# 共此时 vs 53Hz

The clearest difference is rating: 共此时 at 5.0 against 53Hz's 3.8. 共此时 also leads on monetization model (free vs freemium) and iOS requirement (15.5 vs 17.0). 53Hz's advantage is update cadence (every 2 days vs every 9 days). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. 共此时 sells 9 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.
