# Atoms HD vs Kristoon

The clearest difference is rating: Atoms HD at 3.6 against Kristoon's 3.0. Atoms HD also leads on ads (none vs shown) and ratings volume (19 vs 1). Kristoon's advantage is update cadence (fortnightly vs every 64 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Atoms HD sells 7 one-off in-app purchases and Kristoon sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Atoms HD holds the better App Store score, 3.6 against 3.0. That said, the two scores are not equally well evidenced: Atoms HD has 19 ratings behind it against 1, so its average is the more settled of the two.

Atoms HD ships an update every 64 months, Kristoon fortnightly. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
