# Gyroscope vs Zest

The clearest difference is in-app purchases: Zest at none against Gyroscope's 17. Zest also leads on ads (none vs shown) and rating (5.0 vs 4.8). Gyroscope's advantage is ratings volume (49 vs 1) and update cadence (weekly vs every 3 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Gyroscope sells 15 in-app purchases, starting at $9.00 per 7 days. Zest asks for nothing beyond the download.

Zest holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Gyroscope has 49 ratings behind it against 1, so its average is the more settled of the two.

Gyroscope ships an update weekly, Zest every 3 weeks. The most recent releases landed on September 26, 2026 and September 8, 2026 respectively.
