# Bluetooth for Arduino vs Bluetooth Serial Connect

The clearest difference is review sentiment: Bluetooth for Arduino at 46% against Bluetooth Serial Connect's 0%. Bluetooth for Arduino also leads on ads (none vs shown) and update cadence (every 2 months vs every 10 months). Bluetooth Serial Connect's advantage is in-app purchases (none vs 5) and rating (3.7 vs 3.5). On price and device support there is nothing between them.

Both are free to download. Bluetooth for Arduino sells 5 one-off in-app purchases. Bluetooth Serial Connect asks for nothing beyond the download.

Bluetooth Serial Connect holds the better App Store score, 3.7 against 3.5. That said, the two scores are not equally well evidenced: Bluetooth for Arduino has 44 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 46% of Bluetooth for Arduino's written reviews are positive against 0% of Bluetooth Serial Connect's, so the app with the better star average is not the one people write more warmly about.

Bluetooth for Arduino ships an update every 2 months, Bluetooth Serial Connect every 10 months. The most recent releases landed on September 21, 2026 and July 21, 2026 respectively.
