“Awesome app, constant and powerful improvements”
This app was worth every penny I paid for it back when I bought it years ago. Since then, I’ve regularly used it at work and found it to be an excellent, quick tool to use. The most impressive aspect of this app are the constant and VERY impressive updates! Massive feature additions and very easy to use interface! The list of capabilities this app has makes it an amazing value for truly anyone involved in electronics.

Customer Reviews

Not Recommended

I came across this app when looking for a mobile way to design schematics. This app sadly doesn't let you do that (or at least from what I can tell), but it still looked promising. This lead me to download it.

Initially I was actually quite amazed at what it had to offer, and I clicked on the various features to try them out. This is where I began to get disappointed.

Basically everything in the app is "locked", which means you have to pay to use it. This is where my frustration occurs. The only feature which I can honestly say I still use is the 7400 series logic feature. Everything else is either plain garbage or has to be purchased.

So is it worth getting? Maybe. I don't think its worth it, due to the fact that very little features are available for free, but it MIGHT be useful if you pay for everything. Its hard to say.

I DO agree with the fact that not everything can be free, and the fact that the developers need to be rewarded for their efforts. However, I feel like the app provides so LITTLE features that it is almost impossible to want to take the chance to buy the PRO version, since the free version has so much to hate. Its just so frustrating that you almost immediately want to just get it out of your view.


The RLC Code functionality is useful to me. However, since the new version I now have to pay for the previous open functions. That blows, deleted!
