# OLM vs H2C

The clearest difference is rating: H2C at 5.0 against OLM's 2.1. OLM's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. OLM sells 3 one-off in-app purchases 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 2.1. That said, the two scores are not equally well evidenced: OLM has 11 ratings behind it against 1, so its average is the more settled of the two.

OLM ships an update weekly, H2C every 2 weeks. The most recent releases landed on October 7, 2026 and October 16, 2026 respectively.
