# SuppCo vs Zest

The clearest difference is in-app purchases: Zest at none against SuppCo's 5. SuppCo's advantage is ratings volume (31K vs 1) and chart position (#58 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. SuppCo sells 5 in-app purchases, starting at $39.99 per year. 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: SuppCo has 31K ratings behind it against 1, so its average is the more settled of the two.

SuppCo ships an update every 6 weeks, Zest every 3 weeks. The most recent releases landed on October 22, 2026 and October 10, 2026 respectively.
