# ArduinoBlue vs Arduino BT Controller

The clearest difference is rating: ArduinoBlue at 4.5 against Arduino BT Controller's 2.0. ArduinoBlue also leads on review sentiment (90% vs 50%) and in-app purchases (none vs 1). Arduino BT Controller's advantage is update cadence (every 8 days vs every 9 months). On price there is nothing between them.

Both are free to download. Arduino BT Controller sells 1 one-off in-app purchase. ArduinoBlue asks for nothing beyond the download.

ArduinoBlue holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: ArduinoBlue has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 90% of ArduinoBlue's written reviews are positive against 50% of Arduino BT Controller's.

ArduinoBlue ships an update every 9 months, Arduino BT Controller every 8 days. The most recent releases landed on October 1, 2026 and October 2, 2026 respectively.
