- Impact: Limits the app's versatility and usefulness for specific projects.
Outdated and Clunky User Interface: Difficulty selecting and deleting components, especially small ones, is a common complaint. The slider for setting component values is imprecise and frustrating. Wiring can be difficult to control.
- Impact: Frustration, wasted time, and a less efficient workflow.
Inaccurate Simulations: Some users report that the simulations are inaccurate, especially with certain components or complex circuits.
- Impact: Undermines the app's credibility and usefulness for design and testing.
Lack of Support: Some users report a lack of response from the developer regarding bug reports or feature requests.
- Impact: Feeling of abandonment and lack of confidence in the app's future.
Licensing Issues: Some reviews mention having to purchase the app separately for iPhone and iPad, which users find unfair.

Price Sensitivity: Some users feel that the app is overpriced given its limitations.
Strong Core Fan Base: Despite the issues, there is a dedicated user base that appreciates the app's core functionality and educational value.
Shift in Focus: Some older reviews mention the promise of future features (vacuum tubes) that have not yet been implemented. This may indicate a shift in the developer's priorities.

9. Conclusion

iCircuit has the potential to be a leading circuit design and simulation app for iOS. Its intuitive interface and real-time simulation make it a valuable tool for students, hobbyists, and engineers.
