# 小透明 vs 犬岛

The clearest difference is review sentiment: 小透明 at 81% against 犬岛's 11%. 犬岛's advantage is ads (none vs shown) and update cadence (every 3 days vs every 6 weeks). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. 小透明 sells 7 one-off in-app purchases and 犬岛 sells 10 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

犬岛 holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 14 and 32 respectively. Written reviews complicate that: 81% of 小透明's written reviews are positive against 11% of 犬岛's, so the app with the better star average is not the one people write more warmly about.

小透明 ships an update every 6 weeks, 犬岛 every 3 days. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
