# Electronics Kit vs OhmsLab

The clearest difference is update cadence: OhmsLab at every 3 weeks against Electronics Kit's every 6 weeks. Electronics Kit's advantage is device support (3 vs 1) and iOS requirement (9.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Electronics Kit sells 5 one-off in-app purchases and OhmsLab 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, OhmsLab every 3 weeks. The most recent releases landed on October 20, 2026 and October 11, 2026 respectively.
