# Bluetooth for Arduino vs Blynk IoT

The clearest difference is rating: Blynk IoT at 4.5 against Bluetooth for Arduino's 3.4. Blynk IoT also leads on ratings volume (828 vs 42). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Bluetooth for Arduino sells 5 one-off in-app purchases and Blynk IoT sells 7 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Blynk IoT holds the better App Store score, 4.5 against 3.4. That said, the two scores are not equally well evidenced: Blynk IoT has 828 ratings behind it against 42, so its average is the more settled of the two. Written reviews complicate that: 46% of Bluetooth for Arduino's written reviews are positive against 42% of Blynk IoT's, so the app with the better star average is not the one people write more warmly about.

Bluetooth for Arduino ships an update every 2 months, Blynk IoT monthly. Both last shipped on November 3, 2026.
