Have watched things evolve at an exponential rate from relay & rotary uniselector control through solid state control to computer control. From hands on to programming to operation. Now as a grandfather of 7, I was cruising the App Store and found this app and it has rekindled the interest I had as a 9 year old with my Phillips electronics project kit back in the early 60s. Initial reaction was “WOW! My Wife is going to kill me” Thanks for your hard work. ### 5/5 — Brilliant App *2024-03-27, version 14.5.01* I’m only an amateur electronics enthusiast building small kits and my own experimental designs but this app is brilliant for helping me figure out things. This app does stuff beyond my understanding. Maybe it came from Roswell. 😄 ### 5/5 — Nothing like it *2024-03-27, version 14.5.01* I don’t think anyone has a better app. Truly amazing! ### 5/5 — Mick *2024-02-01, version 14.5.01* I think this app is really such a brilliant tool and used it for several years and will carry on using it Thanks ### 3/5 — Umfang gut, Bedienung mäsig *2023-11-20* Schon Ewigkeiten auf meinem iPad aber hat sich in der Praxis als nicht besonders nützlich erwiesen. Zumindest wenn man es als Notebook, Projektplanung verwenden will: Import von externen Datenblättern, Sammlung von Weblinks umständlich oder gar nicht möglich. Verwirrung im GUI wo es z.B. eine Feld „Links“ gibt aber man kann dort nichts ablegen. Ähnlich für Dokumente. Suche nach Bauteilen mit nicht mehr aktuellen Internet-Datenbanken. ### 5/5 — Better Than Advertised! *2023-11-09, version 14.5.01* I bought this app several years ago and have used it off and on. Each time I’ve launched it I was informed that the app had been updated—which of course was a pleasant occurrence. The information contained therein has always been accurate and, while it don’t use it everyday, I have no plans to ever “not have it on my phone”. I recommend this app to anyone considering it. ### 5/5 — Awesome app *2023-10-17, version 14.5.01* Helped me out many times. Hard to remember all aspects of electrical engineering and this app is ready with information. ### 5/5 — A must have! *2023-10-10, version 14.5.01* This is the most comprehensive and appropriate set of tools that you will need. Each is easy to use and very accurate. The interfaces are very intuitive. Highly recommended. ### 5/5 — Top App *2023-10-07* Das ist einer der ganz wenigen Apps die ich gefühlt schon immer installiert hatte und die auch bleiben wird. Man kann alles mögliche schnell und unkompliziert nachschauen. ### 4/5 — Calc: equation dsappears *2023-09-08, version 14.5.01* Hoping for an update. The equation still vanishes after the answer appears on the right side of the screen. A simple 37+63=100 but, the 37+63 disappears. ### 5/5 — Great Tool *2023-07-08, version 14.5.01* This app is amazing for electronics. So many resources and features stuffed in this thing. ### 5/5 — Electronic TB *2023-06-11, version 14.5.01* Great App for anyone interested in electronics. ### 5/5 — Eine Datensammlung mit Herz und Verstand *2023-05-30* Wie oft fehlt meinem Gedächtnis ein elektronisches Datum oder ich muss mal kurz nach einem Bauteil nachschlagen. Einfach großartig, dass sich einer diese Gedanken gemacht hat und diese APP gebaut hat. ### 5/5 — Best electrical app out there! *2023-05-22, version 14.5.01* Ive had this app for about a month or so. What I originally got this app for was drawing out schematic just basic stuff but this app has so much information and knowledge behind it. I have only begun to scratch the surface on its capabilities. I would say I’m a novice to mid level when it comes to electronics more of a hobbyist but this app has pushed me to learn more outside of my day to day applications. This is well worth the money so many good tools and information. ### 5/5 — Indispensable! *2023-04-13, version 14.5.01* This app. continues to be one of my most important apps. Thank you Marcus for continuing to keep this going! ### 5/5 — What used to be in several books or desk items. *2023-03-18, version 14.5.01* Very handy, I print saved page images for reference where iPhone is not safe at hand. Great fast reference to specific items I may have suggestions but not for now. Thanks for efforts ## Most critical reviews (10 lowest-rated) ### 1/5 — Misleading *2025-01-11, version 14.5.01* The image of the page showing conponents shows vacuum tubes, but after purchasing, apparently, tubes are not available to use to construct circuits. ### 1/5 — Non-functional application *2023-04-20, version 14.5.01* The circuit editor is non-functional with touch input, and the app is virtually useless on the iPhone. I fought $7 of digital garbage. No auto save, you just lose work, whole files disappear. App constantly crashes. ### 1/5 — 无法运行，死机 *2018-05-01* 打开app就死机了，退出重新运行也不行，2018版本ipad，网络正常，第一次运行直接跳出加载新闻，然后死机，第二次运行提示更新库然后死机，第三次运行，直接死机。 **Developer response:** 最近的更新已修复此问题。请尝试。请让我知道如果错误仍然存​​在。谢谢！ This issue has been fixed with the recent update. Please try. Please let me know if the error still exists. Thank you! ### 1/5 — 使用不了 會當掉 *2018-01-21* 使用不了 會當掉 **Developer response:** 這是不正常的。請通過support@creating-your-app.de與我聯繫，我們把它固定在一起。 ### 1/5 — Freeze almost time *2018-01-12* The app freeze and dont work. Can’t use **Developer response:** This is not normal.

