Bubble Level - Calibrated 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.

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 standards and every drawing showing where the number actually runs on the steel. 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. Every answer is ready to copy, store, or feed the next sum. THE FITTINGS REFERENCE Every dimension of every fitting, from the published tables: - Butt weld (ASME B16.9): all sixteen types - Socket weld (ASME B16.11): classes 3000/6000/9000, measured to the socket bottom, your pull-back applied - Threaded (ASME B16.11): all ten types including street elbows, plugs and bushings - the make-on subtracts, because a thread makes the pipe longer - Flanges (ASME B16.5): all six kinds, classes 150-2500, raised-face rule built in - Grooved (Victaulic): elbows, tees and crosses, with the groove specification itself - gasket seat, width, diameter, and the lightest wall that may be roll or cut 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 TOOLS - Pipe Offset: solve the triangle from any two facts, then get the fitting each end needs, the pipe between, and its weight - Equal Spread: parallel lines turning together - the advance that keeps the spread equal through the corner - Rolled Offset: roll, set and advance into one travel, with the bend angle and the roll angle told apart - Miter Joints: cut angle, cutback, and the blank drawn flat on the bench, marked for cutting - 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: the four lines of a bend, worked out from the drawing's centerline, with the gain falling out of them - Tube Bending Run: tube, bends, tube - every line to mark and the length to cut, for the whole run at once - Pipe Information: bore, wall, circumference, and the weights you rig by - empty, full of water, and per foot THE FITTING FINDER Search the whole reference set without leaving the calculator. It opens on the size and connection you work in, keeps a shelf of the fittings you starred, and a click on any result opens everything that fitting measures - inside to end, outside to end, the with-gap variants, the bend - ready to drop straight into your sum. IN YOUR POCKET Built for a phone held one-handed on a rack: big keys, answers that read at arm's length, and everything reachable without a signal. On an iPad the pages open out - the drawing beside the numbers rather than above them. BUILT FOR THE TRADE Answers read the way a tape does. Drawings are to the steel's own proportions. Arrange the menus your way, star what you use, and it all persists. Some tools are part of Pro. The calculator, the fittings reference and pipe information are free to use.
