# Electronics Kit vs Resistor Calc+

The clearest difference is in-app purchases: Resistor Calc+ at none against Electronics Kit's 5. Resistor Calc+ also leads on rating (5.0 vs 4.8). Electronics Kit's advantage is ads (none vs shown) and review sentiment (91% vs 67%). On price, update cadence and device support there is nothing between them.

Both are free to download. Electronics Kit sells 5 one-off in-app purchases. Resistor Calc+ asks for nothing beyond the download.

Resistor Calc+ holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Electronics Kit has 65 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 91% of Electronics Kit's written reviews are positive against 67% of Resistor Calc+'s, so the app with the better star average is not the one people write more warmly about.

Electronics Kit ships an update every 6 weeks, Resistor Calc+ every 2 months. The most recent releases landed on October 10, 2026 and October 7, 2026 respectively.
