Verdict
The clearest difference is in-app purchases: Electronics Reference Toolkit at none against Electronics Kit's 5. Electronics Reference Toolkit also leads on update cadence (fortnightly vs every 6 weeks). Electronics Kit's advantage is ratings volume (65 vs 7) and device support (3 vs 1). On price, rating and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Electronics Kit sells 5 one-off in-app purchases. Electronics Reference Toolkit asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.8 for Electronics Kit against 4.9 for Electronics Reference Toolkit. That said, the two scores are not equally well evidenced: Electronics Kit has 65 ratings behind it against 7, so its average is the more settled of the two.
Electronics Kit ships an update every 6 weeks, Electronics Reference Toolkit fortnightly. The most recent releases landed on October 10, 2026 and October 6, 2026 respectively.
