I have been in the Electrical field for ten years and thought I had a big area of expertise but as I kept reading and learning I am definitely humble to say that I am glad to have found this app!

Thanks. *2019-11-22, version 1.0.3* Great. ### 5/5 — Good Work Mike *2019-09-25, version 1.0.2* It’s been a long time coming for your app.....look out for Mobile Electrician app! Your app is American Made versus Ukrainian ### 5/5 — Nice Work *2019-07-15, version 1.0* Great tool..Hope to see more features....don't mind paying extra. ### 5/5 — Great job Mike *2019-06-28, version 1.0* This is awesome I’ve been waiting for a year, saw it at the seminar and wanted then. Thanks for the release, this will definitely make me more efficient. ## Most critical reviews (10 lowest-rated) ### 1/5 — You can’t email the information you have to forward *2025-10-22, version 1.0.39* It’s a good app, but it has the option to email the results, but it won’t let you. It’s frustrating. ### 1/5 — Outdated *2024-06-26, version 1.0.34* Info in this app is outdated and for the most part useless to any decent electrician ### 1/5 — Needs a whole overhaul *2023-05-02, version 1.0.29* The content within the app is not bad, but how the content is set up is. I purchased the Journeyman Library for exam prep. Anytime I start one of the videos when I come back I have no idea what part I was on when I left last. It would be nice to have some-type of completion system when it comes to the video series. There is a bug where if you go wide screen and exit the video player and come back you are unable to go back wide screen. The app is not user friendly it’s an outdated app that needs to be refined and made user friendly. ### 1/5 — Not ready for prime time. *2022-04-20, version 1.0.21* Obviously not ready for prime time save your time and energy ### 1/5 — Disappointed *2019-07-15, version 1.0* Yes the calculator works. And you pay .99 for it. The rest is quick links to a website. Save your money, bookmark the site in your browser and do a free calc. Lifelong mike holt fan, he’s always been an inspiration but the app is straight garbage. ### 3/5 — Need more *2025-03-11, version 1.0.36* Take transformers at least to 225kva. 112 isn’t enough for this to be useful. ### 3/5 — This guy wrote your textbook *2024-03-14, version 1.0.34* If you don't know who this guy is, you likely read his textbook. On his TV show, Holt plays a gameshow host, and throws topics at residential, commercial, and government tier electricians. The government guy always has to code, infinite budget. And as you go down tiers you learn how the budgeted tiers deal with it. ### 4/5 — What version of the nec is this using ? *2024-02-23, version 1.0.34* Seems useful but load calc a little clunky ### 4/5 — NEC 2020 *2022-07-13, version 1.0.21* Will there be an update to this app based on NEC 2020? The drop down menu only goes up to NEC 2017. ### 5/5 — Great app *2024-10-05, version 1.0.34* Perfect app. I really like how it gives the code article with the results. ## Most praised reviews (9 highest-rated) ### 5/5 — Great in the tool box *2024-09-13, version 1.0.34* Outstanding app to verify calculations. The best parts is it gives reference to code sections so you ca read for your self. ### 5/5 — Awesome tool *2024-03-26* Absolutely essential for on the spot reference. Incredible. Thanks so much. ### 5/5 — Rodriguez Electrical Contractor *2023-08-11, version 1.0.30* Excelente tool for the field. ### 5/5 — Great Jobsite Resource *2023-05-29, version 1.0.30* This app is a great resource for the industry! ### 5/5 — Great app *2022-12-07, version 1.0.27* Makes our trade simple!!! Thank you ### 5/5 — About time *2022-02-15, version 1.0.21* This is exactly what every journeyman should have with him in preparation for his testing for licensing, is a great asset, THANK YOU MIKE HOLT SINCERELY CELS ### 5/5 — Great App *2021-06-16, version 1.0.20* I love this app and use it to do service calculations in a hurry every day. I would love to see an option to print out my load calc instead of having to email it to myself and printing the email. I also wish that the previous information would be erased when starting a new calculation. Other than that it is great! ### 5/5 — Awesome app!! *2021-05-01, version 1.0.9* Handy tool for electricians ### 5/5 — Nice work mike *2021-02-21, version 1.0.9* I am getting ready to sit for masters elec. License. And I have to say mike you are a huge help. Thanks for all the hard work to make things simple to understand in layman’s terms. I appreciate it! Love the app and hope I can get your program on dvd soon. Thanks! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
