# Zepp vs ONE SMARTWATCH

The clearest difference is rating: Zepp at 4.6 against ONE SMARTWATCH's 4.0. Zepp also leads on ads (none vs shown) and update cadence (weekly vs every 2 months). ONE SMARTWATCH's advantage is in-app purchases (none vs 18) and iOS requirement (13 vs 15.0). On price and device support there is nothing between them.

Both are free to download. Zepp sells 15 in-app purchases, starting at $3.99 per month. ONE SMARTWATCH asks for nothing beyond the download.

Zepp holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Zepp has 83K ratings behind it against 2, so its average is the more settled of the two.

Zepp ships an update weekly, ONE SMARTWATCH every 2 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
