# Electronics Circuit Calculator vs Arduino Pocket Reference

The clearest difference is rating: Electronics Circuit Calculator at 4.4 against Arduino Pocket Reference's 2.5. Electronics Circuit Calculator also leads on ads (none vs shown) and update cadence (every 5 days vs every 5 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Electronics Circuit Calculator sells 6 one-off in-app purchases and Arduino Pocket Reference sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Electronics Circuit Calculator holds the better App Store score, 4.4 against 2.5. Both are backed by a comparable volume of ratings — 64 and 19 respectively. Written reviews point the same way: 33% of Electronics Circuit Calculator's written reviews are positive against 12% of Arduino Pocket Reference's.

Electronics Circuit Calculator ships an update every 5 days, Arduino Pocket Reference every 5 months. The most recent releases landed on November 6, 2026 and November 1, 2026 respectively.
