# PoolSync vs I

The clearest difference is rating: I at 3.3 against PoolSync's 2.0. I also leads on review sentiment (50% vs 20%). PoolSync's advantage is ratings volume (68 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

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

I holds the better App Store score, 3.3 against 2.0. That said, the two scores are not equally well evidenced: PoolSync has 68 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 20% of PoolSync's written reviews are positive against 50% of I's.

PoolSync ships an update every 2 months, I monthly. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
