# Zooblox vs CPI

The clearest difference is rating: Zooblox at 5.0 against CPI's 4.5. Zooblox also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). CPI's advantage is ratings volume (12K vs 2). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Zooblox holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: CPI has 12K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of Zooblox's written reviews are positive against 80% of CPI's.

Zooblox ships an update fortnightly, CPI every 2 months. The most recent releases landed on November 3, 2026 and November 6, 2026 respectively.