Please contact me via support@creating-your-app.de and we get it fixed together. ### 1/5 — Don't work anymore *2017-12-04* The app was good but now, it does not work on ios 10.3. Both on iPad and iPhone. It freezes seconds after opening. **Developer response:** Hi Cibim, please contact me to get this resolved. The App works fine on iOS 10.3. ### 1/5 — What does it do? *2016-01-17, version 9.01.01* Not clear what the app does. From the blurb it looks like I should be able to design a circuit on screen in the app. All I have been able to do is make a list of components but there is no obvious way to draw a circuit to connect components together. If it's just a database of component specifications, then it was a waste of my time and money. ## Most praised reviews (10 highest-rated) ### 5/5 — A truly useful app! *2026-03-22, version 14.5.01* Has everything you could possibly need as an electronic technician or experimenter. A+ ### 5/5 — Sehr begeistert *2025-10-08* Ich nutze es schon seit Jahren, und es gibt schon seit Jahren Updates ohne nervendes monatliches Abo. ### 5/5 — Once *2025-09-22, version 14.5.01* You only have to use this app once to understand how much information is now at your fingertips. And the more you use it the more you will discover how detailed it gets. Then you’ll be amazed at how often the app is updated and maintained. I have used numerous electronics apps over the years, this is the one that hasn’t been removed from my devices. ### 5/5 — Mr *2025-04-16, version 14.5.01* THIS IS A FANTASTIC APP. I HAVE HAD IT FOR ABOUT 4 MONTHS BUT IT STILL SURPRISES ME WITH THE DEPTH OF KNOWLEDGE AND USES IT CAN BE PUT TO. AS A TEACHER OF ELECTRONICS I FIND IT INVALUABLE. WHEN MY IPAD WAS STOLEN I HAD TO SPEND HOURS SEARCHING FOR THE SAME DATA, AND IT WAS NEVER PRESENTED IN SUCH A GREAT FORMAT. THE APP WRITER NEVER RESTS ON HIS LAURELS AND IS CONSTANTLY ADDING ORE USEFUL FUNCTIONS. ### 5/5 — Super *2025-03-17* J’ai cette appli depuis bon nombre d’années une appli qui est suivit pas ses créateurs avec des mises à jour régulières indispensables sur bien des domaines je conseille sans modération !! ### 5/5 — This is a very handy resource for electronics *2025-03-15, version 14.5.01* I won’t say I use this app every day but when I need it it always provides the answers I need. Great app. ### 5/5 — ExceptionalToolbox Pro Version *2025-03-13, version 14.5.01* Exceptional toolbox with great content, easy to visualize the devices and select. A must for anyone from professional EE to DIYer. ### 5/5 — Best app *2025-01-19, version 14.5.01* This is one of the apps I use on a daily basis for electronics and electrical repair, this is not available on Samsung so I will never switch phones I can’t loose this app ### 5/5 — Logiciel utile *2024-12-14* Logiciel utile aussi bien à l’amateur d’électronique qu’aux professionnels du domaine par la possibilité de faire des calcules rapidement sans avoir à rechercher les formules pour par exemple calculer un circuit pendant un temps mort Concepteur à l’écoute des utilisateurs ### 5/5 — Very useful *2024-12-04, version 14.5.01* I use this almost every day while revising circuits and figuring out suitable component substitutions --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
