# PoolSync vs Raindrip

The clearest difference is update cadence: PoolSync at every 2 months against Raindrip's every 22 months. PoolSync also leads on review sentiment (20% vs 0%) and ratings volume (64 vs 7). Raindrip's advantage is iOS requirement (13.0 vs 15.1). On price, rating, 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.

Raindrip holds the better App Store score, 2.3 against 2.1. That said, the two scores are not equally well evidenced: PoolSync has 64 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 20% of PoolSync's written reviews are positive against 0% of Raindrip's, so the app with the better star average is not the one people write more warmly about.

PoolSync ships an update every 2 months, Raindrip every 22 months. The most recent releases landed on September 18, 2026 and June 1, 2026 respectively.
