# HeadsUp vs Water

The clearest difference is monetization model: HeadsUp at freemium against Water's subscription. HeadsUp also leads on rating (4.0 vs 3.5) and review sentiment (68% vs 39%). Water's advantage is ratings volume (23 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. HeadsUp sells 3 in-app purchases, starting at $0.99 per month and Water sells 5 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

HeadsUp holds the better App Store score, 4.0 against 3.5. That said, the two scores are not equally well evidenced: Water has 23 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 68% of HeadsUp's written reviews are positive against 39% of Water's.

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on November 3, 2026.
