# EE ToolKit vs Arduino Pocket Reference

The clearest difference is review sentiment: EE ToolKit at 90% against Arduino Pocket Reference's 12%. EE ToolKit also leads on rating (4.7 vs 2.4) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

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

EE ToolKit holds the better App Store score, 4.7 against 2.4. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 90% of EE ToolKit's written reviews are positive against 12% of Arduino Pocket Reference's.

EE ToolKit ships an update every 3 months, Arduino Pocket Reference every 5 months. The most recent releases landed on September 23, 2026 and June 2, 2026 respectively.
