# Electronics Circuit Calculator vs Power Electronics

The clearest difference is rating: Power Electronics at 5.0 against Electronics Circuit Calculator's 4.5. Electronics Circuit Calculator's advantage is update cadence (every 5 days vs every 2 months) and monetization model (free vs free with in-app purchases). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Electronics Circuit Calculator sells 6 one-off in-app purchases and Power Electronics sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Power Electronics holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Electronics Circuit Calculator has 62 ratings behind it against 1, so its average is the more settled of the two.

Electronics Circuit Calculator ships an update every 5 days, Power Electronics every 2 months. The most recent releases landed on September 15, 2026 and September 18, 2026 respectively.
