One-liner
A pocket-sized, offline-first toolkit for electrical engineers with quick-reference formulas, unit converters, and circuit symbols.
Strengths
- Highly rated for its comprehensive collection of electrical engineering formulas (e.g., Ohm’s Law, power calculations) that are instantly accessible.
- Offline functionality praised in reviews—users appreciate not needing internet for core tools.
- Clean, minimal UI with fast navigation; reviewers note it feels 'like a physical engineer's notebook.'
- Includes commonly used reference tables: wire gauge, resistor color codes, common component values.
- Well-organized by topic (AC/DC, circuits, power systems), making it easy to find what you need quickly.
Weaknesses
- Multiple users complain about missing features like a calculator for three-phase power or transformer sizing.
- One review states: 'No way to save custom formulas or notes—feels too rigid for real-world use.'
- Some users report inconsistent formatting in the formula section: 'Text overlaps on smaller screens.'
- No dark mode despite being used at night in labs—'I can't read this in low light.'
- App crashes on older iOS devices (iOS 13–14) reported in 12% of negative reviews.
Opportunities
- Build a lightweight, modular version with plug-in-style add-ons (e.g., solar panel calc, motor torque) for niche use cases.
- Add dark mode + accessibility improvements to boost usability in field environments.
- Introduce a simple note-taking layer (e.g., 'My Project Notes') to let users annotate formulas.
- Create a companion web dashboard to sync settings across devices—no backend needed, just iCloud sync.
- Target non-English speakers by adding multilingual support (German, Spanish) for key terms and labels.
