# Onluyen vs H2C

The clearest difference is rating: H2C at 5.0 against Onluyen's 2.9. Onluyen's advantage is ads (none vs shown) and ratings volume (231 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Onluyen sells 5 in-app purchases, starting at $4.49 per month and H2C sells 3 in-app purchases, starting at $2.49 per 7 days. Whichever you choose, the download price is not the number that matters.

H2C holds the better App Store score, 5.0 against 2.9. That said, the two scores are not equally well evidenced: Onluyen has 231 ratings behind it against 1, so its average is the more settled of the two.

Onluyen ships an update every 11 days, H2C every 9 days. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
