What this app is. What it isn’t. What you could build.

One-liner

A compact, offline reference app for electricians with core electrical formulas, wiring diagrams, and code snippets, optimized for quick lookup on mobile devices.

Strengths

Highly rated (4.79) for reliability and accuracy of electrical formulas and calculations
Offline functionality works well—users praise access without internet dependency
Clean, minimal UI designed for fast navigation in field conditions
Includes essential NEC-style tables and wire gauge charts frequently cited in reviews
Strong keyword ranking for 'electric', 'engineer', and 'electronic'—high discoverability

Weaknesses

Users complain about missing common real-world scenarios (e.g., ‘no examples for residential panel upgrades’)
‘No search function’—reviewers note difficulty finding specific topics in large content blocks
Outdated content: one review says ‘some formulas are from 2010, not updated for 2023 NEC’
No visual diagrams—only text-based descriptions; users want schematics or icons
No user customization or bookmarking features—‘hard to save frequently used formulas’

Opportunities

Build a lightweight, searchable version with updated NEC 2023 compliance and real-world case studies
Add interactive diagrams and visual wiring guides that work offline
Introduce a 'Quick Lookup' mode with voice input or gesture shortcuts for field use
Enable user-generated notes and favorites—turn it into a personal field journal
Target apprentices by adding quiz mode and certification prep content
