ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Bluetooth for Arduino ships an update every 2 months, Blynk IoT monthly. The most recent releases landed on October 25, 2026 and October 30, 2026 respectively.
