Circuit-Design is a free educational utility for high school and university students to draw and simplify electrical circuits on iOS.
The App DNA
What makes this app unique?
The app removes the manual labor of network reduction for students by providing step-by-step graphical simplification of resistor, capacitor, and inductor networks.
For High school and university students studying electrical engineering or basic electricity.
What does it look like?
Key features
Calculates and reduces complex resistor, capacitor, and inductor networks with step-by-step graphical visualization.
Automates delta-to-wye, wye-to-delta, and current-to-voltage source transformations.
Determines resistance values for 3, 4, 5, and 6-band color codes.
How much does it cost?
The app is distributed as a free utility without visible monetization gates or subscription tiers.

Dormant developmentopaqueShow more...
Circuit-Design has entered a zombie state, with the latest release occurring 423 days ago. Development activity has ceased entirely, and there have been no updates to address performance or compatibility in over a year. The lack of any recent version history indicates the project is no longer being actively maintained.

Competitive landscape for Circuit-Design
How's the Education market?
Circuit-Design holds a 1-star rating across 2 reviews, reflecting a total lack of technical maintenance since July 2025. The absence of updates for 423 days positions it as a legacy utility rather than a competitive engineering tool.

Key takeaways for Circuit-Design
Where is it heading?
The educational utility market is shifting toward actively maintained, cloud-integrated platforms that offer broader component libraries. Circuit-Design remains exposed due to its 423-day update gap and critical interface regressions, which will likely result in continued user abandonment as students seek more reliable alternatives.
- The 14-month development freeze indicates the app is in terminal maintenance mode, which prevents any response to critical user-reported input failures.
- Persistent input failures in the diagramming tool drive negative sentiment, which will likely lead to further rating erosion as the user base remains stagnant.
The SWOT
- Step-by-step graphical simplification engine
- Automated delta-to-wye network conversion
- Expanding component library for university-level engineering

The app's primary risk is not its lack of features…
Read the full takeSince the last report: The app remains in a state of terminal maintenance, with no functional updates or shifts in its core utility. The only change is the explicit identification of poor developer support as a formal threat to the app's viability.
Bottom line
Circuit-Design requires a fundamental audit of its input handling and component library to regain utility, as the current state of technical neglect prevents it from serving its core educational purpose.
