# YBox vs Zerk

The clearest difference is in-app purchases: Zerk at none against YBox's 17. Zerk also leads on rating (5.0 vs 4.7). YBox's advantage is ratings volume (229 vs 1) and iOS requirement (11.0 vs 16.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. YBox sells 17 in-app purchases, starting at $1.99 per month. Zerk asks for nothing beyond the download.

Zerk holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: YBox has 229 ratings behind it against 1, so its average is the more settled of the two.

YBox ships an update every 5 weeks, Zerk monthly. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
