Checklist improvements: - Exported PDFs now show the time as well as the date, and each export is saved as its own file. - Editing a checklist from History updates that record instead of adding a copy, and no longer counts against the free limit. - Export PDF stays off until you fill something in. - Sections close after Save or Reset. - You're no longer asked to continue a blank checklist. - Mock tests keep the question count you chose.

- Ring final continuity checks r1 and rn are within 0.05 ohm, as the On-Site Guide states. - Max Zs uses On-Site Guide Table B6 values. - PDF reports keep every caveat, and results clear when you change an input. - Checklists: "Save to History" saves, Reset discards, and the resume prompt offers "Save and Start New".

Three new on-site calculators, built from the IET On-Site Guide. • R1+R2 — predict the continuity reading for a circuit before you measure it. Pick the line and cpc sizes and the run length; you get the value at 20 °C and at operating temperature. • Zs from Components — Ze + (R1+R2), checked against the tabulated limit. Tell it whether your (R1+R2) is a 20 °C or an operating-temperature figure and it applies the right limit, so the temperature correction is never done twice. • Prospective Fault Current — Ipf from either loop, reporting the greater of PEFC and PSCC, which is the figure the certificate asks for. QUICK REFERENCE — 11 NEW CARDS • Maximum measured Zs for circuit-breakers, straight from Appendix B • (R1+R2) per metre and the temperature multipliers • A new Wiring identification & colours section — protective, AC and DC conductor marking • What the RCD test button does not prove, and when to test L2 and L3 • The six BS 7671 model forms and what a Schedule of Test Results must record PLEASE NOTE Ring Final has moved into the subscription tier. The free calculators are now Adiabatic, Max Zs and Prospective Fault Current.

A third batch drawn from IET Guidance Note 3, 10th Edition (BS 7671:2018+A4:2026). 46 NEW QUESTIONS — the bank reaches 556. PERIODIC INSPECTION: FREQUENCY AND SAMPLING (72 to 102 questions) • Who recommends the first inspection date and who sets each interval after it, and why the reason has to be recorded on the certificate or report • The recommended intervals for domestic, rented, HMO, commercial, educational and industrial installations — and that they are recommendations, not law • How inspection samples are set, adjusted and recorded, with the minimum sample sizes for switchgear, distribution boards, accessories and bonding conductors • The point most candidates get wrong: sampling applies to the equipment on circuits, not to the circuits themselves SAFE ISOLATION AND GS38, CLOSED BOOK (9 to 25 questions) • Overvoltage categories CAT II, III and IV, and the rule that a test arrangement takes the lowest category of anything connected in it • GS38 probe and lead requirements, and why a proving unit beats a nearby live supply • Capacitive charge, voltage thresholds and the planning a live inspection needs A new diagram walks through the decision procedure for setting and adjusting an inspection sample.

Sourced from IET Guidance Note 3, 10th Edition (BS 7671:2018+A4:2026). 30 NEW TEST PROCEDURES QUESTIONS Test Procedures grows from 48 to 78 questions, and the bank from 445 to 475. • Test instruments — instrument standards, calibration and the difference between basic accuracy and the operating error the BS EN IEC 61557 series actually permits in the field • Low-resistance ohmmeters, insulation resistance testers and earth fault loop impedance testers, including RCD uplift and the errors fused test leads introduce • Earth electrode resistance testers, RCD testers and phase rotation instruments • Expected and limiting values from GN3 Appendices A and B, including the maximum measured Zs tables and the two ambient temperature correction tables that are easy to confuse • Thermographic surveying, and where it does and does not stand in for inspection and testing TWO NEW QUICK REFERENCE CARDS • Test instrument accuracy and requirements • RCD test currents and expected times Quick Reference is now 15 cards. Every figure is taken from the published GN3 tables, with the section and page cited in the explanation.

This release rebuilds the app for the City & Guilds 2391-52 electrical inspection and testing qualification. • 445 exam-standard questions across 7 topics, written to BS 7671:2018+A4:2026 Part 6 • Open Book and Closed Book practice, mirroring how the real exam is sat • Weighted mock test — 60 questions, 120 minutes, matching the live paper • Four calculators: Max Zs, Ring Final, Adiabatic and Voltage Drop • Quick Reference — 14 cards covering test values, classification, safe isolation and test sequence • Digital Certificates — EIC, Minor Works and EICR with PDF export • Schedule of Inspection plus dead and live testing checklists • EICR Coding Guide and a Fault Coding Trainer for C1 / C2 / C3 / FI • Flash cards, UK English voice-over, progress tracking and iCloud sync

Compatibility with 3.0

1. Now you can turn off the 'shake to skip' feature in settings panel. 2. We have completely redesigned progress meter. The previous logic of averaging progress has been replaced with new logic that helps your track your progress better. 3. Now, the percentage shown in progress meter is actually calculated considering the total number of questions in that topic. 4. Also, now you can re-attempt the questions you answered incorrectly from progress meter tab. Look for the small arrow if there are any missed questions. 5. If you have any questions regarding how new progress meter works, please email me at iphone@uktheorytest.com 6. We have also made a lot of UI improvements.
