Game Master Helper vs NDT Nation

GMHelper helps Game Masters with reference material and generating random characters, loot, traps, encounters, names etc for TTRPGs and DnD games. All content is completely customizable. You can: - edit/update the existing example tables - create your own set of tables using the 'Create new' menu option in the main menu - share/download your table sets by using the share button on the main screen - import an existing table set use the 'Import file' menu option GMHelper works completely offline. All data is customizable, so can work with any TTRPG, including DnD 5e, ICRPG, ShadowDark etc.

NDT Nation is the field reference built by RT people, for RT people: 60 verified calculators, a standards reference library and three full exam-prep banks — all working offline at the shot location. 60 CALCULATORS • RT — film density by code, R-factors, source decay, exposure correction, geometric unsharpness, boundary estimate, blow factor, wall shot selector, IQI/density check, % sensitivity, HVL attenuation, inverse-square, isotope reference, film development, pipe schedule • UT / PAUT / TOFD — wavelength, near field, beam spread, Snell's law, angle-beam path, dB/amplitude, attenuation correction, thickness by echo, temperature correction, scan calculator, DAC/TCG helper, wedge refraction, TOFD setup • MT — coil shot, prod current, yoke lift test, demagnetization check • ET — depth of penetration, fill factor, phase/impedance, limit frequency • PT / VT — dwell time and dwell grid, lighting, coverage check • Welding — heat input, fillet weld size, pipe hi-lo, weld symbols, preheat/interpass, PWHT time and temperature, undercut acceptance, camber • Materials — carbon equivalent, bolt torque, weld volume, pipe clock position, F#/P# reference, hardness conversion, alloy/PMI reference, unit and temperature conversion ACCEPTANCE CRITERIA + INDICATION EVALUATION Pick the code, edition, pipe size and wall thickness and get the tolerance for each anomaly type computed for your actual wall — with a real reference radiograph on the rows that have one. The API 1104 engine evaluates an indication against the individual-length, worst-12-inch aggregate and percent-of-weld-length tests and tells you which one it fails. FILM INTERPRETATION WITH REAL RADIOGRAPHS Ten defect categories — incomplete penetration, IP due to high-low, elongated slag, porosity, cracks, burn through, hollow bead, internal and external undercut, incomplete fusion — each with real annotated films you can pinch-zoom, plus what it looks like on film and how it is graded. REFERENCE LIBRARY API 510, API 570, API 653, API 571 damage mechanisms, WPS/PQR to ASME IX, PT and UT code guides, PMI guide, CUI/coating and electrode storage — written in our own words from the governing standards and cited, never copied. EXAM PREP — 750 QUESTIONS • State card / radiation safety — 200 questions plus study notes and a timed mock on the real blueprint • CWI — 351 questions plus bullet study cards • ASNT Level II — 199 questions across UT, RT, MT, PT and ET Every answer comes with the explanation and the standard behind it. BUILT FOR THE FIELD • Fully offline — no signal needed at the shot • Big-screen mode: mirror your phone to a TV or monitor over AirPlay or HDMI for a film-density readout the whole crew can read across the bay • Customizable home — pin the tools you use, most-used surface automatically • Dark, one-hand interface that reads in bright sun or a dark bay Every formula is built from the governing standard — ASME, API, AWS, ASTM, ASNT, NCRP — and cited, not copied from another app. Reference only. This app does not replace your governing code, your written procedure or certified personnel. Radiation safety outputs are planning aids: always verify with a calibrated survey meter and follow your radiation safety program.
