# iRotorBalancer vs Bluetooth for Arduino

The clearest difference is price: Bluetooth for Arduino at Free against iRotorBalancer's $799.99. Bluetooth for Arduino also leads on ratings volume (42 vs 1). iRotorBalancer's advantage is rating (5.0 vs 3.4) and iOS requirement (11.0 vs 18.5). On update cadence, ads, in-app purchases and device support there is nothing between them.

Bluetooth for Arduino is free to download; iRotorBalancer costs $799.99 up front. iRotorBalancer sells 2 one-off in-app purchases and Bluetooth for Arduino sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

iRotorBalancer holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Bluetooth for Arduino has 42 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 29, 2026 and October 25, 2026 respectively.
