# Atomus HD vs Niki Play

The clearest difference is review sentiment: Atomus HD at 91% against Niki Play's 0%. Atomus HD also leads on ratings volume (60 vs 1) and chart position (#199 vs unranked). Niki Play's advantage is rating (5.0 vs 4.8) and iOS requirement (13.0 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Atomus HD costs $3.99 and Niki Play $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Niki Play holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Atomus HD has 60 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 91% of Atomus HD's written reviews are positive against 0% of Niki Play's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on September 22, 2026 and June 3, 2026 respectively.
