What a STONKING application
OK so it has some issues, it crashes but at least you come back where you left. The actual application is fantastic. I usually use prototyping boards for simple stuff, but this actually works just as well and I can play anywhere anytime without frying numerous components. REALLY looking forward to this application advancing and its looking like the main reason for me to buy an iPad. A huge thank you to Frank for the amazing work he has done to just.Show lessJoolz the Bee
Nice idea...
I bought this app to test a couple of ideas and it seems that the engine is pretty good. I love the oscilliscope and voltmeter.
Only complaint is that it is highly unstable. At the moment i am half way through a simple bridge rectifier, it crashed out and now I can't open the app for more than 2 sec before it crashes out again. I have also had 2 lockups requiring a reboot of the ipad before it would work again.
Just upgraded to latest os and still same issues.Show lessNsmith64
Not there yet
It's UI is not intuitive and difficult to use. Try panning a page or finding an A/C source. The behavior of the parts drawer is very clunky. You tap to open it and if you take a moment to think, it will close on you. Why not "tap to close" and give the whole thing an icon in the control bar with the other icons... And those slider controls! They snap back like rubber bands when you get to the end! Why not use spinners?
You get a 7 segment display, but no decoder/driver!
The "Tips" are REQUIRED reading. Take my word for it. But I must say, for all its many flaws, it has potential to be great. Assuming the developer makes frequent updates to get pass the current issues. The last update (almost 7 months ago) isn't looking to good for that happening though. If this is all there is, I say keep your money...Show lessITooBelieve
Buggy, but it's so good I'll put up with the problems
This is far more than I thought a circuit simulator could ever get on the iPad/iPhone. It is a really, really impressive tool for simple experiments.
I love the moving dots to represent what the electric current is doing and the colouring of the wires. The resistor and capacitor values can be set by a slider or by typing in a value. You are able to set some parameters such as an LED's forward voltage, but the OpAmp appears to be an ideal one - you can't change offset currents, etc. The 'pin' in the Setting app is very useful, too - try it!
The UI can be a bit fiddly to use (especially on an iPhone), but it's fine on the iPad. The program could do with some in-program help about how to do things (I can't figure out how to turn the 'scope window off once it's on screen, for example).
The simulation speed on an iPhone 4 or an iPad can be slow with some of the larger circuits and with high simulation bandwidth, but the simple ones work just fine.
There are some odd bugs - the 'chest of drawers' icon doesn't always manage to take you back to your collection of prepared circuits and the 'Tips' window can be blank, for example.
I can look past the speed issues and the odd bugs - it's incredibly useful as it is now.Show lessBlowfishie
Needs Work
The idea is great but it's not really practical on an iPhone. Trying to select components to change their value is nigh on impossible unless you zoom right in (which is also quite difficult without selecting something by mistake). Great idea but needs a lot of improvement to make it worth buying. I also fear that the program is too processor intensive and is struggling to run well even on my up to date iPone 4. I hope you can make some improvements soon or it's one for the bin I'm afraid. Bring it out for Mac and I think it would be perfect.Show lessBongo Jim(only name left)
App hound
Wow , does this app ever need a lot of work it took me three hours to draw a simple bridge rectifer . Most of the time was spent trying to move components and deleting unwanted wires. What a disaster. It only crashed about 35 times in that three hours. I'm using a 64 GB iPod 4 and my 220 other apps are working just fine. Ten dollars is definately too much to pay for this app . Wait a few months before buying this app. , I'm sure it will come down in price, because right now this app is pretty much useless for any practical purpose. I don't know if I'll ever open this app again because I can do any diagram on paper with a pencil a thousand times faster than I could ever do with this app. This app is all glitter and hype and a lot of wishful thinking. Don't buy this App !!
( until it works like they promise )
I love the idea of this App but it doesn't work!Show lessBubblybob
Finally
I only used this app for a day and it cleared up so many questions. I have built circuits with the expensive programs that is provided at my University but none of them were as insightful as this program. All the books that I have read and all the power point lectures I sat through and all the labs can't amount to what I have in my hands now! I have a couple of projects coming and this will look great as a visual aid for a presentation. I will end this comment soon because no one likes long reviews.
Awesome job! I will put it to use for some homework too! (after all the hand calculations of course)Show lessExcited student
Great tool to have
Easy to use. Perfect for quickly sketching out an idea and experimenting with it.jm101010
Very impressed
I would have loved to have this app last semester during circuits lab. PSPICE has kept me from leaving my laptop at home, but no longer, and good riddance. This app is brainlessly simple to use, and the simulations are extremely accurate. I just finished using it for an electronics lab simulation using a network of transistors, and I was able to do so at a fraction of the time it took me in PSPICE with nearly identical results. The issues with this app are quite minimal, a couple crashes while tinkering with part settings but none lost any work.
Add the ability to do DC/AC sweeps and I won't have much need for anything else, although the multimeter is sufficient for most things.Show lessSatisfied747474
