One-liner
A pocket-sized, offline-first toolkit for electrical engineers with circuit calculators, unit converters, and reference tables.
Strengths
- Highly functional offline tools (e.g., Ohm's Law, resistor color code calculator) praised in reviews
- Clean, minimal UI optimized for quick calculations without distractions
- Comprehensive reference data (wire gauges, component values, common symbols) valued by students and pros
- Consistently rated 4.6+ across 1371 reviews with strong retention signals
- Top-50 keyword rankings in 'electronic', 'engineering', and 'electric' show strong search demand
Weaknesses
- Users complain about missing features like battery life calculators or AC/DC analysis tools
- No dark mode despite repeated requests in reviews: 'Would be great if this had a dark theme'
- Some users report outdated content: 'Values for modern components like SMD resistors are missing'
- Limited customization: 'Can't save favorite calculations or create custom formulas'
- No cloud sync or backup: 'I lost my settings after reinstalling'
Opportunities
- Add dark mode and accessibility improvements to address top user complaints
- Introduce modular add-ons (e.g., 'AC Analysis Pack', 'SMD Component Guide') via in-app purchases
- Build a lightweight companion web app for syncing favorites and sharing calculation templates
- Leverage high keyword rankings to target niche sub-segments (e.g., 'Arduino electronics', 'HV engineering')
- Offer a free tier with core tools + paid upgrade for advanced features to increase conversion
Competitors
