# 小透明 vs 53Hz

The clearest difference is ads: 53Hz at none against 小透明's shown. 53Hz also leads on update cadence (every 2 days vs every 6 weeks) and review sentiment (100% vs 81%). 小透明's advantage is ratings volume (13 vs 3) and iOS requirement (15.0 vs 17.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. 小透明 sells 12 one-off in-app purchases and 53Hz sells 4 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.3 for 小透明 against 4.3 for 53Hz. Both are backed by a comparable volume of ratings — 13 and 3 respectively. Written reviews are what separate them: 81% of 小透明's written reviews are positive against 100% of 53Hz's.

小透明 ships an update every 6 weeks, 53Hz every 2 days. Both last shipped on October 20, 2026.
