# Bluetooth for Arduino vs AiK Keytool

The clearest difference is rating: Bluetooth for Arduino at 3.4 against AiK Keytool's 3.0. Bluetooth for Arduino also leads on ratings volume (42 vs 2). AiK Keytool's advantage is update cadence (every 2 weeks vs every 2 months) and iOS requirement (13 vs 18.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Bluetooth for Arduino sells 5 one-off in-app purchases and AiK Keytool sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Bluetooth for Arduino holds the better App Store score, 3.4 against 3.0. That said, the two scores are not equally well evidenced: Bluetooth for Arduino has 42 ratings behind it against 2, so its average is the more settled of the two.

Bluetooth for Arduino ships an update every 2 months, AiK Keytool every 2 weeks. The most recent releases landed on October 25, 2026 and October 3, 2026 respectively.
