App is great but please can you add as free components MOSFET gate driver and also give us the ability to choose source internal resistance and component internal resistance

Good for really basic examples. However, there are some very fundamental problems that the app needs to work through. Just look at the voltage output of a known good full bridge rectifier; the voltage output is all over the place when it should be positive dc.

It needs to be add more and more tons of other components. Type of all electronic like dc motor, switch, potentiometers and alll available electronic. Iam excited to see on next update

best circuit simulator I've seen so far. could you add more motors (ac synchronous motors, ac asynchronous motors, stepper motors, brushless motors, ...etc) and could you allow (when selecting multiple components) moving and copying them?

very easy to use...for me a very useful program to try many circuit combination, it will be good to have a multiple selection option to copy and paste...

Super. I loved the experience. I've just solved a problem that I'd been trying to solve for more than 3 months Easy to design your circuits. I wish you could add IGBT.

This app is quite a decent simulator. It isn't 100% accurate, for example I wasn't able to make a tesla coil work in there. On the other hand, it's really cool how it can interact with the device. What I quite miss is more I/O. The in part of I/O is great, but for the out part, the options are much more limited. As an example, I'd love to see a speaker there (not just beeper) but I don't have any idea if the android api allows it. It would be also cool to be able to create widgets.

Worked great for about an hour. Seams to work well . Then, it just refuses to work on a simple circuit I made up . It seems to have a time limit. It's really annoying. So, I was not able to test . Even after resetting, the save circuit is showing but not active. Solved the schematic doesn't like 3 connections to 1 point . One needs to understand the speed of the emulator, i.e., micro sec & and ms, etc . To get the correct results. If frequency was also shown might help, the novice .

It can immediately simulate once the circuit is done. An application that is light and excellent for people like trying to grasp the fundamentals pf electronics circuit. Offline, lightweight, and user-friendly.

works incredibly well for me (hobby/amateur). intuitive, easy to learn, well featured, stable, low on bugs. it seems to have all the components I want/wanted to test. i use it in conjunction with drawings, calculations and breadboards to learn, develop and build and to confirm values and function. very inpressed and happy with the product, the add-on features and payment structure.

Couldn't move logic gates around. Okay okay. Tap then drag. For we who 'grew up on' press and hold and drag doesn't work. Tap and drag works great though. Color changes on press and hold. Suggest adding performClick in onLongPress(), and make it an optional setting since a screen drag maybe confused a press and drag. It happens.

I'm new to electronics for the most part, and I've already learned a few decents things about components I haven't gotten from other apps. I love this app, and the updates as well. Keep up the awesome app, it's one of the main things my phone is used for. **Still an excellent app, but I realized I'm very incompetent, and hope you can add more examples. Such as dc/ac inverter, dc/dc buck booster, h-bridges, open coil? For things like a tesla coil.

Was useful enough I paid for the full gamut... However, I need a 2.81 nH inductor. I can't enter the ".81". I must truncate or round. I also tried "2811 pH" but they only allow up to three digit integers. I also have difficulty with "simulation speed" in that there's no indicator of how fast time is passing. If I need a half second or a five second delay on an action, I have no way to reliably verify that the outcome is timed correctly. Still, a good tool for learning and visualization.

Very happy with my experince so far. I'm an electrical engineer, I've used many simulation programs (TINA, ltSpice, etc), and this app is now my go-to for quick simulations. What makes it even better than pro EE software is the usage of the built in phone sensors. What would make it better: - MOSFET options like enhancement AND depletion type, Rds, Vgs threshold, Vds max, Qgs. - Example of buck converter with feedback control - Ability to move whole selection - Better wire interaction

Just a beginner... but really like it. So far just built a bridge rectifier to see if it actually simulated. Looks good. The oscilloscope seems to have some wonky values sometimes though. Buying it. Sensors: be nice to be able to have the device speaker as an item. Then one could use the microphone, develop a circuit, then output it through the speaker.

It's really awesome to be able to prototype circuits without spending a fortune on parts. But there seems to be too many quirks to make it enjoyable. For instance a switch. You click it twice to select and open it. But no it jumps all over the place. You lock it so it doesn't move but can't open it now. Adding a new part can inject it into the circuit causing negative actions. You try to move the part and it messes everything up. You can't move wire junctions. You have to del all connections....

What is the bias (in V) for a DC power source, please? Very useful simulator with some quirks. Adding a component drops it at the top left of the current view of the the circuit, so it may help to preposition that corner. Adding copper traces is tedious; to modify trace must delete/redo; can only connect to points on trace, not along a trace, no point running a long negative early as you cannot connect to it anyway. Contrast is too poor to distinguish traces with the light theme; Ocean is best
