# DSD TECH Bluetooth vs Arduino BT Controller

The clearest difference is rating: DSD TECH Bluetooth at 2.8 against Arduino BT Controller's 2.0. DSD TECH Bluetooth also leads on in-app purchases (none vs 1) and ads (none vs shown). Arduino BT Controller's advantage is update cadence (every 8 days vs every 2 months) and review sentiment (50% vs 40%). On price there is nothing between them.

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

DSD TECH Bluetooth holds the better App Store score, 2.8 against 2.0. That said, the two scores are not equally well evidenced: DSD TECH Bluetooth has 18 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 40% of DSD TECH Bluetooth's written reviews are positive against 50% of Arduino BT Controller's, so the app with the better star average is not the one people write more warmly about.

DSD TECH Bluetooth ships an update every 2 months, Arduino BT Controller every 8 days. The most recent releases landed on September 29, 2026 and October 2, 2026 respectively.
