Verdict

The call

The clearest difference is rating: BlueGrays at 4.4 against Learn About Electronics's 3.5. BlueGrays also leads on update cadence (every 6 days vs every 3 weeks) and ratings volume (11 vs 2). Learn About Electronics's advantage is review sentiment (100% vs 64%) and ads (none vs shown). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Learn About Electronics sells 1 one-off in-app purchase and BlueGrays sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

BlueGrays holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: BlueGrays has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Learn About Electronics's written reviews are positive against 64% of BlueGrays's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Learn About Electronics ships an update every 3 weeks, BlueGrays every 6 days. The most recent releases landed on June 1, 2026 and September 17, 2026 respectively.
