# Tone generator vs BlueTooth for Arduino

The clearest difference is rating: Tone generator at 4.0 against BlueTooth for Arduino's 2.5. Tone generator also leads on ratings volume (155 vs 2) and iOS requirement (12.0 vs 14.4). BlueTooth for Arduino's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Tone generator sells 3 one-off in-app purchases. BlueTooth for Arduino asks for nothing beyond the download.

Tone generator holds the better App Store score, 4.0 against 2.5. That said, the two scores are not equally well evidenced: Tone generator has 155 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 68% of Tone generator'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.
