# SMART vs ONE SMARTWATCH

The clearest difference is rating: SMART at 4.5 against ONE SMARTWATCH's 3.0. SMART also leads on ratings volume (1.4K vs 1). ONE SMARTWATCH's advantage is in-app purchases (none vs 12). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. SMART sells 12 one-off in-app purchases. ONE SMARTWATCH asks for nothing beyond the download.

SMART holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: SMART has 1.4K ratings behind it against 1, so its average is the more settled of the two.

SMART ships an update monthly, ONE SMARTWATCH every 2 months. The most recent releases landed on October 20, 2026 and October 3, 2026 respectively.
