA vs Bubble Level

Measures any angle. The iPhone becomes a protractor. You rest it against a surface, a wall, a ramp, and read the large angle in BLA typography. Tap to calibrate, hold mode to freeze the reading. The free protractors on the App Store are throwaway utilities, full of ads, with garish icons. Transferidor BLA is the opposite. Editorial typography, Areia BLA background, large angle display in whole degrees, arc with fine marks every 5 degrees and long marks every 15. WHAT IT'S FOR When the problem is the tilt: the accessibility ramp at the store (code says at most 8.33%), the TV that needs to hang straight on the wall, the small solar panel that wants about 16 degrees in Goiânia, the picture frame to be cut at 45, the wobbly table leg. The protractor from your school ruler now fits in your pocket. And it shows you with calm. ARC AND POINTER Semicircle arc with fine marks every 5 degrees, long marks every 15, numbers 15, 30, 45, 60, 75 and 90 on both sides of zero at the top. Pointer animated with soft physics, no jitter on quick moves. Large angle display in whole degrees, in serif Tinta. NOTABLE ANGLES When the angle hits a value that matters to the craft (zero, one third, half, two thirds, plumb), the app highlights quietly with a Verde BLA capsule. No fanfare. Just an editorial confirmation. CALIBRATION The reading comes from the accelerometer and gyroscope of the iPhone, with magnetic correction so it doesn't drift when you rotate the device. You place the iPhone on what you consider zero (the surface that should be level, the wall that should be plumb), tap calibrate, and the app reads the tilt relative to that zero. Works the same in portrait, in landscape, in any rest. Tap recalibrate to change the reference, tap clear calibration in Settings to go back to the raw reading. HOLD MODE Tap hold to freeze the reading on the display. Useful for measuring in tight spots (under a piece of furniture, behind a TV, in an awkward angle) and reading it later. Tap release to resume. 2 THEMES Areia BLA, light background with the brand base. Tinta, dark mode for low-light environments. The theme follows the iPhone's Dark Mode. 100% OFFLINE No data collection. No network. No login. No analytics. No crash reports. One-time purchase, open, measure. Transferidor BLA is an app made in Goiânia by BLA Publicações e Conteúdo Digital, an independent editorial studio led by Ivan Grycuk.

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.
