# Electronics Engineer Helper vs Math Derivatives

The clearest difference is rating: Electronics Engineer Helper at 4.8 against Math Derivatives's 4.5. Electronics Engineer Helper also leads on ratings volume (436 vs 15) and update cadence (monthly vs every 2 months). Math Derivatives's advantage is iOS requirement (11.3 vs 17.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Electronics Engineer Helper sells 2 in-app purchases, starting at $4.89 per year and Math Derivatives sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Electronics Engineer Helper holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Electronics Engineer Helper has 436 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 98% of Electronics Engineer Helper's written reviews are positive against 100% of Math Derivatives's, so the app with the better star average is not the one people write more warmly about.

Electronics Engineer Helper ships an update monthly, Math Derivatives every 2 months. The most recent releases landed on October 11, 2026 and September 29, 2026 respectively.
