One-liner
A free, offline reference app for electricians with code tables, calculations, and NEC quick lookup tools.
Strengths
- Provides essential electrical code references (NEC) in a compact, searchable format
- Fully works offline—critical for field use without internet access
- Well-organized layout with intuitive navigation for common tasks like wire sizing and circuit breaker selection
- Highly rated by electricians for reliability and usefulness in real-world jobs
- Free version offers substantial value with no ads or paywalls
Weaknesses
- Limited to basic reference; lacks advanced tools like load calculations or custom project tracking
- User reviews mention 'no explanation of why' certain values are used—just tables
- Interface feels dated; some users complain about small text and poor touch targets
- No integration with other tools (e.g., PDF exports, cloud sync)
- Missing recent NEC updates (2023/2024) in several sections per user feedback
Opportunities
- Build a lightweight, modern redesign with responsive UI and dark mode for better field usability
- Add context-aware explanations (e.g., 'Why is this wire size required?') using simple tooltips
- Introduce a paid tier with dynamic calculators (e.g., branch circuit load, conduit fill) while keeping core reference free
- Support NEC 2024 updates as a key differentiator in a niche market
- Enable exportable PDF reports from saved calculations for job documentation
