App description
CRUMB offers an easy to use and interactive introduction to electronic circuits Fully realised in 3D, you can construct prototype circuits as you would at the workbench without the risk of terminal component failure or the hassle of ordering individual components CRUMB comes with a great selection of components to allow you to jump straight in to creating prototype circuits With the catalogue available, it is possible to study the workings of transistors & audio filtering, all the way to programming an EEPROM to run a basic program For the beginner, it is possible to learn and understand the basics of interactivity, and for the enthusiast it is possible to analyse and perfect prototypes before constructing real world models Using the built in oscilloscope and analysis views, it is possible to see clearly the interaction between components from within the wires themselves Through community feedback and suggestion, there will be many more components and features added.

How this analysis was produced. The sentiment score on this page is calculated from up to 300 of this app’s most recent reviews that pass Appeye’s quality filter (real, substantive, English-language text), scored individually using free, rule-based sentiment analysis. This identifies overall tone across many reviews at once and isn’t a judgement on any single review. A deeper analysis — pain points, praise patterns, and concrete recommendations drawn directly from review text using AI — is available for select apps; look for the AI report indicator on this page.
