RT Helper vs NDT Wizard

RT Helper is a professional mobile tool for industrial radiographic testing (RT). It helps inspectors perform exposure calculations faster, avoid common mistakes. RT Helper supports both X-ray tubes and the most common isotopic sources (Se-75, Ir-192, Co-60). Designed by an experienced NDT specialist, the app focuses on accuracy, usability, and real field requirements. FREE VERSION FEATURES • Exposure time calculator for Se-75, Ir-192 and Co-60 • Exposure time calculator for all available X-ray tubes • Voltage and IQI selection based on material and thickness • Up to 4 customizable presets for quick switching between parameters • Built-in exposure timer with sound notification FOR WHOM RT Helper is created for: • RT Level I–III inspectors • NDT technicians working with film radiography • Students preparing for RT certification

Full access requires an auto-renewable subscription — Monthly (£3.99/month) or Annual (£34.99/year, includes a 7-day free trial). All features listed below are included in the subscription. NDT Wizard is the inspection handbook for working NDT technicians — built by technicians, for technicians. Every calculator, acceptance criteria table and reference guide you reach for on shift, in one app that works fully offline: on the deck, in the ditch, or offshore with no signal. CALCULATORS • UT — beam paths, skips, sound path, dB drop, near field, beam spread • PAUT — sectorial setup, aperture, wedge geometry • TOFD — PCS setup, dead zones, depth from time-of-flight • Flaw interaction — BS 7910 conditions & API 1104 cases • RT — geometric unsharpness, IQI sensitivity, density • EC, MPI & PT — frequency/depth, field strength, coverage • PCS setup aid, AUT band riser, acoustics & more ACCEPTANCE CRITERIA Summarised weld acceptance tables from ISO 5817, ISO 10675, ISO 11666, ISO 10863, DNV-ST-F101, ASME B31.3, ASME VIII and API 1104 — with an indicative flaw checker. REFERENCE • Defect library with significance rankings • Weld prep geometries, material velocities, sizing methods • Interpretation guides — characterisation flow, AUT strip charts • UT simulator with A-scan and beam section view • NDT certificate tracker with expiry reminders — stored on your device Built for UT, PAUT, TOFD, RT, MT, PT and AUT personnel working to ISO, ASME, API and DNV codes. A field reference aid for qualified NDT personnel. Always verify against the applicable procedure, specification and standard before any inspection decision. No data collection — everything stays on your device. — Privacy Policy: https://ndtwizard.co.uk/privacy-policy.html Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
