# Biphase vs 房間的秘密

The clearest difference is in-app purchases: Biphase at none against 房間的秘密's 2. Biphase also leads on ads (none vs shown) and rating (4.8 vs 4.4). 房間的秘密's advantage is review sentiment (80% vs 56%). On price, ratings volume and device support there is nothing between them.

Both are free to download. 房間的秘密 sells 2 one-off in-app purchases. Biphase asks for nothing beyond the download.

Biphase holds the better App Store score, 4.8 against 4.4. Both are backed by a comparable volume of ratings — 9 and 9 respectively. Written reviews complicate that: 56% of Biphase's written reviews are positive against 80% of 房間的秘密's, so the app with the better star average is not the one people write more warmly about.

Biphase ships an update fortnightly, 房間的秘密 monthly. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
