Ratings and reviews

My experience with the SimuBus app is that it is useful for creating and testing electrical wiring diagrams, but I encountered a problem when connecting lamps in series. The parallel connection works properly, but the series connection does not work even when the wiring is arranged correctly. I hope the developers can make the wiring connections and errors clearer and improve the simulation so that bugs like this can be detected and fixed immediately.

Good app, but if the developers could lower the price, i would definitely purchase it. also the option to pay for lifetime purchase does not work.

Overall, it’s great. But I have a suggestion for a feature that would be really really useful, being able to upload images into the canvas. like wiring diagrams, schematics etc. That way, we could follow the diagram directly on the simulation canvas. That would be a great feature and also a landscape mode. so 4 stars for now.
