# 年轮 vs Memory Ark

The clearest difference is update cadence: 年轮 at every 5 days against Memory Ark's every 2 months. 年轮 also leads on ratings volume (103 vs 1). Memory Ark's advantage is rating (5.0 vs 4.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 年轮 sells 4 in-app purchases, starting at $0.99 per month and Memory Ark sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
