Lost faith with this. **Developer response:** Hi, have you allowed for the temperature correction factor of 1.2 in your manual calc? ### 4/5 — Good content *2022-05-19* Good content with the references to look at and calculators at the press of a button however my only gripe is that it’s a bit too expensive in my opinion. I have purchased it and intend to keep using it to make it up to myself but that’s just my opinion. Overall very good app for sparkys who need to calculate on the go. ### 5/5 — 10/10 App *2021-08-18* I never ever ever leave reviews. But with this app I make an exception. This app is easily THE MOST USEFUL app I have ever owned. I use it daily and it has absolutely everything in one convenient place. If you are discouraged by the price let me tell you… if it was £50 I would pay for it just because of how useful it is. Amazing app and we’ll worth a purchase! **Developer response:** Thank you for your feedback, it’s nice to hear after the amount of work we have and continue to put in to this app. ### 4/5 — Darren *2021-06-19, version 10.42.4* Seems a very good app hoping for more updates/information to be put on. ### 5/5 — Antw14 *2021-05-09, version 10.42.4* Brilliant app ### 5/5 — Information at your fingertips *2021-04-08* Had this app for sometime now and really recommend it for any electrician, engineer, trainee and designer. It provides a great level of information at the touch of a button and prevents having to carry reference books out on site. ### 5/5 — Good on site reference *2021-01-13, version 10.42.3* Great for onsite guidance without a lot of books to go thru ### 5/5 — Brilliant *2020-11-25* Very good app comes in so handy. Worth the purchase. Not sure if this updates when the others do as my cable calc app updated and this one didn’t ### 5/5 — Best Electrician App!!! *2020-07-05, version 10.42.2* By far the best App for Electricians that work in Domestic , Commercial , Industrial and Test & Inspection Industry. The volume of information is endless and is frequently up dated to comply with the current IEE Wiring regulations. Extremely handed app to have on your phone at a glance! A must for all Electricians!!! ### 5/5 — Ze *2020-06-01, version 10.42.1* Zen See seezrss xerox ### 5/5 — Great app *2020-04-19* Love this app, very handy with lots of info on it , brilliant for when on site and no access to reference books **Developer response:** Thank you for your review. ### 5/5 — Great app *2019-08-22* Easy to use and convenient when on the go ! **Developer response:** Thank you for your feedback. ### 5/5 — Referencing and calculating *2019-08-20, version 10.41* Really good pocket guide and tool to use on a daily basis within the electrical industry. ## Most critical reviews (10 lowest-rated) ### 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. ### 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! ### 1/5 — Fantastic app let down by ads *2022-03-06, version 10.42.10* Thought I’d download this app as a reference when I’m unable to use BS7671 due to the adverse weather. How ever I’ve just used the app to find its full of ads 👎🏻 I’m sure I paid £15.99 which is annoying as paid apps are generally not embedded with ads Other than the ads it’s a very useful app. ### 1/5 — Disappointed *2021-05-03, version 10.42.4* After the app clearly displaying max Zs for MCCBs you have to buy an additional app to get them ### 1/5 — Horrendous *2019-10-07, version 10.41* Not worth the money at all. Don’t buy it, it’s just got basic electrical information. Rhubarb ### 1/5 — M *2015-09-20, version 3.0* Out of date Zs values. Has not been updated to amendment 3. ### 1/5 — This app doesn't work *2014-01-11* Every time I type in the values I press next to hopefully be able to press calculate and it shuts down. I want my 5 bucks back please ### 1/5 — no good *2013-10-02, version 1.0* could be good if it worked,, but every time i hit the next button in formulas it crashes dont buy till updated ### 1/5 — Cable Calculator *2013-07-04, version 1.0* Generally I'm happy with the app, but the extremely important cable calculation section lacks a comprehensive range of cables, does not allow cable size selection, and the +1 button only allows the selection of 1.5mm T/E cable. It was anticipation of the convenience of having a simplified form of cable calculation on site, that convinced me to purchase the app in the first place... You desperately need to sort this out! If this section had functioned accurately, I would have had no hesitation in awarding this app a five star rating. However, I feel terribly let down by the unprofessionalism of releasing an app to people who need to rely on its accuracy for the safety of their customers, and the avoidance of prosecution. You only have yourselves to blame for my rating. ### 2/5 — Crashes *2013-12-03, version 1.0* Have emailed the developer no reply the app crashes on the first two parts the keyboard should show done once the data has been entered but shows next , when this is pressed the app crashes the R1-R2 part runs fine. ## Most praised reviews (10 highest-rated) ### 5/5 — Amazing App & Support *2026-06-24* Such a great app, really good to have to hand and support. 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! ### 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. ### 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 ### 5/5 — Pro certs app *2024-09-11* Absolutely the best electrical reference guide you can get. Use several times a week. Please support and keep it online. ### 5/5 — Andy *2024-03-07* Outstanding app simple with all the information needed --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
