# NHD vs CA STEAM

The clearest difference is ads: CA STEAM at none against NHD's shown. CA STEAM also leads on rating (5.0 vs 4.7) and monetization model (free vs ad-supported). NHD's advantage is ratings volume (6 vs 1) and iOS requirement (14.0 vs 17.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CA STEAM holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: NHD has 6 ratings behind it against 1, so its average is the more settled of the two.

NHD ships an update every 11 months, CA STEAM every 8 months. The most recent releases landed on September 15, 2026 and September 18, 2026 respectively.
