Ironworker Pro vs RigMaster

Built by a working ironworker for the people who actually do the work — welders, ironworkers, fabricators, and riggers. Over 40 field references in your pocket, and every bit of it works offline, so a dead signal on the jobsite doesn't matter. No fluff. No login. No account. Just the things you actually look up on the iron. SEE IT, DON'T JUST READ IT 15 animated diagrams that show how the work really goes: Fillet welds — anatomy, watch it weld, common mistakes, what inspectors check Full penetration (CJP) vs partial (PJP) — watch a groove fill root to cap Weld symbols, joint types, groove types, multi-pass Laying a bead in stick, MIG, TIG, and flux core Welding positions — fillet, groove, and pipe Torch cutting, plasma cutting, heat colors, distortion Rigging hitches and weld defects THE TOOLBOX Eight calculators built for real jobsite math: Steel weight — beams and plate, pounds and tons Fraction / decimal / millimeter converter Triangle — rise, run, diagonal, angle Pipe offset — travel and run at any fitting angle Bolt circle layout — hole coordinates and chord spacing Rigging load — tension per leg as the sling angle drops Welding amperage by process and thickness Cut list — saves your pieces and totals the footage Plus favorites, recent tools, and a notes pad that stays put. SLING ANGLE VISUALIZER Drag the slider and watch the load multiply as the angle drops. A 30° sling puts twice the load in every leg. Know it before you rig it. PRO TAPE CALCULATOR Feet-inch-fraction math that works the way you talk. Punch in 12 ft 4 in 3/8 and add, subtract, multiply, divide. Convert feet straight to total inches for the plasma table. Area, volume, right angle, and rafter math built in. REFERENCE Weld symbols, electrode and settings charts, plasma cut charts, bolt torque and turn-of-nut tables, crane hand signals, material guide for A36, A572, stainless and aluminum, rebar, drill speeds, grinding discs, and more. SEVEN THEMES Iron, Arc, Ironblood, Field, Steel, Rose, and Daylight — pick whatever reads best in your light. BUILT FOR THE FIELD Works 100% offline No account, no sign-up, no ads Fast and readable with gloves on, in daylight IronWorker Pro is a field reference and training aid — not an engineering authority. Always follow your drawings, your WPS, the sling tag, a qualified rigger, and your employer's safety program. Welding and rigging are life-safety work. When in doubt, ask a competent person. Built for the iron. Trusted on the job.

RigMaster is the rigging calculator built for working riggers, crane operators, and signal persons. LIFT PLAN PDF (PRO) • Turn any calculation into a one-page lift plan: diagram, inputs, results • Room for notes and three signature lines — prepared by, signature, date • Share it straight to the supervisor from the toolbar IPAD & UNITS • Universal app — two-column layout on iPad, any orientation • Metric or imperial — kg and metres or lb and feet, switch any time • Live sling diagram with the angle and tension on every leg FREE CALCULATORS • Sling Tension — 2-leg picks by angle, or by sling length & height (the way you actually measure) • Hitch Capacity — vertical, choker, and basket capacity from YOUR sling's tag rating • Angle Reference — the tension multiplier table, always in your pocket PRO CALCULATORS • 3 & 4-leg bridles with rigid/flexible load sharing • Unequal Legs / CoG Offset — tension per leg when the center of gravity isn't centered • Load Weight Estimator — steel, concrete, aluminum and more, by shape and dimensions • Ad-free Built on first-principles trigonometry with warnings at 45° and hard alerts below 30°, following standard rigging practice (ASME B30.9 guidance). RigMaster is an estimation aid for qualified riggers. Always follow the sling tag, the load chart, and your site's rigging plan. COMMON QUESTIONS Does it work offline? Yes. Every calculation runs on the phone. No signal needed on site. Do I need an account? No. There is no login and no sign-up. What is free? Sling Tension, Hitch Capacity and the Angle Reference table are free. Pro adds 3 and 4-leg bridles, unequal legs with CoG offset, the load weight estimator and the lift plan PDF, and removes the ads. Metric or imperial? Both, switchable at any time — kg and metres, or lb and feet. Can I hand the result to the supervisor? Yes. Pro turns any calculation into a one-page lift plan PDF: diagram, inputs, results, notes and three signature lines. Does it replace the sling tag or the load chart? No. It is an estimation aid for qualified riggers. The sling tag, the load chart and your site's rigging plan always come first. Does it work on iPad? Yes. Universal app, two-column layout on iPad, any orientation. Terms of Use: https://ghapps1.wordpress.com/terms-condition/ Privacy Policy: https://ghapps1.wordpress.com/privacy-policy/
