# Zobi vs HydroHeros

The clearest difference is monetization model: HydroHeros at freemium against Zobi's subscription. HydroHeros also leads on review sentiment (100% vs 75%) and rating (5.0 vs 4.8). Zobi's advantage is ratings volume (26 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Zobi sells 2 in-app purchases, starting at $5.99 per month and HydroHeros sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

HydroHeros holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Zobi has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 75% of Zobi's written reviews are positive against 100% of HydroHeros's.

Zobi ships an update monthly, HydroHeros every 3 weeks. The most recent releases landed on October 28, 2026 and October 31, 2026 respectively.
