# Zepp vs Zen Fast

The clearest difference is in-app purchases: Zen Fast at none against Zepp's 18. Zen Fast also leads on rating (5.0 vs 4.6) and iOS requirement (11.0 vs 15.0). Zepp's advantage is ratings volume (83K vs 4) and chart position (#189 vs unranked). On price there is nothing between them.

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

Zen Fast holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Zepp has 83K ratings behind it against 4, so its average is the more settled of the two.
