What users say about CRUMB
From the 20 most recent App Store reviews in the US.
Users appreciate the educational value and core simulation concept but are frustrated by missing hardware components like microcontrollers and op-amps. Many reviews highlight that the mobile version appears abandoned compared to the desktop release, leading to bugs and a lack of updates.
Mostly negative (40% of recent reviews give 4–5 stars). People like it for its design, and its features and content. The main complaints are about price and subscriptions, and crashes and bugs. Recent reviews are more negative than earlier ones.
What people like
- Design: “I can learn to design circuits on my phone??”
- Features & content: “There are tools to let you see what the voltage and current are doing and warn you when you make a mistake that would fry something”
Common complaints
- Price & subscription: “This product seems more like a Beta release than a charge to use product”
- Crashes & bugs: “I love the app but please fix these bugs”
- Speed & performance: “I understand the admitted limitations but even adjusting settings to the highest performance does not help”
- Design: “Promising, but doesn’t work and the UI is subpar”
About CRUMB
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. For a full feature list and development schedule please visit the website http://www.crumbsim.com
