# Joo vs Tezzy

The clearest difference is in-app purchases: Joo at none against Tezzy's 5. Joo also leads on ads (none vs shown) and ratings volume (8 vs 1). Tezzy's advantage is update cadence (every 5 days vs every 2 weeks). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. Tezzy sells 5 in-app purchases, starting at $0.99 per month. Joo asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Joo against 5.0 for Tezzy. That said, the two scores are not equally well evidenced: Joo has 8 ratings behind it against 1, so its average is the more settled of the two.

Joo ships an update every 2 weeks, Tezzy every 5 days. The most recent releases landed on September 21, 2026 and September 17, 2026 respectively.
