Bubble Level - Angle Finder turns your iPhone into a practical, accurate bubble level for everyday measuring, alignment, and leveling. Most phones do not sit perfectly flat. Cases, raised camera lens bumps, uneven backs, and different phone shapes can all affect level readings. This tool is designed with proper calibration so you can account for real-world phone surfaces and get more reliable measurements. Use it to check whether a surface is level, measure angles, align objects, or quickly verify slope. It is useful for hanging shelves, setting up furniture, aligning picture frames, checking tables, DIY projects, and quick household measurements. Features: - Bubble level for horizontal and vertical surfaces - Proper calibration for phones with cases and camera bumps - Helps account for uneven phone backs and raised lens areas - Angle and slope measurement - Clean, easy-to-read display - Fast launch for quick checks - Useful for home projects, DIY, furniture setup, construction, and alignment A phone level should work with the phone you actually use — case, camera bump, and all.

Read full description

Pipe Craftsmen is the pipefitter's toolbox: the numbers you work to, in the tape's own language, with every dimension copied from the published tables and every drawing showing where the number runs on the steel. THE SPOOL Build a spool piece by piece - pipe, fittings, valves, field welds - branching at a tee. Add an offset the way you measure it, run and offset, or a rolled one with its roll; the elbows go in by themselves, stock 45s or a 90 cut down to the odd angle. Lay an equal spread beside it. Read the drawing as an iso, a plan or any elevation, tap a pipe to put the ruler on it, and get the cut list: center to center less the fittings, every weld counted. THE ISOMETRIC Draw a run leg by leg, or sketch it with a finger on the grid. Turn the compass, swipe between the iso, the plan and the elevations. With the bender attached, every turn becomes a bend: the tube to cut, each bend's angle and centerline mark, and the roll between bends. THE CALCULATOR Feet, inches and fractions natively - 5'-6" + 3'-9" reads back 9'-3". Metric keys, angle mode with decimal and DMS entry, store and recall shared across every keypad in the app, session history, and your starred measurements one tap from the display. THE FITTINGS REFERENCE Every dimension of every fitting, from the published tables: butt weld, socket weld, threaded, flanges and grooved. Every page draws its fitting in section with the selected takeoff dimensioned on the steel. Set your root gap, socket pull-back, thread make-on and grooved separation once; every takeoff in the app follows. The Fitting Finder searches the whole set without leaving the calculator. THE TOOLS - Pipe Offset, plain or rolled: solve the triangle, then the fitting each end needs, the pipe between and its weight - Triangle: any two facts of the right triangle, the rest solved and drawn - Equal Spread: the advance that keeps parallel lines parallel through a turn - Miter Joints: cut angle, cutback, and the blank drawn flat on the bench - Fitting Cutdown: a 90 cut to any angle, with the three arcs to mark - Rolled Olet: set a roll angle with a tape measure - Tube Bending: one bend, a run of bends, or a run drawn as an iso - Pipe Information: bore, wall, circumference, and the weights you rig by IN YOUR POCKET Built for a phone held one-handed on a rack: big keys, answers that read at arm's length, and everything working without a signal. On an iPad the pages open out. PRO The calculator, pipe information and a selection of fittings in every connection are free. Pro opens the rest: a monthly or yearly subscription, or a lifetime license bought once that never renews.
