# Electronics Toolkit! vs Simurelay

The clearest difference is ads: Simurelay at none against Electronics Toolkit!'s shown. Simurelay also leads on review sentiment (52% vs 38%). Electronics Toolkit!'s advantage is rating (4.3 vs 3.9) and update cadence (every 2 months vs every 7 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Electronics Toolkit! sells 1 one-off in-app purchase and Simurelay sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Electronics Toolkit! holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Electronics Toolkit! has 556 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 38% of Electronics Toolkit!'s written reviews are positive against 52% of Simurelay's, so the app with the better star average is not the one people write more warmly about.

Electronics Toolkit! ships an update every 2 months, Simurelay every 7 months. The most recent releases landed on September 29, 2026 and September 27, 2026 respectively.
