# 地下道 vs POOLS™

地下道 and POOLS™ both sit at 4.6 stars, but that hides the real split: 79% of POOLS™'s written reviews are positive against 30% of 地下道's. POOLS™ also leads on ratings volume (1.6K vs 5). 地下道's advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. POOLS™ sells 1 one-off in-app purchase. 地下道 asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for 地下道 against 4.5 for POOLS™. That said, the two scores are not equally well evidenced: POOLS™ has 1.6K ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 30% of 地下道's written reviews are positive against 79% of POOLS™'s.
