# Blue Switch vs BlueTooth for Arduino

The clearest difference is review sentiment: BlueTooth for Arduino at 100% against Blue Switch's 17%. BlueTooth for Arduino also leads on in-app purchases (none vs 1) and ads (none vs shown). Blue Switch's advantage is rating (3.8 vs 2.5) and ratings volume (43 vs 2). On price and device support there is nothing between them.

Both are free to download. Blue Switch sells 1 one-off in-app purchase. BlueTooth for Arduino asks for nothing beyond the download.

Blue Switch holds the better App Store score, 3.8 against 2.5. That said, the two scores are not equally well evidenced: Blue Switch has 43 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 17% of Blue Switch's written reviews are positive against 100% of BlueTooth for Arduino's, so the app with the better star average is not the one people write more warmly about.
