# Pool Log vs PoolVault

The clearest difference is monetization model: Pool Log at free against PoolVault's freemium. Pool Log also leads on ratings volume (6 vs 1). PoolVault's advantage is rating (5.0 vs 4.7) and iOS requirement (16.0 vs 26.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Pool Log sells 2 in-app purchases, starting at $0.99 per month and PoolVault sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

PoolVault holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Pool Log has 6 ratings behind it against 1, so its average is the more settled of the two.

Pool Log ships an update every 2 weeks, PoolVault fortnightly. The most recent releases landed on August 19, 2026 and September 29, 2026 respectively.
