And it's free. A no-brainier for anyone playing with circuits. ### 5/5 — Simple and great!! *2012-10-24, version 1.0.1* Brilliant this stops me making all those mistakes of wrong resistor!! ### 5/5 — Super helpful *2012-10-13, version 1.0.1* Foolproof ### 5/5 — Very nice *2012-08-29, version 1.0.1* Useful, straightforward and free. ### 5/5 — Easy and straight to the point... *2012-08-28, version 1.0.1* Great and simple app to use for everyday electronics. ### 5/5 — Great app *2012-01-15, version 1.0.1* This app is a great reference tool. I look forward to any future updates that would add more info. Hats off to the devs. ### 5/5 — looking fotward to 'breadboard' *2012-01-14, version 1.0.1* if possible！ ### 5/5 — Brilliant *2012-01-13, version 1.0.1* For a totally free app this is great, better than eTools even. If there was some add-on modules for IAP, (Arduino reference, oscilloscope, example circuits, 555 calculator) would happily pay. Well done to the devs! ### 5/5 — Nice looking, easy to use *2012-01-11, version 1.0.1* A useful tool that looks and preforms great. Very easy to use. ### 5/5 — Beautifully constructed app, great tool for electronics hobbyists. *2011-09-24, version 1.0* Clean layout, a pleasure to use. ## Most critical reviews (10 lowest-rated) ### 1/5 — Crashes on my iPod 5th gen *2016-01-05, version 2.0.4* Shows menu/home screen for split second then goes black. Same every time. Not yet Able to use the app ### 3/5 — Why Perfboard? *2021-06-14, version 2.0.4* The app is very very basic. It’s a nice little app though that covers the very basics of Ohms Law. There’s a bit about resistor colour codes and caps. A nice touch is the info about LEDs and voltage dividers. To be fair; there’s enough info here for you to keep the magic smoke inside an LED and get it to light up, and in all honesty that’s where the journey begins. There’s no point in scaring people with circuit analysis, truth tables and sketches. ### 4/5 — Excellent but could be better:- *2011-12-07, version 1.0.1* Very well presented App, am liking the hand drawn theme over other App methods used to gather and display information for the covered electrical components. One required update which in my view would make this App a 5 star winner would be an enhancement to the LED Limiting Resistor calculator by providing resistor details for multi LED's, wired either in Series or Parallel. ### 5/5 — Abandoned? *2023-02-26, version 2.0.4* Been trying ti buy the paid version for a long time. Apple wont let me do it. I believe this app has been abandoned by its dev. Too bad, looks like its the best thing out there ### 5/5 — Great! Except for 1 Ohm *2021-01-16, version 2.0.4* Very handy... Worth the small price to unlock other features. NOTE: There is one bug, the app reports a 1 ohm resistor as a 10k resistor... Only issue I have found.. ### 5/5 — Just the Job *2018-12-23, version 2.0.4* Just realised I had not written a review yet, but have to say it is just the job for me being a casual user of this stuff and never remembering the calculations as I have a head like a sieve. Very handy having the ability to do the calculations on the fly. I note it hasn’t been updated for a while, so I do hope it will continue to work. I’m on IOS 12.1.3 and it works fine. ### 5/5 — Very Nice *2018-07-23, version 2.0.4* This is a very cool app, I’ve purchased the Pro Version and I recommend you to do the same, you’ll get more useful tools that I am sure you’ll enjoy 😊 Keep up the good work!! @Ed Rivera ### 5/5 — Wow this is great! *2018-01-29, version 2.0.4* Cannot saw enough. As a hobby electronics builder I can not believe how well this app works. I use the LED and resistor function the most. ### 5/5 — Excellent app and creator (vaper friendly) *2015-06-06, version 2.0.2* I can't speak enough how well the app works and looks. Puts all others in the realm to shame. Another plus is now with a watts counter, coil builders can now build within safe limits. A must have for any vaper out there. This came as a suggestion to the creator who is more than willing to hear you out. Simply amazing! Highly recommended. ### 5/5 — Simple and useful *2013-10-29, version 2.0.1* Simplicity ## Most praised reviews (3 highest-rated) ### 5/5 — Very handy, good interface, works well *2013-02-24, version 1.1.0* I'll pick up electronics for a while, then get busy with other things, and not pick it up for a few months. This app is well designed, just enough reference information, and I found the LED voltage limit calculator really useful. ### 5/5 — Nice app. *2013-01-24, version 1.0.1* Nice and easy interface. Handy tool. ### 5/5 — Good app *2013-01-03, version 1.0.1* This is a handy app to have. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
