# SPACE vs 白丁友记

SPACE and 白丁友记 both sit at 3.9 stars, but that hides the real split: 100% of 白丁友记's written reviews are positive against 51% of SPACE's. SPACE's advantage is ratings volume (45 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. SPACE sells 4 in-app purchases, starting at $3.99 per 3 months and 白丁友记 sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
