Verdict
The clearest difference is update cadence: EngKit at fortnightly against Electronics Kit's every 6 weeks. Electronics Kit's advantage is iOS requirement (9.0 vs 26.1). On price, ads, in-app purchases and device support 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 and EngKit sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Electronics Kit ships an update every 6 weeks, EngKit fortnightly. Both last shipped on October 29, 2026.
