Love the PDF producer. Looks so good and simple to use. Support was super quick and really helpful! This will be my go to, every-time. Thank you! ### 1/5 — Can’t log in *2026-05-17* I paid for this app via my apple account a few years ago and it was great but just went to use it after a while and new stuff has locked me out 😡 **Developer response:** Hi, the new log-in is to facilitate syncing of the forms data, so if you change device the data will sync to it. It’s free to sign up and log in. ### 5/5 — Dave Barnes *2026-05-15, version 15.1.31* Brilliant ### 5/5 — Electrical tools and references *2026-04-29* This is outright the best app I have downloaded. Well worth the money if you are an electrician. **Developer response:** Thank you for your 5 star review, it motivates us to make it even better for you. ### 5/5 — Use it every day *2025-11-26* A brilliant app and worth every penny. Concisely gives you the information you need when filling out certificates or doing on the fly cable calcs. I’d be lost without it **Developer response:** Thank you for your 5 start review, we shall continue to work hard and innovate and improve the app for you. ### 1/5 — dissatisfy *2025-08-18, version 10.42.23* I regret purchasing this app for £25, thinking it would provide useful electrical tools. Instead, it's a complete rip-off! As soon as you open it, every single feature is locked behind another paywall. You're forced to pay extra for basic functions that should have been included in the original price. The app is absolutely useless without spending even more money, making the initial purchase a total scam. There are free alternatives out there that offer better functionality without all the greedy upselling. Do not waste your money-this app is a dishonest cash grab. I want a full refund! ### 5/5 — Good app *2025-08-14* Fantastic app use it every day as a domestic sparks , all I need in one place…keep up the good work.. ### 5/5 — Stevie *2025-03-25* Considering this app /product is free for the most part, it is excellent. I look forward to trying the certification app. ### 5/5 — Brilliant *2025-01-17* Use the app pretty much everyday when at work. Saves having the regs book with you and the calculator is a massive time saver. ### 5/5 — Well worth it *2024-10-03* Brilliant bit of kit that consolidates all the information needed daily as an electrician ## Frequently asked questions about Electrical Tools and Reference ### What does the Electrical Tools and Reference app do?
